ABSTRACT:
An optical deflector is disclosed in which a polygonal prism is rotatively driven by a polygonal prism driving circuit and an emergent light beam from the polygonal prism effects repeated scanning with the rotation of the polygonal prism. Also disclosed is a display unit in which an image for one horizontal cycle displayed on a one-horizontal-scanning-line display device is vertically scanned by an optical deflector using a polygonal prism or a rotating mirror so as to be sent to a visual point via an eyepiece.
