Description

Technical Field

[0001] The present invention belongs to the field of optical technology, and relates to a positioning system and method for each optical functional unit in an optical path, and particularly relates to an optical positioning system and method based on a positioning block and a functional module.

Background Art

[0002] Currently, in the laboratory, when constructing an optical system, it is necessary to use a multi- dimensional adjustment frame to adjust the optical path of the system. In some complex optical systems, a large amount of work needs to be spent on constructing the optical path. Also, due to the excessive freedom of the optical path, the system has almost no reproducibility, and it is necessary to readjust the system every time the optical path structure changes. As a result, a lot of time and labor are wasted. To overcome the drawbacks of the prior art, the present invention provides a positioning block, an optical positioning system and method using the positioning block, and its positioning block and functional module, which can quickly achieve the construction and positioning of the optical functional units in the optical path

Summary of the Invention

[0003] The following will describe the specific content of the positioning block of the present invention, the optical positioning system and method based on the positioning block, and the functional module.

[0004] I. The positioning block of the present invention

[0005] The positioning block of the present invention has a bottom surface, a top surface on which an optical unit can be mounted, and at least one Includes two positioning sides.

[0006] Furthermore, the positioning block has two mutually perpendicular positioning sides.

[0007] Furthermore, the positioning block has a block structure (square block structure), and the bottom surface is oriented downwards. It has four straight positioning sides. The horizontal cross-section of the positioning block is rectangular, and the same size It may be a rectangle, or it may be a modular design. This is known as modular design. This means that the size of the plane is based on a square with the shortest side length as the basic cell, and the length or width is an integer multiple of the shortest side length. This means that a rectangle or square having can be designed. For example, the basic cell is 1x1. Yes, and other blocks in the modular design may be 1x2, 1x3, or 2x2. The block of the present invention is not a geometrically strict hexahedron, but rather has chamfers or bevels at each corner. It may have a smooth transition. Therefore, a polygonal prism (for example, with chamfers added to the four side positions) It is sometimes represented as an octagonal prism (when processed), but If a block has four sides perpendicular to it, it falls under the category of the block described in the present invention, and its horizontal cross-section is rectangular. It is considered to be. In the present invention, the positioning block of the block structure is the positioning block It may be referred to as such, or abbreviated as "block."

[0008] In a preferred configuration, a magnet is embedded in the bottom surface of the positioning block.

[0009] In a preferred configuration, magnets are embedded in the positioning side of the positioning block.

[0010] In a preferred configuration, the positioning block of the block structure uses a magnetic material, and four positions Magnets are embedded in the positioning side. Furthermore, magnets are embedded in the four positioning sides. The positions are uniformly shifted to either the left or right, avoiding the middle position, and each magnet is embedded in a polarity. The direction is the same.

[0011] 2. Optical positioning system based on the positioning block of the present invention

[0012] A base plate with one horizontal top surface, at least one support member, and mounting of an optical function unit. It includes a plurality (at least two) positioning blocks for positioning, and the bottom plate is an optical system The mounting platform of the TEM, i.e., the horizontal reference plane and vertical (Z-direction) of the optical system. It provides initial positioning. The support member and the base plate are either an integrated structure or a separate structure, and the support member is Having at least one straight positioning side, the initial horizontal positioning block It provides precise positioning. The bottom surface of the positioning block can be in close contact with the top surface of the bottom plate, and positioning The positioning side of the block can be in close contact with the positioning side of the support member, and the positioning block The top of the cubicle can accommodate an optical unit. In this invention, the bottom plate and support member are positioned These are collectively referred to as "selection discs."

[0013] When the constructed optical system extends in only one direction (X direction) in the horizontal plane, the present invention The optical axis of the optical unit in different positioning blocks is parallel to the positioning side and They should be positioned so that the distance is the same. In this way, the positioning of different positioning blocks is determined. When the side surface is in close contact with the positioning side of the support member, the optical unit in different positioning blocks It is possible to ensure that the optical axes of the knit are on the same vertical plane. Depending on the requirements of the optical path, Furthermore, if the optical axis of the optical unit is installed such that it has the same height and is parallel to the bottom surface of the positioning block, the optical axes of the optical units in different positioning blocks will be on the same horizontal straight line.

