Description

Technical Field

[0001] This utility model relates to the field of laser parameter measurement and imaging technology, and in particular to a single-camera dual-field-of-view adjustable optical path laser imaging device. Background Technology

[0002] Because laser systems require frequent debugging and maintenance, they need to utilize far-field and near-field measurement data of the laser to achieve rapid and automatic collimation of the optical path, thereby enabling the laser device to operate in its designed state.

[0003] Existing imaging devices for simultaneous near-field and far-field laser measurement typically use a motor to move a camera between the near and far fields, allowing the camera to measure the laser's near and far fields separately. However, because the motor-driven camera movement is not fast enough, the camera typically takes several seconds to move between the near and far fields, resulting in low measurement efficiency. Alternatively, a beam splitter can be used to split the laser into two paths, with the near-field camera positioned behind and below the beam splitter (i.e., the laser is split into two paths by the beam splitter), enabling the near-field and far-field cameras to acquire the laser's position and pointing parameters. However, near-field cameras are expensive, making them less economical, and the near-field and far-field cameras cannot be synchronized effectively, resulting in low synchronization.

[0004] In the process of developing this utility model, the applicant discovered at least the following problems in the prior art:

[0005] Existing laser imaging devices cannot adequately meet users' needs for measurement efficiency and simultaneous near-field and far-field imaging. Utility Model Content

[0034] To illustrate the technical solution described in this utility model, specific embodiments are described below, showing only the parts related to the embodiments of this utility model.

[0035] Example 1:

[0036] like Figure 1As shown, this utility model provides a single-camera, dual-field-of-view, adjustable optical path laser imaging device, including an imaging module 1, a beam splitting module 2, an optical path adjustment module 3, and a housing 4. The imaging module 1, beam splitting module 2, and optical path adjustment module 3 are all connected within the housing 4, with the beam splitting module 2 and imaging module 1 arranged sequentially along the input direction of the laser 5. The optical path adjustment module 3 is positioned below the imaging module 1. The beam splitting module 2 splits the laser 5 into a first beam 51 and a second beam 52, transmitting the first beam 51 to the imaging module 1 and the second beam 52 to the optical path adjustment module 3. The optical path adjustment module 3 adjusts the optical path of the second beam 52 and transmits the second beam 52 back to the beam splitting module 2, which then transmits it to the imaging module 1. The imaging module 1 performs synchronous scanning measurements of the first beam 51 and the second beam 52. Specifically, the beam splitting module 2 and the imaging module 1 are arranged sequentially along the input direction of the laser 5. The optical path adjustment module 3 is located below the imaging module 1. The laser 5 is transmitted from the input direction to the beam splitting module 2, which splits the laser 5 into a first beam 51 and a second beam 52. The first beam 51 is transmitted to the imaging module 1, enabling the imaging module 1 to acquire an image of the laser 5 in the near field. The second beam 52 is transmitted to the optical path adjustment module 3 below, where it is reflected back to the beam splitting module 2. It is then transmitted back to the imaging module 1 through the beam splitting module 2, enabling the imaging module 1 to acquire an image of the laser 5 in the far field. The optical path adjustment module 3 can adjust the optical path of the second beam 52 according to actual needs, thereby adjusting the distance between the near and far fields of the laser 5.

[0037] This invention uses a beam splitting module 2 to split the laser 5 into a first beam 51 and a second beam 52. The second beam 52 is then folded back onto the beam splitting module 2 via an optical path adjustment module 3. The beam splitting module 2 transmits the first beam 51 and the second beam 52 to an imaging module 1, allowing the imaging module 1 to simultaneously measure the near and far field parameters of the laser 5, improving measurement efficiency and time synchronization. Simultaneously, the optical path adjustment module 3 can adjust the optical path of the second beam 52, thereby adjusting the distance between the near and far fields of the laser 5.

