ABSTRACT:
An optical system including a Koster's prism for splitting an optical path into twin paths so that an image propagating along the path from an object plane is incident upon one or the other of two parallel linear arrays of photosensor elements disposed in a common image plane. The arrangement provides a way to optically compact the photosensors in a continuous image line to improve the resolution of the image sensed by the photosensors.
