Opto-electronic scanning system for image processing - has image scanned by line of LCD devices coupled to photoconverter

摘要

The scanning unit is in the form of a line of LCD elements. Image points provide signals that are focussed by a condenser lens (KL) onto a photo converter stage (PW). The light beam can be provided by a reflector that directs the light onto the surface, with the signals transmitted through the LCD elements. After reception the signals are processed. ADVANTAGE - High resolution and high speed.
