We report on the construction of a matching information terminal based on a spatially coded moiré technique, to be used as visualization equipment for genome analysis. The terminal provides the result of a string matching operation, which is achieved by overlapping of spatially coded patterns with a small intersection angle to generate moiré fringes. The fringes reveal the matching between two string sequences coded as spatial patterns. Due to its flexibility in image display, the matching information terminal is able to deal with long strings such as a gene sequence. The constructed terminal achieves string matching for 256 bases of DNA sequences and displays about 25,000 point-to-point matching results at a time.
