High-Precision Calibration of Phase-Only Spatial Light Modulators
IEEE Photonics Journal, 2022 In the fields of optics and photonics, phase-only spatial light modulators (SLMs) play an increasingly important role in wave-front engineering. However, the SLMs are subject to wavefront distortion arising from the imperfection in the birefringence ...

Analog Spatial Light Modulators Based on Micromirror Arrays
Micromachines, 2021 The Fraunhofer Institute for Photonic Microsystems (IPMS) has been developing and manufacturing micromirror arrays for more than 20 years. While originally focusing on applications related to microlithography and therefore mainly for light in the deep ...

Multicolor Holographic Display of 3D Scenes Using Referenceless Phase Holography (RELPH)
Photonics, 2021 In this paper, we present a multicolor display via referenceless phase holography (RELPH). RELPH permits the display of full optical wave fields (amplitude and phase) using two liquid crystal phase-only spatial light modulators in a Michelson ...

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.

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 ...

Dynamics of Fractional Vortex Beams at Fraunhofer Diffraction Zone
Photonics, 2022 Fractional vortex beams (FVBs) possess unique topological properties that are manifested in the vortex distribution. However, there are still discrepancies in the value of the vortex strength of FVBs at the far field.

Singular Warped Beams Controlled by Tangent Phase Modulation
Photonics, 2021 We analyze the effect of spatial phase modulation using non-linear functions applied to singular warped beams to control their topological states and intensity distribution.

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.

Concentric Perfect Optical Vortex Beam Generated by a Digital Micromirrors Device
IEEE Photonics Journal, 2017 We propose a kind of perfect optical vortex beam (POV) generated via Fourier transformation of Bessel-Gauss (BG) beams through encoding of the amplitude of the optical field with binary amplitude digital micromirrors device.
