Abstract： |
The present invention relates to a laser transverse film demonstration system based on can''s eye cavity reflector loss modulation, belonging to the field of helium neon laser experimental device technology. It successively includes computer, CCD image acquisition system, semi-external cavity He-Ne laser tube convex lens and its holding regulation device and concave lens and its holding regulation device, in which the focal length of said convex lens is equal to curvature radius of concave lens, and equal to the distance between two holding regulation devices and is formed into cat''s eye reverser the CCD image acquisition system can be used for collecting laser beam transverse film pattern and utilizing video line to input the laser beam transverse film pattern into computer, the image acquisition card in the computer can be used for making acquisition and image formation, and said image can be displayed and stored. |
