Paper Abstract

To take a large and high-grade hologram, have been numerous scientific workers' interested topics. Since the stability of the holographic plate, objective table's stability, object's stability, optical elements' stabilities, etc, aren't easily supervised and controlled precisely, the laser holographic technique has progressed at a slow pace. Precise micropressure measuring system, an application of laser technology, is introduced as a method for monitoring holographic plates' stability. This system firstly brings the pressure sensor into the laser holographic experiments, and uses the soft Kingview to design the programs for controlling the pressure sensor, so that the system can real-time monitoring and real-time adjusting the laser holographic plates' stability. Being verified by experiments, this experiment has achieved good results, for example, making a larger hologram, saving the time taken from the original 1-2 days to present of 0.5-1.5 hours, that is to say those above-mentioned measures raise the success rate of making large holograms to some extent.
