SNR study on Fourier single-pixel imaging
New Journal of Physics, 2021 According to the properties of Fourier transform, Fourier single-pixel imaging uses the illumination lights with cosine distributions to obtain the Fourier spectrum of the object, and then apply the inverse Fourier transform to reconstruct the spatial ...

HDR Imaging with Spatially Varying Signal-to-Noise Ratios
2023 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR), 2023 While today's high dynamic range (HDR) image fusion algorithms are capable of blending multiple exposures, the acquisition is often controlled so that the dynamic range within one exposure is narrow. For HDR imaging in photon-limited situations, the dynamic range can be enormous and the noise within one exposure is spatially varying.

Consideration of signal to noise ratio for an imaging bolometer for ITER
Review of Scientific Instruments, 2021 An infrared imaging video bolometer (IRVB) is proposed for ITER having a tangential view of the entire ITER cross section. For the initial estimate of the signal level, a 840 m3 plasma is assumed to uniformly radiate 67.3 MW. A more detailed estimate of the signal strength is provided by synthetic images based on radiation data from SOLPS and SANCO ...
