Abstract

This paper discusses a high-resolution laser image transmission system recently designed, built, and tested under contract to Rome Air Development Center. The system and equipment was designed for two-way transmission of intelligence and reconnaissance imagery over narrowband communication links. The following technological advances embodied in the system are covered in this paper. The use of source encoding on the image data to achieve an average of 15:1 reduction in the transmitted data •Economical achievement of high-resolution imagery with 20-Ip/mm scanning resolution •Synchronizing encoding for transmission over 9.6-kb/s wire-line links in a heavily errored environment •Use of a modulated laser as a scanning and reproducing light source •Use of dry-silver photocopy as the output media
