Abstract
A multi-spectral imaging (MSI) device can include an imaging plane and a diffractive optic. The imaging plane can include at least two groups of pixels an array of pixels for sensing at least two spectral bands. The at least two spectral bands can include a first spectral band and a second spectral band. The diffractive optic can be configured for diffracting an electromagnetic wave into the at least two spectral bands and focusing each spectral band component of the electromagnetic wave onto the group of pixels for the spectral band to generate an image.