[0038] As an optional implementation method, such as Figure 3As shown, the beam splitting module 2 includes a beam splitting element 21, a first reflector 22, a light-shielding plate assembly 23, and an assembly structure 24. The beam splitting element 21, the first reflector 22, and the light-shielding plate assembly 23 are all fixed on the assembly structure 24. The beam splitting element 21 is positioned above the light-shielding plate assembly 23, and the first reflector 22 is positioned below the light-shielding plate assembly 23. The light-shielding plate assembly 23 is used to isolate the field of view between the beam splitting element 21 and the first reflector 22. Specifically, the beam splitting element 21 can be a beam splitter. Both the beam splitting element 21 and the first reflector 22 are tilted at an angle of 45° relative to the horizontal plane. The beam splitting element 21 can split the laser beam 51 into a horizontal first beam 51 and a vertical second beam 52. The horizontal first beam 51 can directly illuminate the imaging module 1. The first reflector 22 can reflect the vertical second beam 52, which is reflected back by the optical path adjustment module 3, into a horizontal beam and illuminate the imaging module 1. The light-shielding plate assembly 23 isolates the field of view between the beam splitter 21 and the first reflector 22, avoiding interference between the field of view between the beam splitter 21 and the first reflector 22, and ensuring the accuracy of the detection by the imaging module 1.

[0039] More specifically, the light-shielding assembly 23 includes a first light-shielding plate, a second light-shielding plate, and a third light-shielding plate. The first light-shielding plate is laterally disposed between the lower end of the beam-splitting element 21 and the upper end of the first reflector 22. The second light-shielding plate is laterally disposed at the first end of the first light-shielding plate, and the second light-shielding plate and the first light-shielding plate are on the same horizontal plane. The third light-shielding plate is disposed below the second end of the first light-shielding plate, and the third light-shielding plate is perpendicular to the first light-shielding plate. The first and second light-shielding plates are used to isolate the first light-emitting direction of the beam-splitting element 21 and the light-emitting direction of the first reflector 22, and the third light-shielding plate is used to isolate the second light-emitting direction of the beam-splitting element 21 and the light-incident direction of the first reflector 22. Furthermore, the first and second light-shielding plates can be integrated into one structure, or the first and third light-shielding plates can be integrated into one structure. The configuration of the light-shielding assembly 23 can be adapted to actual needs.

[0040] As an optional implementation method, such as Figure 4As shown, the assembly structure 24 includes a first through-hole structure 241, a second through-hole structure 242, a third through-hole structure 243, a first mounting groove 244, a second mounting groove 245, and a third mounting groove 246. The first end of the first through-hole structure 241 is located in the input direction of the laser 5, and the second end of the first through-hole is correspondingly positioned with respect to the imaging module 1. The first end of the second through-hole structure 242 is located in the light-incident direction of the optical path adjustment module 3, and the first end of the third through-hole structure 243 is located in the light-out direction of the optical path adjustment module 3. The first mounting groove 244 is used to fix the beam splitter 21, the second mounting groove 245 is used to fix the first reflector 22, and the third mounting groove 246 is used to fix the light-shielding plate assembly 23. Specifically, laser 5 enters the first end of the first through-hole structure 241 from the input direction and is transmitted to the beam splitting component. The beam splitting component splits laser 5 into a first beam 51 and a second beam 52. The first beam 51 is output from the second end of the first through-hole structure 241 and transmitted to the upper region of the image sensor 11 (as described below). The second beam 52 is output from the first end of the second through-hole structure 242 and transmitted to the optical path adjustment module 3. The optical path adjustment module 3 reflects the received second beam 52 back and transmits it to the first end of the third through-hole structure 243. Through the third through-hole structure 243, it is transmitted to the first reflector 22. The first reflector 22 outputs the received second beam 52 after reflection through the second end of the first through-hole structure 241 and transmits it to the lower region of the image sensor 11 (as described below). The first mounting slot 244, the second mounting slot 245, and the third mounting slot 246 are all disposed on the first side (i.e., the front side) and the second side (i.e., the rear side) symmetrically on the assembly structure 24. The dimensions of the first mounting slot 244 match the dimensions of the beam splitter assembly, and the first mounting slot 244 corresponds to the position of the beam splitter assembly. The beam splitter assembly can be inserted into the first mounting slot 244, and its two ends are fixed by the first and second sides of the assembly structure 24. The dimensions of the second mounting slot 245 match the dimensions of the first reflector 22, and the second mounting slot 245 corresponds to the position of the first reflector 22. The first reflector 22 can be inserted into the second mounting slot 245, and its two ends are fixed by the first and second sides of the assembly structure 24. The dimensions of each slot in the third mounting slot 246 match the dimensions of each light-shielding piece in the light-shielding plate assembly 23, and the third mounting slot 246 corresponds to the position of the light-shielding plate assembly 23. Each light-shielding piece in the light-shielding plate assembly 23 can be inserted into the corresponding slot in the third mounting slot 246, and its two ends are fixed by the first and second sides of the assembly structure 24.

