Abstract
Composite filters offer one solution to the problem of scanning numerous filters to find a single target at any aspect, orientation, or configuration. Many different techniques for generating composite filters exist, each with their own advantages and disadvantages. Liquid crystal televisions are an increasingly popular choice for spatial light modulators and are characterized by a coupled phase and amplitude response. The coupled response can cause a problem if not accounted for, however, it can also be used to more closely approximate the desired filter response. This paper will present the results of using optimally encoded composite filters on a LCTV for optical pattern recognition applications.
