Abstract
A method is disclosed by which filters are created optically in real time—and tested. This technique is made possible by recent advances in Charge Couple Detector (CCD) detector array technology. Pixel (picture element) size has decreased to the point that real fringes can be detected and displayed. The fringes result from the interference of the optical Fourier transform of a displayed scene with a specified plane wave. Phase information is thus preserved. This is the critical information required in producing a hologram or a holographic matched filter.
