Multispectral Quantitative Phase Imaging Captures Live Human Cells Quickly

摘要

Silicon image sensors collect light across a broader spectral range than simply the visible spectrum. The typical sensitivity range is from 350 nm (UV) to 1100 nm (NIR). A monochrome sensor will form an image from the total integrated intensity across all wavelengths. Combined with a NIR filter, common RGB color cameras employ a pixel-scale dye filtration to restrict the light collected by the camera to three wide bands in the visible.