[0014] In some optical paths, the optical unit needs to be positioned in two perpendicular directions (X direction and Y direction) of a plane. In this case, the present invention provides a support member having two positioning side edges (X direction and Y direction) perpendicular to each other. The support member may be of a single structure or may be two support members perpendicular to each other. The positioning block may have two positioning side surfaces perpendicular to each other. One positioning side surface is parallel to the optical axis, and the other positioning side surface is perpendicular to the optical axis. Thus, when the positioning side surfaces of different positioning blocks are respectively in close contact with the X-direction positioning side edge and the Y-direction positioning side edge of the support member, positioning in the X direction and the Y direction can be realized. What is realized by the positioning block in the above technical solution is the directional positioning of the optical path, and the distance between different positioning blocks is adjusted by sliding the positioning block along the support member. Thus, the distance between the optical units can be changed without changing the optical path direction.

[0015]

[0016] In some cases, not only positioning in the X direction and the Y direction is required, but accurate distance positioning in these two directions also needs to be realized. This need may be realized by adopting a positioning block with a block structure, and such a positioning block may be referred to as a positioning square block. The bottom surface of each positioning square block can be in close contact with the bottom plate. ​​​​​​​​​​ The sides of the block are perpendicular to the bottom surface and can be in close contact with the support members and the sides of different blocks. Yes, an optical function unit can be mounted on the top surface of all or some of the blocks, and the block The horizontal cross-section is rectangular, and may be rectangles of the same size, even in modular designs. Good. In this way, the positioning side of the support member provides initial positioning in the X and Y directions, The placement blocks are continuously in close contact and extend, allowing for precise distance positioning between optical units. This is achieved, and the distance is exactly an integer multiple of the edge length of the basic block cell.

[0017] If the base plate and support members are inseparable, a movable mounting plate can be added to the base plate. One side or at least two vertical sides of the mounting plate can be in close contact with the support member, The bottom surface of the lock can be in close contact with the top surface of the mounting plate.

[0018] 3. Optical system positioning method based on the positioning block of the present invention

[0019] The base plate or mounting plate is the positioning reference in the vertical direction (Z direction), and the support member on the base plate Using the horizontal (X and / or Y) direction as the positioning reference, and based on different optical path designs, Different positioning blocks with or without the academic unit installed are placed on the base plate and support By ensuring close contact between the holding member and the positioning blocks, the optical path can be quickly positioned. This can be achieved quickly. The planar direction is one-dimensional positioning (single direction), or Is it 2D positioning (vertical X and Y directions) and does it require precise distance positioning? Based on this, the method is specifically as follows:

[0020] When performing only one-dimensional positioning, the positioning side of the positioning block is aligned with the same position as the support member. Position it tightly against the designated edge. Position the optical axis of the optical unit in different positioning blocks. They should be installed parallel to the sides and at the same distance. This will allow different positions When the positioning side of the fixing block is in close contact with the positioning side of the support member, different positioning blocks This ensures that the optical axes of the optical units in the lock are on the same vertical plane. Depending on the requirements of the optical path, the optical axis of the optical unit may be positioned at the same height as the positioning block. When installed parallel to the bottom surface of the block, the optical unit in different positioning blocks The optical axes of the lights are on the same horizontal line. The positioning block is slid along the support member. This allows for approximate adjustment of the distance between optical units.

[0021] Two-dimensional positioning is required, that is, the optical unit in two vertical directions (X direction) of the plane. When positioning in the X and Y directions, two positioning sides perpendicular to each other (X and Y directions) ) Utilizing a support member equipped with ), the positioning block has two mutually perpendicular positioning sides It is possible for one positioning side to be parallel to the optical axis, and the other positioning side to be parallel to the optical axis. It is vertical. Based on the optical path design, different positioning blocks are positioned in the required direction. It is brought into close contact with the corresponding position on the required side. This allows the position of different positioning blocks. The positioning sides are in close contact with the positioning sides in the X and Y directions of the support member, respectively. This enables positioning in the X and Y directions. Positioning along the support member The distance between optical units can be roughly adjusted by sliding the lock.

