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

Spatial light modulators [PDF]
Photoniques, 2020 Spatial Light Modulators (SLMs) are quasiplanar devices, allowing for the modulation of the amplitude, phase and polarization, or a combination of these parameters of an incident light beam according to the two spatial dimensions of the modulator. SLMs are employed in many different fields and are the subject of continuous technological development.

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 ...
