Abstract

It is an object of the present invention to fulfill optical analog/digital conversion process at high speed with a simple constitution comprising an optical pulse branching-delaying-wave combining unit 40, an optical encoder 60 and an optical threshold processor 70. The optical pulse branching-delaying-wave combining unit 40 branches respective optical pulse series S11 on which the inputted optical analog signal Sin has been sampled, generates the same number of duplicate of respective optical pulse as the specified bit number, gives the specified intensity difference and time difference to respective duplicate of optical pulse, combines the waves thereof, and generate-outputs time consecutive optical pulse series. The optical encoder 60 performs the encoding and quantizing of optical pulse series S12, and outputs the optical digital signal Sout corresponding to the optical analog signal Sin.
