TL;DR: The number of deflected mirror elements as well as the degree of deflection determines the amount of reflected radiation which travels through an aperture and is collimated by suitable imaging optics, thus creating an infrared image that appears to be at infinity as mentioned in this paper.
Abstract: The mirror elements mirror device spatial light modulator are selectively deflected. Such deflection causes incident infrared radiation to be reflected in selected directions. The number of deflected mirror elements as well as the degree of deflection determines the amount of reflected radiation which travels through an aperture and is collimated by suitable imaging optics, thus creating an infrared image that appears to be at infinity.

TL;DR: An integral constraint is developed that is a necessary condition for optimizing a correlation filter having single parameter coupling between phase and amplitude and the phase-only filter is shown to be a special case.
Abstract: In correlation filtering a spatial light modulator is traditionally modeled as affecting only the phase or only the amplitude of light. Usually, however, a single operating parameter affects both phase and amplitude. An integral constraint is developed that is a necessary condition for optimizing a correlation filter having single parameter coupling between phase and amplitude. The phase-only filter is shown to be a special case.

TL;DR: In this paper, the authors proposed a direct write system for polymer array synthesis, where each pixel is illuminated with an optical beam of suitable intensity and the imaging (printing) of an individual feature is determined by computer control of the spatial light modulator at each photolithographic step.
Abstract: An improved optical photolithography system and method provides predetermined light patterns generated by a direct write system without the use of photomasks. The Direct Write System provides predetermined light patterns projected on the surface of a substrate (e.g., a wafer) by using a computer controlled means for dynamically generating the predetermined light pattern, e.g., a spatial light modulator. Image patterns are stored in a computer and through electronic control of the spatial light modulator directly illuminate the wafer to define a portion of the polymer array, rather than being defined by a pattern on a photomask. Thus, in the Direct Write System each pixel is illuminated with an optical beam of suitable intensity and the imaging (printing) of an individual feature is determined by computer control of the spatial light modulator at each photolithographic step without the use of a photomask. The Direct Write System including a spatial light modulator is particularly useful in the synthesis of DNA arrays and provides an efficient means for polymer array synthesis by using spatial light modulators to generate a predetermined light pattern that defines the image patterns of a polymer array to be deprotected.

TL;DR: An optical system for synthesizing double-phase complex computer-generated holograms using a phase-only spatial light modulator and a phase grating filter to synthesize arbitrary complex optical field distributions is proposed.
Abstract: We propose an optical system for synthesizing double-phase complex computer-generated holograms using a phase-only spatial light modulator and a phase grating filter. Two separated areas of the phase-only spatial light modulator are optically superposed by 4-f configuration with an optimally designed grating filter to synthesize arbitrary complex optical field distributions. The tolerances related to misalignment factors are analyzed, and the optimal synthesis method of double-phase computer-generated holograms is described.

TL;DR: A programmable, high-rate scanning femtosecond pulse shaper based on a two-dimensional liquid crystal on a silicon spatial light modulator (SLM) and an update rate in excess of 100 kHz is demonstrated.
Abstract: We introduce a programmable, high-rate scanning femtosecond pulse shaper based on a two-dimensional liquid crystal on a silicon spatial light modulator (SLM). While horizontal resolution of 1920 addressable pixels provides superior fidelity for generating complex waveforms, scanning across the vertical dimension (1080 pixels) has been used to facilitate at least 3 orders of magnitude speed increase as compared with typical liquid-crystal SLM-based pulse shapers. An update rate in excess of 100 kHz is demonstrated.
