Paper Abstract

Brightness, S/1,4 and contrast of an image reconstructed from a rainbow hologram. using Agfa-Gevaert 8E56HD and Shipley MICROPOSIT-1350 (called AZ-1350 before.) photoresist are studied changing signal to reference ratio, exposure, dilution ratio of AZ-303A developer and its developing time. It is found that a qualified image can be obtained when signal to reference ratio is from 1:6 to 1:12 and the dilution ratio of AZ-303A developer is 1:5.