[0022] Not only does it require two-dimensional positioning in the X and Y directions, but also precise positioning in these two directions. When distance positioning is required, this need can be met by positioning rectangular blocks. This is possible. The bottom surface of each positioning rectangular block is in close contact with the base plate, and the sides of the block are at the bottom It is perpendicular to the surface, in close contact with the support member and the sides of different blocks, and all or some of the blocks An optical function unit is mounted on the top surface. In this way, the positioning side of the support member This provides initial positioning in the X and Y directions, and the positioning rectangular blocks are continuously in close contact with each other. By extending the optical units, precise distance positioning is achieved, and that distance is strictly within the basic block. It is an integer multiple of the side length of the xel.

[0023] As an example of the need for two-dimensional and precise distance positioning as described above, the present invention further involves the light The positioning method will be explained. Based on different optical path designs, the optical instrument will be placed in the block at the desired position. Equipped with a function unit, the upper optical function unit connects to all function units through its connection structure. The center point is positioned at the same height, and the light-emitting unit (e.g., laser, collimator, etc.) is positioned accordingly. ) The emitted light is parallel to one positioning side and bottom surface of the positioning block, and the other optical The center point of the unit is mechanically adjusted to coincide with the height of the emitted light, and the light is unit After passing through the pit, the optical fiber unit is adjusted so that the position and angle of the light do not change. As a result, light emitted from one emission unit passes through multiple optical units, It can be smoothly injected into final functional optical units such as collimators and detectors. In other words, the various optical function units are positioned relative to the top surface of the block at the light emission position or incidence position. The placement is designed to be at the same height and the horizontal position is aligned. Optical path is adjusted as needed. Multiple blocks equipped with functional units are placed in corresponding positions on the block array on the base plate. This allows for nearly precise positioning of the optical system. By adding an adjustment structure, the optical function unit can be fine-tuned, different blocks This allows for further improvement in the alignment and coupling accuracy of optical units. Typically, the size of The needs can be met by using all the blocks, which are the basic cells that are set up. However, The modular design, with blocks of different sizes, meets more flexible needs and position This can improve the efficiency and accuracy of positioning. For example, the bottom of the optical function unit is the base If the size of the cell block is exceeded, a larger block can be used, and adjacent light When the distance between academic function units is large, blocks with appropriate specifications can be used. This reduces the total number of blocks in the optical system, improves positioning speed, and increases accuracy. .

[0024] Such optical positioning systems and methods may or may not incorporate an optical function unit. Any of the following blocks can be replaced with any other block, and by doing so... This enables the rapid construction and reconstruction of optical paths.

[0025] The tight fit between the block and the support member, between the block and the base plate or mounting plate, and between the blocks. To achieve this, it is possible to create a natural bond, but to achieve a more reliable bond... Therefore, the following technical proposals can be adopted.

[0026] In one embodiment, the space between the block and the base plate or support plate, and between the blocks, is sealed with adhesive. They are glued together and tightly adhered.

[0027] In other embodiments, the base plate or mounting plate may be made of a magnetic material (not the magnet itself, but something that does not affect the magnetic field) This refers to a material that reacts in that manner, and in this invention, it refers to a material that can be attracted to a magnet. The positioning block used is a positioning block in which a magnet is embedded in the bottom surface as described above. This ensures that the positioning block and the base plate or mounting plate are securely held together by suction. Furthermore, if a rectangular positioning block is used, the magnetic material is It is used, and magnets are embedded in the four positioning sides. They are embedded, and their positions are uniformly shifted to either the left or right, avoiding the middle position, with each magnet embedded. The polarity direction is the same. In this way, when adjacent blocks approach each other, they attract each other. , and they adhere tightly. In addition, magnetic materials can be used for the support members, thereby, This allows for a tight, secure fit between the lock and the support member.

[0028] IV. Functional module based on the positioning block of the present invention

[0029] The positioned optical path system described above has its positioning block facing the base plate or mounting plate. By fixing it in place, it forms a more stable system, i.e., the functional module of the present invention. Based on a more reliable and different method of contact achieved between the above system units, The formed functional modules are as follows:

[0030] Functional module fixed with adhesive: Positioned, with or equipped with an optical unit A positioning block that is not installed, and a base plate or that is bonded and fixed to the positioning block. Includes a mounting plate. The positioning block is bonded to the base plate and the support member and the base plate are inseparable. If functional, the functional module further includes support members.

[0031] Magnetically attached functional module: Positioned, with or equipped with an optical unit. A positioning block that has not been positioned, and a base plate or mounting plate to which the positioning block is magnetically attached. This includes the positioning block being attracted to the base plate and the support member and the base plate being inseparable. In this case, the functional module further includes support members.

