Multi frame holograms batched optimization for binary phase spatial light modulators [PDF]

open access: yesScientific Reports
Phase retrieval methods used in computer generated holograms such as Gerchberg-Saxton and gradient descent give results which are prone to noise and other defects.

Two-photon microscopy with diffractive optical elements and spatial light modulators [PDF]

open access: yesFrontiers in Neuroscience, 2010
Two-photon microscopy is often performed at slow frame rates, due to the need to serially scan all points in a field of view with a single laser beam. To overcome this problem, we have developed two optical methods that split and multiplex a laser beam ...

Model-based compensation of pixel crosstalk in liquid crystal spatial light modulators.

open access: yesOptics Express, 2019
Spatial light modulators (SLMs) based on liquid crystals are widely used for wavefront shaping. Their large number of pixels allows one to create complex wavefronts.

Universal phase-only spatial light modulators

open access: yesOptics Express, 2017
Universal phase-only spatial light modulators (UP-SLMs) are proposed and demonstrated by simulation and experiment. UP-SLMs, which consist of unitarily coupled electrically controllable wave plates, convert the optically anisotropic properties of the paired two wave plates into an effective single isotropic phase plate and can be realized with ...

Generation of arbitrary vector beams with cascaded liquid crystal spatial light modulators.

open access: yesOptics Express, 2014
A flexible approach is presented to generate vector beams with arbitrary polarization and complex amplitude by means of two cascaded transmissive liquid crystal spatial light modulators (LCSLMs).

A multiple-input-multiple-output visible light communication system based on VCSELs and spatial light modulators.

open access: yesOptics Express, 2014
A multiple-input-multiple-output (MIMO) visible light communication (VLC) system employing vertical cavity surface emitting laser (VCSEL) and spatial light modulators (SLMs) with 16-quadrature amplitude modulation (QAM)-orthogonal frequency-division ...

High-Precision Calibration of Phase-Only Spatial Light Modulators

open access: yesIEEE 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 ...

Multicolor Holographic Display of 3D Scenes Using Referenceless Phase Holography (RELPH)

open access: yesPhotonics, 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 ...

Microchannel spatial light modulator [PDF]

open access: yesOptics 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 ...
