Abstract

In order to study the influence of environment temperature variation on the quality of holographic images, the change of transmit path in the holographic optical system is analyzed for both objective beam and reference beam before and after mirror deformation. In theory, finite element analysis method is used to simulate the anti-three through seven mirror deformation at 27℃, 28℃ and 29℃. And a new real-time monitoring and displaying laser speckle system is designed for measuring ambient temperature and beam splitting mirror distortion detection. The deformation value measured in the experiment are 406nm, 420nm and 427nm respectively at the same temperature mentioned above. The results show that theoretical and experimental values are in good agreement, and errors are less than 0.5%.
