Extension of the velocity detection range of a tracking novelty filter that uses LiNbO(3) and strontium barium niobate.
A method for extending the velocity range of motion detection by an optical tracking novelty filter is described. Separate photorefractive crystals are used as phase-conjugate mirrors in a phase-conjugate Michelson interferometer. Such an arrangement can ensure a significant difference in response times between the two arms of the interferometer, so that the range of detectable velocity is greatly reduced. Also, this implementation of a tracking novelty filter does not require a lossless dielectric beam splitter.
