Abstract

A 1024 x 1024 pixel image digitizer has been developed that provides high speed electro-optical scanning of image transparencies. The system consists of a linear diode array mounted on a stepping motor assembly to produce a 1024 x 1024 pixel array. An optical system projects image transparencies onto the detector at variable scales. One design utilizes a 5:1 zoom lens with 1.0x and 2.4x channels for selection of image sample spacing from 1.3 to 16µm. Another optical design utilizes projection optics to enable sample spacing above 16µm.
