Abstract
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.
Claims12
An optical feature extraction apparatus for detecting data comprising:
- a filter for decoding the data to be detected comprising a plurality of opaque and transparent regions;
- a display means for displaying the filter, the displayed filter spatially modulating the light from the display means and creating an intensity distribution of light;
- a means for replicating the light intensity distribution received from the display means;
- a mask encoded with the data to be classified, the mask receiving and further modulating the light intensity distribution;
- and
- a means for detecting the further modulated light intensity distribution received from the mask.
