Analog Spatial Light Modulators Based on Micromirror Arrays [PDF]
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 ...

Single-photon three-qubit quantum logic using spatial light modulators [PDF]
Nature Communications, 2017 Photons are essential for quantum information processing, but to date only two-qubit single-photon operations have been realized. Here the authors demonstrate experimentally a three-qubit single-photon linear deterministic quantum gate by exploiting ...

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

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 ...

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 ...

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.
