Before proceeding to a discussion of particular SLMs, it is worth summarizing their salient parameters (Table 8.1), which were discussed in Sect.2.3. Note that in some specific applications the requirements on SLM parameters may lie beyond the ranges indicated here, because we give values for the sake of reference.

Spatial modulation display using spatial light modulators
Optical Engineering, 1992A spatial modulation display is described that permits the observation of a phantom or transparent image by several persons simultaneously and is suitable for medical imaging. The display uses spatial light modulators and large format convex lenses within a Schlieren optical system. The number of sectional images in a three-dimensional image is limited

Scophony Spatial Light Modulator
Optical Engineering, 1985An alternative to the conventional flying-spot scanner architecture is the Scophony scanner. The Scophony scanner uses the same optical elements as the more familiar flying-spot scanner: a rotating polygon mirror, an acousto-optic (A/O) modulator, and a laser light source. The flying-spot scanner is designed to construct its image a pixel at a time; no

Analog spatial light modulator
Soviet Journal of Quantum Electronics, 1983An analysis is made of the construction, operating principle, and possible applications of analog spatial light modulators performing the function of a rotating slit and intended for optical data processing systems. A report is given of the characteristics of prototype modulators in which liquid crystals are used and a theoretical analysis of their ...

Photovoltaic spatial light modulator
Journal of Applied Physics, 1991A novel concept for implementing a high-resolution spatial light modulator using a thin slab of photorefractive LiNbO3 crystal is described. This method uses the photovoltaic effect to impress phase information onto the crystal without the use of holography where coherent reference beams are required.

In chapter 4 the so-called classical optical elements were introduced in some detail. Advanced scientific and technological optical systems require more sophisticated elements, in particular interface devices that provide a conversion between electronic and optical signals.

Publisher Summary This chapter discusses spatial light modulator, which comprises a photocathode, micro channel plate, mesh electrode, and a LiNbO3 crystal in a vacuum-sealed tube. The device is a transducer for incoherent to coherent light conversion; it is highly sensitive and can be used over a wide wavelength range. It can also be used to perform

Winner-take-all spatial light modulator
Optics Letters, 1992An optical winner-take-all spatial light modulator has been implemented with very-large-scale integrated circuit/liquid-crystal device technology. One-dimensional arrays varying in size from 2 to 64 units and a 32 x 32 unit two-dimensional array have been fabricated and have demonstrated winner-take-all behavior.

Spatial light modulator for texture classification
Applied Optics, 1989This paper describes a hybrid computer-optical processor devoted to the analysis of texture. Textures are displayed on a spatial light modulator and their power spectra are calculated optically by a Fourier optical technique. A video camera and a computer with a frame digitizer process the power spectra.
