3D Computational Ghost Imaging [PDF]
The Rochester Conferences on Coherence and Quantum Optics and the Quantum Information and Measurement meeting, 2013 Computational ghost imaging retrieves the spatial information of a scene using a single pixel detector. By projecting a series of known random patterns and measuring the back reflected intensity for each one, it is possible to reconstruct a 2D image of ...

Applied Optics, 2023 We present current results of a novel type of setup for quantum ghost imaging based on asynchronous single-photon timing using SPAD detectors, first presented in [1]. The scheme enables photon pairing without fixed delays and thus overcomes some limitations of the widely used heralded setups for quantum ghost imaging [2].

Performance evaluation of dual-layer architectures for high dynamic range head mounted displays
Journal of Information Display, 2023 A high dynamic range head mounted display (HDR-HMD) using a dual-layer per-pixel modulation method was recently demonstrated where both the display and modulation layers spatially overlap with an equal pixel resolution and are well-aligned to each other ...
