Description

Technical Field

[0001] This utility model belongs to the field of optoelectronic instrument manufacturing technology, specifically relating to a calibration device for a periscope-type observation aiming scope integrated testing instrument. Background Technology

[0002] With the rapid development of optoelectronic technology, various new optoelectronic instruments are widely used in the national defense and military fields. Among them, the periscope observation and aiming scope (hereinafter referred to as "periscope observation and aiming scope") is a core observation and aiming component of vehicles, artillery and other equipment. Its production and assembly process relies on the periscope observation and aiming scope integrated testing instrument (hereinafter referred to as "integrated instrument") for performance testing and debugging.

[0003] However, the current verification or calibration of integrated instruments still uses outdated techniques: a calibration system is built by replicating the structure of a periscope sight and using a square tube front sight. This method has the following drawbacks: 1. Cumbersome operation: The assembly and adjustment of the frame and the square tube front sight rely on repeated manual adjustments, which is complex and inefficient; 2. Poor operating comfort: The operator must visually observe the alignment of the reticle throughout the process, which can easily lead to visual fatigue during long periods of work; 3. Limited calibration accuracy: Subjective judgment by the human eye is prone to error, and the reference stability of the old frame is insufficient, making it difficult to meet the high-precision calibration requirements of new integrated instruments.

[0004] Given the core role of periscopes in national defense equipment and the necessity of periodic calibration of integrated instruments, the development of an efficient, comfortable, and high-precision integrated instrument calibration device has become an urgent need in the field of optoelectronic instrument manufacturing. Utility Model Content

[0005] To address the aforementioned deficiencies in the existing technology, this utility model provides a calibration device for a periscope-type observation aiming scope integrated testing instrument. This device is used to verify or calibrate the parallelism between the collimator and the optical axis of the measuring front mirror in the periscope-type observation aiming scope integrated testing instrument. It includes a receiving component and a display component. The receiving component is integrated into a closed housing. The bottom of the closed housing is provided with three mutually perpendicular reference surfaces, namely the front side, the bottom surface, and the left side surface. The perpendicularity between the three reference surfaces is 1′.

[0006] The receiving component includes collimator A, collimator B, a photoelectric receiver, and a wireless transmitter. Collimator A and collimator B are located on the left and right sides of the enclosed enclosure, respectively. Collimator A is higher than collimator B, with a certain height difference between them. The optical axes of collimator A and collimator B are parallel to each other and are parallel to the bottom and front sides of the enclosed enclosure. At the same time, collimator A and collimator B are both perpendicular to the left side. The photoelectric receiver is electrically connected to the wireless transmitter and is used to collect the reticle signals received by collimator A and collimator B and convert the reticle signals into wireless signals for output. The collimator A, collimator B, photoelectric receiver, and wireless transmitter are integrated together using existing mechanical components.

[0007] The display components include a wireless receiver and a display. The wireless receiver establishes a wireless communication connection with the wireless transmitter to receive wireless signals and transmit them to the display. The display is used to synchronously display two sets of détachable images.

[0008] Optionally, the two sets of reticles include reticle A and reticle B, where reticle A is the collimator reticle of the periscope sight integrated testing instrument being calibrated and the reticle of collimator A, and reticle B is the front mirror reticle of the periscope sight integrated testing instrument being calibrated and the reticle of collimator B.

[0009] Optionally, the dimensions of the bottom surface of the enclosed enclosure are 200mm × 300mm × 20mm.

[0010] Optionally, the focal length of both collimator A and collimator B is 120mm.

[0011] Optionally, the effective communication distance between the wireless transmitter and the wireless receiver is ≥1m.

[0012] Optionally, the photoelectric receiving device is a CCD image sensor, and the resolution of the display is not less than 1920×1080 pixels.

[0013] This invention also includes other components that enable the calibration device of a periscope-type observation aiming scope integrated testing instrument to function properly, all of which are conventional techniques in the art. Furthermore, any devices or components not specified in this invention employ conventional techniques in the art, such as collimator A, collimator B, photoelectric receiver, wireless transmitter, wireless receiver, and display.

[0014] The working principle of this utility model is as follows: First, the enclosed housing of the receiving component is fixed by a reference surface to ensure the stability of the device reference; then, the position of the calibrated instrument is adjusted so that its measuring components (parallel light tube and measuring front mirror) are aligned with parallel light tube A and parallel light tube B of this device, respectively; then, the device is started, and the photoelectric receiving device collects the reticle signals received by parallel light tube A and parallel light tube B, and transmits them to the display component through the wireless transmitting device; finally, after receiving the signal, the wireless receiving device transmits it to the display, and the operator judges the parallelism of the two optical axes of the calibrated instrument by observing the alignment of the two sets of reticles in screen A and screen B, thus completing the calibration or verification.

