Abstract
Description
Technical Field
[0001] This utility model relates to the field of spectrometer technology, and in particular to an optomechanical integrated structure for a mapping imaging spectrometer. Background Technology
[0002] A mapping imaging spectrometer is an optomechanical integrated system that deeply integrates imaging and spectral technologies. It typically consists of an optical system, a detector array, a signal processing and data system, etc. In use, after the target radiation is collected, it forms a one-dimensional spatial strip image through a slit. At this time, the collimating lens converts the light into a parallel beam, and the prism decomposes it into multiple monochromatic beams according to wavelength. Then, the converging lens focuses the monochromatic light onto the receiving surface of the CCD sensor. The image information is transmitted to the FPGA for processing through the CCD sensor. Mapping imaging spectrometers are widely used in geological and mineral exploration, vegetation ecological monitoring, ocean and water color remote sensing and other scenarios.
[0003] While existing technologies enable the use of spectrometers, in practical applications, the heat generated by the CCD sensor is difficult to handle in a timely manner. Typically, the CCD sensor generates a certain amount of heat during the operation of a spectrometer, causing the module to dissipate heat solely through self-dissipation, thus affecting the module's detection performance. On the other hand, air can easily enter the machine body through the opening of the heat dissipation cavity. The heat dissipation cavity of the machine body is usually an open structure, which allows moisture in the air to enter the machine body when the machine body is not in use, thus affecting the lifespan of the machine body.
[0004] Therefore, this invention proposes an optomechanical integrated structure for a mapping imaging spectrometer. Utility Model Content
[0005] Based on this, in order to overcome the common problem that the heat generated by CCD sensors is difficult to handle in a timely manner, and that air can easily enter the body through the opening of the heat dissipation cavity, a solution was developed.
[0006] The technical solution of this utility model is as follows: an optomechanical integrated structure for a mapping imaging spectrometer, comprising a body, a heat dissipation cavity provided on one side of the body, a working cavity provided on the other side of the body, a partition fixedly provided inside the body between the heat dissipation cavity and the working cavity, the partition and the body being an integral structure, an installation cavity provided at the center of the partition, the installation cavity being a through structure, a heat-conducting plate fixedly provided on one side of the partition inside the heat dissipation cavity, and heat dissipation fins fixedly provided on one side of the heat-conducting plate, the heat dissipation fins being welded to the heat-conducting plate;
[0007] A drive motor is fixedly installed at the front and rear ends inside the heat dissipation cavity. A fan blade is fixedly installed on the outside of the output shaft of the drive motor. Air holes are provided inside the front and rear ends of the heat dissipation cavity of the machine body, and the air holes are located on the outside of the drive motor.
[0008] Preferably, the body has a slot located inside the air vent outside the slot. The slot has an open structure and is connected to the heat dissipation cavity through the air vent. A baffle plate is provided inside the slot, and the baffle plate is slidably engaged with the slot.
[0009] Preferably, the body has two through holes located both inside the slot front opening and above the shield, with the through holes on the body corresponding to the through holes on the shield.
[0010] Preferably, a pull rod is provided inside the through hole, one end of the pull rod extends to the outside of the machine body through the opening of the through hole, and a return spring is fixedly provided on the outside of the pull rod, with the other end of the return spring fixedly connected to the outer wall of the machine body.
[0011] Preferably, a CCD sensor is installed inside the mounting cavity. The CCD sensor is fixed to the partition plate by screws, and one end of the CCD sensor is in contact with the heat-conducting plate.
[0012] Preferably, a detection head is fixedly installed at the front end of the outer side of the body, one end of the detection head extends into the interior of the mounting cavity, an image mapper is fixedly installed inside the mounting cavity on one side of the detection head, a focusing lens is fixedly installed inside the mounting cavity between the image mapper and the detection head, a collimating lens is fixedly installed inside the mounting cavity at the rear end of the image mapper, a prism is installed inside the mounting cavity at the rear end of the collimating lens, and a microlens array is fixedly installed inside the mounting cavity on one side of the prism.
[0013] Preferably, an FPGA component is fixedly installed on the upper part of the outer side of the machine body, and network ports are provided on both sides of the FPGA component and the lower part of the machine body. Power interfaces are provided on the end of the FPGA component located on the side of the network port and the lower part of the machine body located in front of the network port.
[0014] The beneficial effects of this utility model are:
[0015] 1. The optomechanical integrated structure for the mapping imaging spectrometer accelerates heat dissipation from the CCD sensor through heat dissipation fins and fan blades during use. When the device is in use and the shielding plate has been replaced with a mesh filter plate, the heat on the CCD sensor is transferred to the heat dissipation fins through the heat conduction plate. The heat dissipation fins increase the contact area between the heat conduction plate and the air. At the same time, the operator can press the switch on the device to turn on the drive motor, which causes the output shaft of the drive motor to drive the fan blades to rotate. The rotation of the fan blades accelerates the airflow and enters the heat dissipation cavity through the slot and the air hole. The airflow blows towards the heat dissipation fins, and the heat is transferred to the airflow through thermal radiation. The airflow that has absorbed the heat is discharged from the heat dissipation cavity through the air hole at the other end, thereby improving the heat dissipation efficiency of the CCD sensor and preventing heat from accumulating on the CCD sensor for a long time.
[0016] 2. The optomechanical integrated structure for this mapping imaging spectrometer allows for the sealing of the vent openings via a shield and a pull rod. After use, the operator pulls the pull rod, disengaging one end from the through-hole on the filter plate, with the return spring in a stretched state. The operator then removes the filter plate from the slot, improving the flexibility of filter plate and shield replacement. The operator aligns the shield with the slot opening and inserts it, blocking the vent opening. After releasing the pull rod, the return spring's force moves the pull rod until one end passes through the through-hole on the shield, securing the shield and preventing moisture from entering the machine when idle, thus extending its lifespan.

