Method for performing complex-valued linear operations on complex-valued data using incoherent light

Generation of continuous complex-valued functions for a joint transform correlator

“…We obtained the complex amplitude distribution over the output plane of the JTC by performing a FT of the expression in Eq. 4: (5) where we have used the hermitic property of the FT and the fact that the FT of F*H equals [f * h](x, y).…”

“…The decomposition of a complex function into positive-valued functions has been proposed in the past for incoherent processing 5 and used in the encoding of computer-generated holograms. 6 In this paper we propose to generate continuous complex reference functions for the JTC that employs a three-component decomposition.…”

Representing Bipolar And Complex Imagery In Noncoherent Optics Image Processing Systems: Comparison Of Approaches

“…21 phase analysis of the video signal. We note that frequency domain processing (either partial coherent optical or temporal frequency filtering of video signal) is used to decode carrier modulated images, whereas decoding multichannel-represented data is done on pointby -point (of the decoded image) base.…”

Acousto-optic processing of two-dimensional signals

“…The specifics of complex signal processing using incoherent light have been extensively reported. [5][6][7] AOl is uniformly illuminated by an incoherent pulsed-light source. This light source can be a light-emitting diode that is pulsed by an electronic signal.…”

“…Alternatively, multiple masks can be used. 7 The light-intensity distribution at plane P3 is given by the product…”
