Unified probability explanation for ghost imaging with thermal light
Wen-Kai Yu, Jian Leng
Ghost imaging (GI) is an intriguing imaging technology which achieves the object images through intensity correlation between reference patterns and bucket signal. Here, we propose…
Phase retrieval without prior knowledge via single-shot Fraunhofer diffraction pattern of complex object
An-Dong Xiong, Xiao-Peng Jin, Wen-Kai Yu +1
Fraunhofer diffraction is a well-known phenomenon achieved with most wavelength even without lens. A single-shot intensity measurement of diffraction is generally considered inadeq…
Formation mechanism of correspondence imaging with thermal light
Jian Leng, Wen-Kai Yu, Shuo-Fei Wang
Correspondence imaging can achieve positive-negative ghost images by just conditional averaging of partial patterns, without treating bucket intensities as weights. To explain its…
Domino successive-deviation ghost imaging
Ya-Xin Li, Wen-Kai Yu, Shuo-Fei Wang
Traditional ghost imaging acquires images via the correlation of the intensity fluctuations of reference patterns and bucket values, and can even generate positive-negative images…
Three-dimensional imaging with single-frame jigsaw-puzzle-reorganized sinusoidal fringe using multi-pixel axial flat brush scanning
Wen-Kai Yu
Structured-light three-dimensional (3D) imaging can achieve 3D shape of a stationary object via one or more pixelated array cameras with phase-shifting illumination. In order to ex…
Cryptographic key distribution over a public network via variance-based watermarking in compressive measurements
Wen-Kai Yu
The optical communication has an increasing need for security in public transmission scenarios. Here we present a protocol for cryptographic key distribution over a public network…
Single-pixel imaging with origami pattern construction
Wen-Kai Yu, Yi-Ming Liu
Single-pixel compressive imaging can recover images from a small amount of measurements, offering many benefits especially for the scenes where the array detection is unavailable.…
Super sub-Nyquist single-pixel imaging by means of cake-cutting Hadamard basis sort
Wen-Kai Yu
Single-pixel imaging via compressed sensing can reconstruct high-quality images from a few linear random measurements of an object/scene known a priori to be sparse or compressive,…
