Holographic Display System to Suppress Speckle Noise Based on Beam Shaping
Photonics, 2021 In this paper, a holographic system to suppress the speckle noise is proposed. Two spatial light modulators (SLMs) are used in the system, one of which is used for beam shaping, and the other is used for reproducing the image.

Wide-field common-path incoherent correlation microscopy with a perfect overlapping of interfering beams [PDF]
Journal of the European Optical Society-Rapid Publications, 2013 Incoherent correlation microscopy is recently discovered technique for digital imaging of three-dimensional objects in a quasi-monochromatic spatially incoherent light. Its operation is based on wavefront division carried out by a spatial light modulator

Microchannel spatial light modulator [PDF]
Optics Letters, 1978 A sensitive, high-speed, optically addressed spatial light modulator is being developed for real-time optical dataprocessing applications involving low-level-control light signals. This device is expected to have a sensitivity of better than 10(-3) microJ/cm(2), a framing rate of about 1 kHz, and a spatial resolution of approximately 20 line pairs/mm ...

Spatial Light Modulator Microscopy [PDF]
Cold Spring Harbor Protocols, 2013 The use of spatial light modulators (SLMs) for two-photon laser microscopy is described. SLM phase modulation can be used to generate nearly any spatiotemporal pattern of light, enabling simultaneous illumination of any number of selected regions of interest.

Reconfigurable terahertz metasurfaces coherently controlled by wavelength-scale-structured light
Nanophotonics, 2021 Structuring light–matter interaction at a deeply subwavelength scale is fundamental to optical metamaterials and metasurfaces. Conventionally, the operation of a metasurface is determined by the collective electric polarization response of its ...
