Real Time Correlating Operation on Diffuse Objects,
Abstract
Real time correlating operations on diffuse objects are an expansion and outgrowth on 2-D transparent objects. A real time optical correlator with two transparent pieces is made using photorefractive crystal Bi12SiO20 (BSO) and noncrystal membrane As2S3 as recording media (1-3). Due to the absence of wave filter that is associated with the typical real time optical correlator, this enables the two transparent pieces to have real time correlation and have potential applications in feature recognition. However, test object and reference object have to be in transparent state. In reality, most objects that need to be recognized tend to be diffuse objects, or they have to rely on natural light (incoherent light) for lightening. The realization of real time correlation on two diffuse objects or incoherent light images remains to be fulfilled. (MM)
