STUDY OF FACSIMILE SCANNING AND RECORDING TECHNIQUES EMPLOYING FIBER OPTICS.
Abstract
Modification of the facsimile transmitter T-609 (XC-2)/GX from a conventional scan system to one employing fiber optics is completed. Copy pro duced by this instrument has a resolution in excess of 96 lines per in. An elemental scanner consisting of two illumination fibers and one pick-up fiber did not exhibit the theoretically expected decrease in resolution with an increase in the separation between the probe end and the copy. The lower than expected resolution may be due to an integration of the flux by multiple reflections between the probe and copy. The bulk transmission of a number of fiber bundles is presented. The absorption coefficients indicate a flux loss of approximately 0.5% per in. The design and theory of a photographic recording goniophotometer for determination of fiber numerical aperture is described. (Author)
