Optical feature extraction apparatus and encoding method for detection of DNA sequences

摘要

The invention is an optical feature extraction apparatus which uses video display, spatial light modulation, and detection components in conjunction with microlenslet replicating optics, to expedite the recognition of DNA sequences based on their symmetry properties and, specifically, to classify short (6 bases in length) sequences of DNA as palindrome or nonpalindrome. The DNA sequences are symbolically encoded using a novel method. Multichannel operation is achieved through the replication of input scenery, making possible a higher throughput rate than for single channel systems.
