Zusammenfassung:Described herein is a hyperspectral imaging system in which a polarizing beam splitter, a Wollaston prism, an optical system, and a plane mirror are arranged on an optical axis of the imaging system. An imaging detector is provided on which radiation is focused by an imaging lens. The Wollaston prism is imaged on itself by the optical system and the plane mirror so that translation of the Wollaston prism in a direction parallel to a virtual split plane of the prism effectively provides an optical path length difference that is the same for all points in the object field.