[0041] As an optional implementation method, such as Figure 4As shown, the four inner walls of the assembly structure 24 are all serrated. Specifically, the four inner walls of the assembly structure 24 (i.e., the front inner wall, the rear inner wall, the upper inner wall, and the lower inner wall) are all serrated to prevent stray light. The size and number of serrations can be adapted to actual needs.

[0042] As an optional implementation method, such as Figure 2 As shown, the imaging module 1 includes an image sensor 11 and a camera 12. The image sensor 11 is fixed on the first side of the camera 12, and the image sensor 11 is correspondingly positioned at the second end of the first through-hole structure 241. Specifically, the image sensor 11 is fixed on the first side of the camera 12 so that it can receive the first beam 51 and the second beam 52 output through the second end of the first through-hole structure 241. The image sensor 11 converts the received first beam 51 and the second beam 52 into a first electrical signal and a second electrical signal that are proportional to the beams, and transmits them to the camera 12. The camera 12 processes the received first electrical signal and the second electrical signal and generates an image to obtain an image of the near and far fields of the laser 5. This image is used to analyze the near and far fields of the laser 5 and to detect the laser 5.

[0043] As an optional implementation, the field of view of the image sensor 11 can be divided into an upper region and a lower region by the light-shielding assembly 23. Specifically, the plane containing the first and second light-shielding plates of the light-shielding assembly 23 can be located at half the height of the image sensor 11, dividing the image sensor 11 into an upper and lower region with an area ratio of 1:1. It should be noted that the positions of the beam-splitting element 21 and the first reflector 22 can be adaptively adjusted according to the setting position of the light-shielding assembly 23, ensuring that the relative positional relationship between the beam-splitting element 21 and the first reflector 22 and the light-shielding assembly 23 remains unchanged. Furthermore, since the near-field distance of the laser 5 is small, the detection deviation is also small. The plane containing the first and second light-shielding plates of the light-shielding assembly 23 can be set at three-fifths of the height of the image sensor 11, making the area ratio of the upper and lower regions of the image sensor 11 2:3. The plane containing the first and second light-shielding plates of the light-shielding assembly 23 can flexibly divide the upper and lower regions of the image sensor 11.

[0044] As an optional implementation method, such as Figure 2 and Figure 3As shown, the optical path adjustment module 3 includes a backlight reflection component 31 and a mounting base 32. The backlight reflection component 31 includes a second reflector 311 and a third reflector 312. The mounting base 32 includes a first groove 321 and a second groove 322. The first groove 321 is located on the top of the mounting base 32, and the backlight reflection component 31 is fixed on the first groove 321. The plane where the second reflector 311 is located is perpendicular to the plane where the third reflector 312 is located. The light incident direction of the second reflector 311 is located in the light emitting direction of the beam splitter 21, and the light incident direction of the third reflector 312 is located in the light emitting direction of the second reflector 311. The light emitting direction of the third reflector 312 is located in the light incident direction of the first reflector 22. The second groove 322 is located on the first side of the mounting base 32, and the mounting base 32 is movably connected to the housing 4 through the second groove 322. Specifically, the second beam 52 split by the beam splitter 21 is transmitted to the second reflector 311, which reflects the second beam 52 to the third reflector 312. The third reflector 312 then reflects the received second beam 52 back to the first reflector 22 of the beam splitter module 2, and finally reflects it to the lower region of the image sensor 11. Both the second and third reflectors 311 and 312 are tilted and their planes are perpendicular to each other. The plane of the second reflector 311 is perpendicular to the plane of the third reflector 312. The light-incident direction of the second reflector 311 is located in the light-outceasing direction of the beam splitter 21, the light-incident direction of the third reflector 312 is located in the light-outceasing direction of the second reflector 311, and the light-outceasing direction of the third reflector 312 is located in the light-incident direction of the first reflector 22. This allows the vertically oriented second beam 52 split by the beam splitter 21 to be vertically folded back onto the first reflector 22. The fixed base 32 is movably connected to the housing 4 through the second groove 322, so that the fixed base 32 can move up and down on the housing 4, thereby adjusting the optical path of the second beam 52 and realizing the adjustment of the distance between the near and far fields of the laser 5.

