Multiplane Holographic Imaging Using the Spatial Light Modulator

open access: yesPhotonics, 2023
The optimization of imaging accuracy and speed is a crucial issue in the development of computer-generated holograms (CGH) for three-dimensional (3D) displays. This paper proposes an optimized iterative algorithm based on the angular spectrum method (ASM)

Phase-only transmissive spatial light modulator based on tunable dielectric metasurface [PDF]

open access: yesScience, 2019
Dynamic metasurfaces Nanostructured metasurfaces can function as many passive optical elements. Now, S.-Q. Li et al. demonstrate that metasurfaces can be combined with liquid crystals to provide active control over light beams.

High Fidelity Spatial Light Modulator Configuration for Photo-Stimulation

open access: yesFrontiers in Physics, 2021
For their capacity to shape optical wavefronts in real time into any desired illumination pattern, phase-only Spatial Light Modulators (SLM) have proven to be powerful tools for optical trapping and micromanipulation applications.

Holographic Display System to Suppress Speckle Noise Based on Beam Shaping

open access: yesPhotonics, 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]

open access: yesJournal 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 Modulator Microscopy [PDF]

open access: yesCold 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.

Application of a liquid crystal spatial light modulator to laser marking [PDF]

open access: yes, 2011
Laser marking is demonstrated using a nanosecond (ns) pulse duration laser in combination with a liquid crystal spatial light modulator to generate two-dimensional patterns directly onto thin films and bulk metal surfaces.

Controlled Excitation of Supermodes in a Multicore Fiber with a 5 × 5 Square Array of Strongly Coupled Cores

open access: yesPhotonics, 2021
Coherent propagation of supermodes in a multicore fiber is promising for power scaling of fiber laser systems, eliminating the need for the active feedback system to maintain the phases between the channels. We studied the propagation of broadband pulsed

Reconfigurable terahertz metasurfaces coherently controlled by wavelength-scale-structured light

open access: yesNanophotonics, 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 ...
