DOI: 10.1016/j.optcom.2020.126527

Abstract: Abstract Single-pixel imaging (SPI) is a novel optical imaging technique capable of handling unusual imaging conditions such as invisible wavebands and indirect line of sight. In SPI, the target object is sequentially illuminated with various… read more here.

DOI: 10.1016/j.optlaseng.2019.105955

Abstract: Abstract We present two novel techniques in single-pixel imaging (SPI): the first one is Hadamard-Bayer SPI in which the Hadamard-Bayer illumination patterns are employed for fast full-color SPI, with a sampling rate and computational complexity… read more here.

DOI: 10.1364/oe.27.019788

Abstract: In nonlinear microscopy, phase-only spatial light modulators (SLMs) allow achieving simultaneous two-photon excitation and fluorescence emission from specific region-of-interests (ROIs). However, as iterative Fourier transform algorithms (IFTAs) can only approximate the illumination of selected ROIs,… read more here.

DOI: 10.1364/ol.563798

Abstract: Optical imaging with single-pixel detection could not work well in some complex scenarios, when a single type of illumination patterns is applied. Here, we report on correspondence imaging (CI) with mixed illumination patterns to achieve… read more here.
