Abstract

A system has been designed and built for transmitting images of diffusely reflecting objects through optical fibers and displaying those images at a receiving station. Wavelength coding is used to reduce the number of fibers required for transmission while allowing transmission of >1000 pixels/fiber. The system is an optical/electronic hybrid which operates under computer control. A tunable dye laser is used for a high-brightness light source, and a CRT is used for the output image display. The system and its operation are described, and examples of results are shown.
