Embodiment

[0070] A laser with a wavelength of 632.8nm and a power of 2mW is incident on the light source, and the laser is used to actually measure the spectral spot:

[0071] (1) Adjust the table top of the optical table to ensure that the surface of the optical table meets the required accuracy, install mirrors on the optical tables on both sides, pay attention to keep the height of the mirrors consistent, and place a crosshair in the center of the mirror.

[0072] (2) Install the optical translation guide rail, and install the electric rotary table on the translation table. During the installation process, ensure that the table is horizontal during the translation and rotation process. Start the electric translation platform to make the electric translation platform start to move. Take 6 points on the entire stroke. If the offset of the crosshair at these 6 points has a linear relationship with the displacement, the linear guide has been adjusted.

[0073] (3) Install the laser on th...

Abstract

The invention relates to a laser beam long-distance transmission characteristic parameter test system and a working process thereof. Laser signals in the atmosphere are tested by utilizing advantagesof a photoelectric digital technology and an automatic control technology, so that the performance parameters of the laser at different transmission distances can be tested. According to the system, the platform surface of an optical platform serves as a reference surface of the whole system, the optical axis plane height of the optical system is determined, and a laser and a test piece are installed on a test piece clamping platform; the emitted light beams are incident to the center positions of reflectors through small holes in a target, and the angles of the reflectors are adjusted, so that the light rays are deflected and then reflected by a plurality of reflectors in sequence, and the light rays form an optical network plane; and the light rays are finally reflected from the oppositeposition of the same side of the optical platform and are incident on the center of the solid target to form an optical system.

Description

technical field [0001] The invention relates to a characteristic parameter test system for long-distance transmission of laser beams and its working process. Background technique [0002] With the rapid development of modern optical technologies such as laser, infrared, television and low light, photoelectric technology has been widely used in detection, fire control, navigation, guidance, command, control and other fields, making intelligent systems or modern weapons even more powerful. But the ensuing laser interference is also becoming more and more prominent in the photoelectric system, and photoelectric countermeasures are increasingly valued by people; laser interference refers to the strong laser energy emitted by the laser irradiating the photoelectric sensor or optical system, resulting in loss of working ability . The strong laser beam on the target will change the characteristics and state of the target's constituent materials, causing irreversible damage such as...
