Abstract

A system for producing an image by a sequence of intensity values representing pixels of the image which employs means for scanning the image at a non-linear rate and further, includes means modulating the basic illumination and intensity of pixels as a function of scanning speed. The scanner provides a reciprocating scan and in a specific embodiment, a bi-directional scan whereby pixels are projected during both forward and reverse line sweep. The scan pattern is typically sinusoidal but can be any repeatable scan. The rate of output of video data is proportional to the rate of scan as is the average intensity of the output.
