摘要： A high speed optical analog/digital conversion process with a simple configuration, in which an optical-pulse branching delay multiplexer generates as many duplicates of each optical pulse as the predetermined number of bits by branching each optical pulse string obtained by sampling an input optical analog signal, and generates a temporally consecutive optical pulse string by multiplexing the duplicated optical pulses with a predetermined intensity difference and time difference. An optical encoder and an optical-threshold processing unit perform an encoding and a quantization of an optical pulse string, and output an optical digital signal corresponding to the optical analog signal.

摘要： A photoimaging material which comprises a support and a photoimaging layer formed on the support. The photoimaging layer comprises microcapsules and a reducing agent present outside the microcapsules. The microcapsules contain a leuco dye capable of oxidative color formation, a photooxidizing agent and an organosulfur antioxidant. The reducing agent is 2,2′-methylenebis(4-methyl-6-t-butylphenol) or 2,2′-methylenebis(4-ethyl-6-t-butylphenol). The photoimaging material is capable of thermal image fixing based on a method of forming color by radical oxidation of various leuco dyes to the corresponding dyes with a photooxidizing agent. The photoimaging material is not prone to background coloring (fogging) during storage under dark or light conditions after image fixing, and does not foul the inside of the apparatus during thermal image fixing.
