High-throughput hyperspectral microscopy

A hyperspectral imager provides a 3-D data cube in which the spatial information (2-D) of the image is com-plemented by spectral information (1-D) about each spatial location. A static, high-throughput spectrometer design previously developed by our group can be used as the spectral engine in a high-throughput hyperspectral imager that avoids the Fourier undersampling issues present in previous dispersive designs. We present the the-ory for both pushbroom and tomographic operation and describe experimental results from our proof-of-concept implementation of a hyperspectral microscope
