Abstract: In this paper,a new type real-time automatic processing device has been developed for hologram negatives.Eliminating the traditional visual mode,this device,equiped with a computer-controlled small vehicle,uses the principles of infrared photoelectricty to identify the negative density,which makes it possible to completely automate the technological processes under darkroom conditions and hence greatly improve the product quality.This will,no doubt,stimulate a wider application of the real-time method in the lasser holometry.