[0015] The beneficial effects of this utility model are:

[0016] (1) High security: The receiving component and the display component use wireless communication, which eliminates safety hazards such as equipment collision and line damage caused by wire pulling, making the device more reliable in operation;

[0017] (2) Excellent operational comfort: The display screen is used to replace direct observation by the human eye, which avoids visual fatigue of operators for a long time and improves the work experience;

[0018] (3) High calibration accuracy: By using the high-precision reference surface (perpendicularity of 1′) of the enclosed box and the precise adjustment of the collimator (optical axis parallel), combined with the objective acquisition of photoelectric signals, subjective errors of the human eye are reduced, and calibration accuracy is significantly improved.

[0019] (4) Broad application prospects: It is applicable to vehicles, artillery and other equipment with periscope sights in various equipment in the national defense and military fields. It can meet the periodic calibration needs of integrated instruments in factory production. The market demand is stable and the economic benefits are considerable. Attached Figure Description

[0030] 3. Mechanical components: Select brackets, fasteners, etc. for fixing collimators and functional devices, and choose aluminum alloy as the material (to balance lightweight and stability).

[0031] (II) Fabrication of the reference plane and enclosed enclosure

[0032] 1. Make a base 2 with a reference surface: use stainless steel to process a 200mm×300mm×20mm cuboid structure, which serves as the bottom reference of the enclosed box 1;

[0033] 2. Reference surface machining: Precision milling is performed on the front side, bottom side, and left side of the base to ensure that the three sides are perpendicular to each other, with a perpendicularity error of ≤1′ (which can be detected by a laser interferometer);

[0034] 3. Enclosed housing assembly: Based on the base, an enclosed housing is formed by welding aluminum alloy plates (only the light transmission window of the collimator objective lens 5 is retained), and space is reserved inside the housing for the installation of components.

[0035] (III) Assembly and Calibration of Receiver Components

[0036] 1. Component fixing: according to Figure 1At the locations shown, collimator A, collimator B, photoelectric receiver, and wireless transmitter are fixed in a closed box using mechanical brackets; the photosensitive surface of the photoelectric receiver is aligned with the exit pupils of the two collimators to ensure complete acquisition of the reticle signal.

[0037] 2. Optical axis adjustment: Using conventional optical axis adjustment tools in this field (such as an autocollimator), adjust the posture of the two collimators so that collimator A is higher than collimator B by a certain distance, and make the two optical axes parallel to each other, and both parallel to the bottom surface reference and the front side reference of the base; after the adjustment is completed, lock the position of the collimators with fasteners.

[0038] 3. Circuit connection: Connect the signal output terminal of the photoelectric receiver to the signal input terminal of the wireless transmitter through a wire (the wire should be shielded to reduce interference), install the transmitting antenna 6, and configure a DC power supply (12V voltage, which meets the normal working requirements) for each device.

[0039] (iv) Display component assembly

[0040] according to Figure 2 As shown, the wireless receiver is connected to the display via a wire to ensure that the signal received by the wireless receiver can be transmitted to the display in real time; an independent DC power supply (12V voltage) is configured for the display component, and receiving antenna 8 is installed to ensure signal reception sensitivity.

[0041] (V) Device Commissioning and Verification

[0042] 1. Wireless communication test: Place the receiving component and the display component within a 1m range, turn on the power, and verify the stability of wireless transmission and reception (no signal interruption, delay ≤100ms);

[0043] 2. Reticle display test: Using a standard calibration kit (a simulated instrument with known optical axis parallelism), verify whether the monitor can clearly display "Image A" and "Image B", and the reticle alignment error is ≤0.1′ (verified by the known error of the standard calibration kit);

[0044] 3. Reference stability test: After the device is left to stand for 24 hours, the perpendicularity of the base reference surface and the parallelism of the optical axis of the collimator are retested. The error change is ≤0.05′ to ensure the reference is stable.

[0045] (vi) Calibration Application Examples

[0046] Taking the calibration of the integrated instrument for a certain type of vehicle periscope sight as an example:

[0047] 1. Fix the receiving component of this device to the optical platform via the base reference surface, ensuring that the reference surface is horizontal;

[0048] 2. Adjust the position of the calibrated instrument so that its measured collimator is aligned with collimator A of this device, and the measured front mirror is aligned with collimator B of this device;

[0049] 3. Start this device and the integrated instrument; the display will simultaneously show screen A and screen B.

[0050] 4. The operator observes the alignment of the two sets of reticles: if the reticles are completely aligned, it means that the parallelism of the two optical axes of the synthesizer is qualified; if there is a misalignment, adjust the synthesizer according to the misalignment until the reticles are aligned, and the calibration is completed.

[0051] The embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
