A laser illuminator base for fine-tuning the light axis

Abstract

The base of the laser illuminator for fine-tuning the optical axis of the light output of the present invention includes an illuminator bracket, an upper adapter plate, a lower adapter plate, a fixed base plate, a pitch adjustment motor and a horizontal adjustment motor, and the connection between the lower adapter plate and the upper adapter plate A pitch adjustment support and a support ball are arranged between them, and a pitch adjustment screw engaged with the turbine part is fixed on the output shaft of the pitch adjustment motor; through the rotation of the pitch adjustment motor, the upper adapter plate can be driven to pitch around the support ball; The output shaft of the adjustment motor is fixed with a horizontal adjustment screw meshed with the horizontal adjustment sector wheel; through the rotation of the horizontal adjustment motor, the lower adapter plate can be driven to rotate in the horizontal plane. The laser illuminator base of the present invention effectively solves the phenomenon that the center of the minimum spot and the center of the minimum field of view lose alignment and concentricity after manual alignment adjustment at the factory, transportation and installation, thereby effectively reducing the cost of later maintenance and use.

Description

Technical field [0001] The invention relates to a laser illuminator base that is convenient for fine-tuning the optical axis of light, more specifically, it particularly relates to a laser illuminator base that is easy to realize pitch and horizontal rotation adjustment and is convenient for fine-tuning the optical axis of light. Background technique [0002] Since there is a certain interval between the illuminator and the imaging lens of the laser night vision device, the two optical axis centers are independent and separated at the minimum field of view and minimum illumination angle, so there will be an illumination spot center and an imaging field of view The problem of center alignment does not overlap, which requires alignment. [0003] The existing laser night vision illuminator, when its minimum illumination angle is matched with the minimum field of view of the imaging device, the center of the spot and the center of the imaging field of view are aligned manually. At pres...

AI Technical Summary

Problems solved by technology

This kind of solution, the patent document also has the example of electric adjustment "A Device for Alignment" authorization announcement number 203324584U, but the structure of this solution is complicated, similar to a small pan-tilt, and it is not practical

[0004] Since the installation of the laser night vision device is carried out during the day, and the alignment of the minimum spot of the laser illuminator and the minimum field of view angle of the imaging cannot be observed during the day, it is impossible to power on the inspection after the installation is completed.

And usually these night vision devices have to be hoisted or installed in a high place that is not easy to reach. Therefore, when the installation is completed and the misalignment is found at night, it is necessary to climb to the position of the rack again for debugging, and it can only be debugged at night. In order to observe the spot

The installation and use of night vision devices is very inconvenient, especially for traffic monitoring. For example, night work on expressways is not allowed. This requires that the night vision devices be checked one by one before installation. Alignment verification adjustment to detect misalignment due to handling

Although the adjustment can be checked before installation, there is no guarantee that the misalignment of the light spot and field of view will not occur during the installation process. Once the installation is completed, if there is a deviation between the light spot and the field of view, it needs to be disassembled during the day and adjusted at night. , and then wait for the day to install

Such installation and commissioning work is time-consuming and laborious, and will increase a lot of costs, which is not conducive to the large-scale promotion and application of equipment
