Paper Abstract

The High Resolution Film Recording System (HRFRS), recently delivered to NASA/Goddard Space Flight Center by RCA, is uniquely characterized by full flexibility in: resolution (1,000 to 20,000 pixels/scan), line rate (15-350' lines/sec), data rate (0.5 to 20 Mbit/sec), optical spot size (10 itaM to 200 pm), pixel aspect ratio (0.5 to 2.0), and frame aspect ratio (0.5 to 2.0). This flexibility is designed to accommodate the specific characteristics of all NASA's satellite, imaging sensors of the 1970s and 1980s. RCA renamed this system Operation Laser Beam Recorder (OLBR) to reflect the production environment in which this versatile, high performance image recorder must operate. Design tech niques and objectives are presented which meet the required flexibilities while maintaining simplicity of design, repeatability, quality of performance, and operability in an image production environment. Human factors, careful partitioning of subsystems, and innovative design techniques are successfully employed to yield a versatile film recording system with a minimum of operational complexity..
