Abstract

We have designed a hand-held imaging device which is capable of capturing images of multiple spectral bands, spanning the visible to the near-infrared (NIR), as well as imaging multiple perspective views of an object simultaneously on one detector. This concept utilizes a set of mirrors positioned obliquely to the principle axis of the imaging device that present different perspective views, of a target, and simultaneously bandpass filters those views before the light enters the device. In its current state, our instrument is capable of simultaneously imaging nine independent spectral bands and three different perspective views. The device allows for measurement of multispectral properties of different material enabling multispectroscopic science as demonstrated by studying the separability of four types of black ink. Exploiting the stereoscopic imaging capability of the device, we are able to construct three-dimensional surface features of a target.
