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 ...

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 ...

Encoding the Intensity and Phase Gradient of Light Beams with Arbitrary Shapes
Applied Sciences, 2023 We present an approach for engineering the intensity trajectory and phase gradient of light beams with arbitrary shapes by estimating their parametric equations using Freeman chain code and by applying the fast Fourier transform.

Endoscopic Imaging Using a Multimode Optical Fibre Calibrated with Multiple Internal References
Photonics, 2022 The interferometric acquisition of the transmission matrix (TM) of a multimode optical fibre (MMF), which is at the heart of multimode fibre-based endoscopic imaging methods, requires using a reference beam. Attempts to use an internal reference, that is

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 ...

Holographic Display System Based on Effective Area Expansion of SLM
IEEE Photonics Journal, 2019 In this paper, a holographic display system with wide viewing area is proposed based on the effective area expansion of the SLM. The effective area of the SLM is calculated based on the viewing area characteristics and expanded by using two SLMs ...
