High-dynamic-range fluorescence laminar optical tomography (HDR-FLOT)

Biomedical Optics Express, 2017
Three-dimensional fluorescence laminar optical tomography (FLOT) can achieve resolutions of 100-200 µm and penetration depths of 2-3 mm. FLOT has been used in tissue engineering, neuroscience, as well as oncology. The limited dynamic range of the charge-coupled device-based system makes it difficult to image fluorescent samples with a large ...

Reduced-Dimensional Capture of High-Dynamic Range Images with Compressive Sensing

Discrete Dynamics in Nature and Society, 2020
The range of light illumination in real scenes is very large, and ordinary cameras can only record a small part of this range, which is far lower than the range of human eyes’ perception of light.
