Experimental demonstration of holographic three-dimensional light shaping using a Gerchberg–Saxton algorithm
We use a three-dimensional Gerchberg–Saxton algorithm (Shabtay (2003) Opt. Commun. 226 33) to calculate the Fourier-space representation of physically realizable light beams with arbitrarily shaped three-dimensional intensity distributions. From this representation we extract a phase-hologram pattern that allows us to create such light beams experimentally. We show several examples of experimen...
متن کاملGaze Estimation for Near-Eye Display Based on Fusion of Starburst Algorithm and FERN Natural Features
In future, near-eye display devices will be commonly used by people with or without prescription glasses, with different eye topologies, and under different lighting variations. Gaze tracking is an important task for these near-eye devices. New robust gaze tracking methods should be explored for these sophisticated devices. The proposed method overcomes the problem of adaptability to eye topolo...
متن کاملDevelopment of a doubly weighted Gerchberg-Saxton algorithm for use in multibeam imaging applications.
We report on the development of a doubly weighted Gerchberg-Saxton algorithm (DWGS) to enable generation of uniform beamlet arrays with a spatial light modulator (SLM) for use in multiphoton multifocal imaging applications. The algorithm incorporates the WGS algorithm as well as feedback of fluorescence signals from the sample measured with a single-photon avalanche diode (SPAD) detector array....
متن کاملActive Optical Tracking with Spatial Light Modulators THESIS
Two spatial light modulators (SLMs) are utilized for beam splitting, steering and tracking. Both linear and holographic phase screens are used in a demonstration of technology to allow real time tracking to communicate in a one-to-several type scenario. One SLM is used to apply a linear phase modulation to steer multiple beams onto a detector. The spots that are produced represent the targets a...
متن کاملCircular holographic video display system.
A circular holographic video display system reconstructs holographic video. Phase-only spatial light modulators are tiled in a circular configuration in order to increase the field of view. A beam-splitter is used to align the active area of the SLMs side by side without any gap. With the help of this configuration observers can see 3D ghost-like image floating in space and can move and rotate ...