[0032] In this invention, the base plate, support member, and block, which serve as limiting elements, are made of a rigid material that is easy to process. The materials used are stainless steel, aluminum, ceramic, crystalline silicon, and single-crystal silicon. These may be, but are not limited to, other materials. These materials are easy to process and have flat surfaces. It ensures high degree of durability, high wear resistance, and high stability. It is integrally molded through a predetermined processing process. This reduces processing errors.

[0033] In this invention, the present invention relates to light-emitting elements such as laser emitting elements and optical fiber collimators. If present, the beam emitted from the block can be directed to the block by an adjustment frame or pre-fixing. So that it is perfectly parallel to the bottom and sides, between blocks, the bottom If the beam is in close contact with the support member, the beam will transmit smoothly from one block to another. It is sent and received by any detector in another block, such as a collimator or power meter. The continuous structure of the optical function unit and the pre-adjustment of the optical path employ various conventional techniques. This allows for further improvement of alignment accuracy and coupling efficiency, as needed. Depending on the situation, you can also add multiple fine-tuning mechanisms to the block. [Effects of the Invention]

[0034] As described above, in the present invention, the precise positioning of each block optical element is supported by the block and support This can be achieved easily and quickly through the tight adhesion between the components and blocks. The optical functional unit in the block has an angle of the optical path after the optical path has passed through this optical element. They may be fixed by an adjustment frame or pre-adjustment so that their position does not have any effect. This enables the exchange and reconfiguration of any optical elements.

[0035] This invention is particularly suitable for education and research. The construction of a single optical path in education is for educational demonstrations or This is solely for student practice, and the construction of one optical path in research serves only one experimental purpose. This is a possibility. Optical paths constructed under such circumstances can be stored for long periods and reused multiple times. This invention does not require any additional steps, is very cost-effective, convenient and easy to implement, and can be done at any time. We provide a method for constructing optical paths that can be deconstructed and reconstructed. [Brief explanation of the drawing]

[Figure 3] This is a schematic top view of Example 2-1 of the present invention. [Figure 4] This is a schematic perspective view of Invention Example 2-1. [Figure 5] This is a schematic perspective view of Example 2-2 of the present invention. [Figure 6] A schematic perspective view of Example 3-1 of the present invention. [Figure 7] A schematic perspective view of Example 3-2 of the present invention. [Modes for carrying out the invention]

[0037] The embodiments of the present invention will be described below with reference to the drawings. The block, positioning system and method, and functional module are used in the positioning system. The optical units in the embodiments are all collimators, but the optical unit of the present invention The knit is not limited to the collimator. The present invention provides positioning in the technical proposal of the present invention. Applicable to all possible optical units.

[0038] (Example 1-1)

[0039] As shown in Figures 1 and 2, the optical positioning system based on the positioning block is positioned Includes a positioning disk 1 and two positioning blocks 2 for positioning. 1 consists of a base plate 11 with a horizontal top surface and a single support member 1 with a straight inner side that serves as a positioning edge. It consists of 2, and block 2 includes one bottom surface and one positioning side surface, and top surface It is equipped with an optical unit, and in this embodiment, the optical unit is a collimator.

[0040] The positioning method using the positioning system of this embodiment is as follows: Positioning De The bottom plate 11 of disc 1 is used as the vertical (height) positioning reference, and the support members on the bottom plate 11 The 12 positioning sides are used as the horizontal positioning reference. The bottom surface of the positioning block is the bottom plate 1. By making contact with the upper surface, vertical positioning is achieved, and the position of the positioning block By ensuring close contact (making them tightly attached) between the side surface to be positioned and the side surface to be positioned of the support member, This enables horizontal positioning. The two positioning blocks 2 are connected to each other. It is equipped with collimator 4, and the optical axis of collimator 4 is each positioned by a block The positioning is parallel to the side of 2 and at a distance H=h (Figure 1), and the optical axis height of collimator 4 is Set them to the same settings. In this way, the optical axes of the two collimators 4 are positioned on the same horizontal line. The horizontal line is parallel to the positioning side of the base plate and support member. As can be seen from the drawing, The size and cross-sectional shape of the positioning blocks in this embodiment do not necessarily have to match; what is important is, The optical axis of the optical unit is parallel to the positioning side of the positioning block and the positioning side is parallel to the positioning side This means the distances are the same.