[0045] In addition, the backlight reflection component 31 can be set as a backlight reflector, which directly reflects the second beam back to the first reflector 22 of the beam splitter module 2. The top of the fixing base 32 corresponding to the backlight reflector does not need to be provided with the first groove 321.

[0046] As an optional implementation method, such as Figure 2As shown, the housing 4 includes a first outer shell 41, a second outer shell 42, and side plates 43. The first outer shell 41 and the second outer shell 42 are fixedly connected to form a receiving cavity, which is used to accommodate the imaging module 1, the beam splitting module 2, and the optical path adjustment module 3. The side plates 43 are disposed on both sides of the receiving cavity and are fixedly connected to the first outer shell 41 and the second outer shell 42. Specifically, the upper end of the first outer shell 41 is used to fix the imaging module 1, the upper end of the second outer shell 42 is used to fix the beam splitting module 2, and the lower ends of the first outer shell 41 and the lower ends of the second outer shell 42 are used to clamp and fix the optical path adjustment module 3. The side plates 43 are disposed on both sides of the receiving cavity, which can cover the imaging module 1, the beam splitting module 2, and the optical path adjustment module 3 contained in the receiving cavity, protect the imaging module 1, the beam splitting module 2, and the optical path adjustment module 3, and improve the service life of the laser imaging device.

[0047] As an optional implementation method, such as Figure 2 As shown, the first housing 41 includes a mounting hole 411, a protrusion 412, and at least one elongated through hole 413. The mounting hole 411 is located at the upper end of the first housing 41 and corresponds to the camera 12. The mounting hole 411 allows the transmission head 121 of the camera 12 to pass through the first housing 41. The protrusion 412 and the elongated through hole 413 are both located at the lower end of the first housing 41. The protrusion 412 corresponds to and matches the second groove 322, and the elongated through hole 413 corresponds to the fixing hole on the fixing base 32. The second housing 42 is provided with a light inlet hole 421, which corresponds to the beam splitting module 2. Specifically, the transmission head 121 of the camera 12 (such as a USB connector) can pass through the mounting hole 411 and exit the housing 4, facilitating the connection of the camera 12 to the terminal device and the transmission of detected data. The protrusion 412 corresponds to and matches the second groove 322. The fixing seat 32 can be engaged with the protrusion 412 through the second groove 322, and the protrusion 412 and the second groove 322 are in clearance fit. The fixing seat 32 can move up and down along the protrusion 412, thereby adjusting the optical path of the second beam 52. There are two elongated through holes 413, which are respectively set on both sides of the protrusion 412. Fasteners (such as bolts or screws) can pass through the elongated through holes 413 and into the fixing holes on the fixing seat 32, thereby locking and fixing the fixing seat 32. The fasteners can fix the fixing seat 32 by passing through the corresponding position of the elongated through holes 413 according to the position of the fixing holes of the fixing seat 32. The light inlet hole 421 on the second housing 42 is set corresponding to the first end of the first through hole structure 241, ensuring that the laser 5 can be input into the beam splitting module 2 through the light inlet hole 421.

[0048] More specifically, the protrusion 412 can be set as a slide rail, and the second groove 322 of the fixed seat 32 can be movably connected to the slide by a slider.

[0049] like Figure 5As shown, the laser imaging device of this application is applied to the transmitting module 6 to perform near-field and far-field measurements on the laser emitted by the transmitting module 6. The transmitting module 6 includes an adjustment stage 61, a connector 62, and a collimator 63. The collimator 63 is fixedly connected to the adjustment stage 61 via the connector 62. The collimator 63 is correspondingly arranged with the light entrance aperture 421. The adjustment stage 61 is used to drive the collimator 63 to move in the X, Y, and Z directions, and to drive the collimator 63 to rotate in the X, Y, and Z directions. Specifically, the adjustment stage 61 can be a manual adjustment stage 61 or an automatic adjustment stage 61. The adjustment stage 61 can adjust the six degrees of freedom of the collimator 63, thereby adjusting the direction of the collimator 63 so that the collimator 63 can be aligned with the light entrance aperture 421, ensuring that the laser 5 output by the collimator 63 can enter the beam splitting module 2 through the light entrance aperture 421.

Furthermore, under the teachings of the present utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present utility model.
