Computational multispectral video imaging [Invited]

Journal of the Optical Society of America A, 2017
Multispectral imagers reveal information unperceivable to humans and conventional cameras. Here, we demonstrate a compact single-shot multispectral video-imaging camera by placing a micro-structured diffractive filter in close proximity to the image sensor.
