Snapshot hyperspectral imaging

Example of a snapshot hyperspectral imaging spectrometer.
Example of a snapshot hyperspectral imaging spectrometer. The scene is viewed through a lenslet array. Each lenslet transmits the light it receives to the fiber to which it is coupled. The bundle of fibers is reformatted and lined up at the entrance slit of a conventional grating spectrometer, which disperses the light across the entrance slit onto its detector.

Snapshot hyperspectral imaging[1] is a method for capturing hyperspectral images during a single integration time of a detector array. No scanning is involved with this method, in contrast to push broom and whisk broom scanning techniques. The lack of moving parts means that [2] motion artifacts should be avoided. This instrument typically features detector arrays with a high number of pixels.
