This paper presents the main parameters of a new prism for rotating im
ages in a device that uses a multielement photodetector and rotational
-rotational motion of the scanned field when it is also optically rota
ted. The prism excels known analogs by a factor of 1.5 in the transmis
sion of radiation for an equal mass. (C) 1996 The Optical Society of A
