Abstract
Based on the principles of real-time monitoring photothermoplastic holography, a practical photothermoplastic holographic recording instrument has been built up by using residual-heat andslow-heating method.The system consists of a DC high voltage power source and a AC low voltage Power source for charging sensitization and ohmic heating of the photothermoplastic plate,a corona-chargedevice, a copper grid and a transparent conductive plate. Especially,the corona-charge device has thefeatures of compact,transparent, uniform of charging density and easy to operate.The instrument cantake the high quality holograms for high diffraction efficient and high SNR of the system.This paper introduces the operation principle, structure and performances of the instrument.