[0041] In order to ensure reliable contact and positioning between the positioning block 2 and the base plate 11, the base plate 11 employs magnetic material, and a magnet (not shown) is embedded in the bottom surface of the positioning block. The positioning block is then attached to the base plate by suction and secured. The material of the base plate 11 is limited to a magnetic material. Alternatively, the positioning block 2 and the base plate 11 may be fixed with adhesive. After fixing it in place, remove the support member or if the support member is not removed (the support member and the bottom plate are If inseparable, it becomes a functional module of the present invention.

[0042] (Examples 1-2)

[0043] This embodiment does not have drawings, so you may refer to Figure 5 of Embodiment 2-2.

[0044] In this embodiment, the support member and the base plate are inseparable. A movable mounting plate 3 is attached to the base plate. In addition, in Example 1-1, one side of the mounting plate 3 is in close contact with the positioning side of the support member 12. This differs from the previous version. The bottom surface of the positioning block 2 is in close contact with the mounting plate 3.

[0045] In this embodiment, the positioning disk 1 is made of a non-magnetic material, and the mounting plate 3 is made of a magnetic material. Therefore, block 2 adheres to the mounting plate 3 and becomes one unit, but does not adhere to the positioning disk. This integrates the mounting plate 3, block 2, and optical function unit from the positioning disc. It is easy to move and make it into an independent functional module. Furthermore, positioning can be done with adhesive. The lock 2 and mounting plate 3 are fixed in place, and the mounting plate 3, block 2, and optical function unit are positioned. It may also be moved from the disk as a single, independent functional module.

[0046] (Example 2-1)

[0047] As shown in Figures 3 and 4, the optical positioning system based on the positioning block is positioned It includes a positioning disk 1 and multiple positioning blocks 2. Positioning disk 1 is on It consists of a horizontal base plate 11 and support members 12 that are perpendicular to each other and have straight inner surfaces. Furthermore, the planes of each block 2 in the figure are squares of the same size, and the size of the planes is also It may be designed in a modular fashion, meaning that the size of the plane is based on a square with the shortest side length as the basic cell. This means that a rectangle or square with a length or width that is an integer multiple of the minimum side length can be designed. It tastes good.

[0048] Block 2 is integrally fabricated and formed using magnetic stainless steel or other magnetic material. Magnets 21 are embedded in each side of block 2. The position of the magnets 21 is at the intermediate position. Avoid them, and unify them to the left or right, with the polarity direction in which each magnet 21 is embedded being the same (i.e.) (The poles are unified to be either north or south, facing outwards.)

[0049] The positioning method using the positioning system of this embodiment is as follows: Positioning De The bottom plate 11 of disc 1 is used as the vertical (height) positioning reference, and the two sides of the bottom plate 11 The surface support member 12 is used as two horizontal positioning references. The bottom of block 1 and the bottom plate 11 and The close contact ensures vertical positioning, and the close contact between the edge of block 1 and the support member and adjacent Horizontal positioning is achieved by the close contact between the edges of the adjacent blocks. Block 2 Since magnets 21 are embedded in each side, they attract adjacent blocks 2 together to create a tight bond. It can be made to fit snugly. On the other hand, the magnet 21 on the side is not in the center, but is offset. Furthermore, the outer magnetic poles of magnet 22 are the same, and therefore all the blocks are oriented in the forward direction. Only when this condition is met will the blocks adhere to each other properly and form a tight bond.

[0050] The bottom plate 11 and the support member 12 may be made of a magnetic solid material, and the bottom surface of block 2 may also be made of a magnetic solid material. A magnet (not shown) is embedded. This allows block 2 to be supported by the base plate 11 and the support member. 12 can also be tightly attached by magnetic attraction.

