Document Type and Number:
WIPO Patent Application WO/2024/020178
Kind Code:
A3
Abstract:
A compact structure for snapshot hyperspectral imaging may include an image slicer, an integral field unit, an integral field spectrograph, and multiplexed integral field spectrograph. The image slicer includes a first section having a first plurality of mirrors, each mirror of the first plurality of mirrors having a predetermined tilt in a longitudinal direction, a second section having a second plurality of mirrors, each mirror of the second plurality of mirrors having a predetermined tilt in the longitudinal direction, and a ridge extending laterally between the first section and the second, the first section being at a first angle relative to the ridge and the second section being at a second angle opposite to the first angle relative to the ridge. The integral field unit source includes a four mirror design including an image slicer. The integral field spectrograph includes an array of spectrographs and an image slicer.
