Abstract

The invention discloses a ring laser electrode indium seal quality detecting method and system. The system comprises a linearly polarized light source and a polarized light imaging mechanism, linearlypolarized light generated by the linearly polarized light source is obliquely incident into a glass cavity to be irradiated to an interface of the glass cavity and an indium ring, mixed reflected light is formed, the mixed reflected light is imaged by a polarized light imaging mechanism, a polarized light imaging system includes a quarter wave plate, an polarization analyzer and an industrial CCDcamera, and the quarter wave plate and the polarization analyzer can effectively filter the reflected light generated by the glass cavity and only allow the reflected light in an indium ring region to be imaged. The ring laser electrode indium seal quality detecting system eliminates the stray reflected light on the surface of the glass cavity, increases the contrast of imaging of the indium ring, makes the sealing connecting defects be easier to observe, and improves the indium ring detection quality.

Description

technical field [0001] The invention relates to the field of ring laser manufacturing, in particular to a technology for detecting the quality of ring laser electrode indium seals. Background technique [0002] Ring lasers are standard light sources widely used in high-precision optical metrology instruments, such as laser gyroscopes. The laser gyroscope is a high-precision photoelectric inertial sensing element that has achieved fruitful practical applications in the field of inertial technology, and is widely used in inertial navigation systems on aircraft, rockets and tanks. [0003] Ring lasers usually use quartz glass or glass-ceramic as the resonant cavity of the laser. The cavity is drilled with a light-through hole, and the reflector and the cavity are airtightly mounted at the vertices of the polygon by optical glue to form a polygonal closed-loop optical path. A cathode and two anodes are installed on the cavity, using the clear hole in the cavity as a laser gain...
