When a pixellated spatial light modulator (SLM) is used in an optical processor, replicated images occur in the output due to the underlying regular pixel structure of the SLM. These replicas arise through convolution with distinct spectral orders in

The construction of a 50- x 50-pixel spatial light modulator based on an active silicon backplane and using the hybrid field effect in nematic liquid crystals as the light modulating process is described. The design and electrical evaluation of the p

Replication in the output plane of an optical correlator, due to pixelation of the Fourier plane filter, can lead to false correlation signals. This paper suggests randomization of the pixel positions of the Fourier plane filter as a solution, and de

The development of a ferroelectric liquid-crystal-over-single-crystal-silicon spatial light modulator is described. The reflective SLM has an array of 176 X 176 pixels over a clear aperture of 5.28 mm X 5.28 mm. Prototype devices driven from a specia

The construction and principle of operation of a liquid-crystal-over an MOS- array spatial light modulator (SLM) is described. Photographs are presented of patterns produced by amplitude-only modulation of monochromatic light by the SLM when used in

A photon-coincidence counting technique has been used to observe the second-order coherence in a plane receiving light from two small incoherently illuminated apertures. Measurements made for two wavelengths, 546·1 and 435·8 nm, gave results consis

The amplitude distribution in the scalar far-field approximation is derived as a simple expression, involving only sinc functions, in terms of two non-orthogonal coordinates related to the lengths and directions of two sides of the triangle. Photogra

The moment theorem is used to show that the innermost part of the Fraunhofer diffraction pattern of any real aperture with higher than two-fold rotational symmetry is rotationally invariant. Then a formalism is presented in which aperture transmissio
