Abstract
Apparatus is described for scanning a scene in bands of lines and reconstructing the scene in visible light. Use is made of a prism having mirrors which subtend a sequence of various tilt angles with an axis of rotation. According to the invention, all but one of the mirrors are used for scanning and reconstruction. To achieve this, the angular spacing between the scanning and reconstruction locations around the prism is an integral multiple of the angular spacing between adjacent mirrors, which multiple is not a sub-multiple of the total number of mirrors. For all but one of the mirrors, the tilt angle of a mirror at a scanning location differs from the tilt angle of the mirror simultaneously present at a reconstruction location by the same amount and in the same direction.