[0051] Based on different optical path designs, the upper optical function unit is mounted in block 2 at the desired position. The upper optical function unit, through its connection structure, ensures that the center points of all function units are at the same height. The light-emitting unit (e.g., laser, collimator, etc.) is positioned so that the emitted light is directed to the position The side and bottom surfaces of the placement block are parallel, and the center point of the other optical units is at the height of the emitted light. Mechanically adjusted to match, and after the light passes through the unit, the position and angle of the light By adjusting the optical fiber unit so that it does not change, from one output unit The emitted light passes through multiple optical units, and then through final components such as collimators and detectors. It can smoothly enter the functional optical unit. Various optical functional units are block The light emission or incidence point is set to be at the same height as the top surface of the unit, and the horizontal position is aligned. It is designed. Depending on the optical path, multiple blocks equipped with optical function units are placed on the bottom plate. By placing it in the corresponding position on the block array above, the optical system can be positioned with near-perfect accuracy. This can be achieved by making multiple fine adjustments to the optical function unit. Precise positioning can be achieved (further improvement in alignment accuracy and coupling efficiency). To simplify things, you can also add multiple fine-tuning mechanisms to the block as needed. .

[0052] In this embodiment, collimator 4 is used as an example. In the schematic top view of Figure 3, the top and bottom are collimators. The remeter optical path is shown, and Figure 4 is a schematic perspective view of Figure 3 with the lower collimator removed. Yes, there are. As shown in Figure 3, there are three blocks 2 at the top, and there is a pair of blocks 2 at both ends. There is a coupled collimator 4, and the central block 2 does not have an optical function unit, It serves to lengthen the optical path. At the bottom, a pair of couplings are formed between two adjacent blocks 2. The collimator is fixed. As can be seen from Figures 3 and 4, Block 2 is of equal width and While the two are joined and in close contact, the coupling collimator 4 is positioned in the same location within block 2. They are attached and all are positioned parallel to and opposite the sides of block 2. Therefore, they are joined together. Collimator 4 can achieve horizontal alignment. Due to the connection structure, The center point of the collimator 4 is also aligned in the height (vertical) direction.

[0053] (Example 2-2)

[0054] In this embodiment, as shown in Figure 5, a movable mounting plate 3 is added to the base plate, and the mounting plate 3 is connected to each other This differs from Example 2-1 in that two sides perpendicular to the block are in close contact with the support member 12. The bottom surface of unit 2 is in close contact with the mounting plate 3.

[0055] In this embodiment, the positioning disk 1 is made of a non-magnetic material, and the mounting plate 3 is made of a magnetic material. Therefore, block 2 adheres to the mounting plate 3 and becomes one unit, but does not adhere to the positioning disk. This integrates the mounting plate 3, block 2, and optical function unit from the positioning disc. It is easy to move and make it into an independent functional module.

[0056] (Example 3-1)

[0057] This embodiment differs from Embodiment 2-1 in that, as shown in Figure 6, block 2 does not have a magnet. It is. A tight bond is achieved between Block 2 by using an adhesive bonding method. This also allows for a tight, secure fit between the block, the support member, and the base plate.

[0058] This embodiment is mainly used in optical paths using ultra-miniature optical functional units. Because the volume of Ku2 is very small, it becomes difficult to fabricate other structures on top of it. This structure is applicable to block 2 of various sizes, but is not limited to small ones. It is not. The adhesive is decomposable or dissolvable to facilitate further dismantling and reconstruction. A suitable adhesive can be used. The advantages of using this structure are as follows: (1) The choice of materials is more flexible, including aluminum alloys, quartz, single-crystal silicon, and ceramics. (2) Various metal and non-metallic materials that are easy to process and resistant to deformation can be used. After the adhesive has hardened, the entire bonded block is removed from positioning disc 1 and separated. It can be assembled into small modules. Alternatively, the entire structure can be positioned as a larger unit. The components 1, 2, and the optical path are bonded together to form a small, independent module. .

[0059] The mounting and pre-alignment of the optical function unit are the same as in Example 1-1. See also Figure 6. Similar to Figure 5, the coupled collimator 4 will be explained as an example, and all aspects are the same as those in Example 1-1. Therefore, it will not be repeated here.

[0060] (Example 3-2)

[0061] In this embodiment, as shown in Figure 7, a movable mounting plate 3 is added to the base plate, and the mounting plate 3 is connected to each other This differs from Example 3-1 in that two sides perpendicular to the block are in close contact with the support member 12. The bottom surface of block 2 is in close contact with the mounting plate 3. There is contact between the blocks 2 and between block 2 and the mounting plate. They are bonded together with an adhesive. After the adhesive hardens, the mounting plate 3, block 2 and optical function unit are bonded together. It is moved as a single unit from the positioning disk to form a single independent functional module. [Explanation of Symbols]
