Paper Abstract

A optical system to get the wavelet transform coefficient which needed in encoding system is discussed in our paper. A reference beam was used in our system to get the positive or negative information of the signal. An reconstruction based on the signal proved the feasibility and reliability of our system. Some problems are discussed in the end of this paper.