[0029] The heat dissipation fins 9 are welded to the heat conduction plate 10. The installation method is based on existing welding methods and has not been improved, so it will not be described in detail here.

[0038] A detection head 2 is fixedly installed at the front end of the body 1. One end of the detection head 2 extends into the interior of the mounting cavity 12.

[0041] The network port 24 designed here can connect the FPGA component 22 and the CCD sensor 11 through a cable, and connect the FPGA component 22 to the back end through the network port 24.

[0042] Working principle: See Figure 1 , Figure 3 , Figure 4As shown, after the machine body 1 is used, the baffle plate 5 has been replaced with a filter plate. At this time, the heat on the CCD sensor 11 is transferred to the heat dissipation fins 9 through the heat conduction plate 10. At the same time, the operator can press the switch on the machine body 1 to turn on the drive motor 18, so that the output shaft of the drive motor 18 drives the fan blade 17 to rotate. The rotation of the fan blade 17 accelerates the air to form an airflow and enters the heat dissipation cavity 6 through the slot 3 and the opening of the air hole 16. At this time, the airflow blows towards the heat dissipation fins 9, and the heat is transferred to the airflow through thermal radiation. The airflow that has absorbed the heat is discharged from the heat dissipation cavity 6 through the air hole 16 at the other end.
[0043] See Figure 1 , Figures 3-5 As shown, after the machine body 1 is used, the operator pulls the lever 4, causing one end of the lever 4 to disengage from the through hole 20 on the filter plate, and the return spring 19 is in a stretched state. Then the operator removes the filter plate from the slot 3. At this time, the operator aligns the baffle plate 5 with the opening of the slot 3 and inserts it into the slot 3. The baffle plate 5 blocks the opening of the air hole 16. After the operator releases the lever 4, the return spring 19 drives the lever 4 to move by the force generated by the reset until one end of the lever 4 passes through the through hole 20 on the baffle plate 5, thus completing the fixation of the baffle plate 5.
[0044] It should be noted that the aforementioned drive motor 18 can be powered by existing operating techniques, whether using a power supply device or an external wire, both of which are conventional operating techniques and will not be described in detail here.
