CONTINUOUS FACSIMILE SCANNER EMPLOYING FIBER OPTICS.

Abstract

Photometric imperfections occurring in copy exposed through a fiber sheet were reduced by use of bulk glass rods whose surface had been ground and polished to an optical finish. Evaluation of the linearity, temperature characteristics, and sensitivity of a number of light detectors resulted in selection of a type considered best choice for use in the facsimile scanner. Prototype of scanner assembled and functioned satisfactorily except for minor variations in speed of the copy feed belt. (Author)
