Abstract : Research was continued on a study of theoretical and experimental problems related to the utiliza tion of dielectric fibers in a facsimile scanner and recorder. An elemental scanner was constructed to study scanning parameters and resolution of fiber optics illuminating and scanning systems. For the purpose, an automatic microdensitometer, designed to measure and record transmission density of film, was modified to measure reflection density of opaque copy. A recording spectrophotometer was modified to measure spectral transmission of fiber bundles in a study of transmission characteristics of individual fibers. A study of strength coefficients of coated fibers was initiated in connection with a search for glass combinations with optimum strength consistent with acceptable optical properties. Facsimile set NA/GXC-4(XC-2) was delivered and work is in progress for its modification to accommodate fiber optics components. (Author)
