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 (10μm to 200μm), Pixel Aspect Ratio (0.5 to 1.5), and Frame Aspect Ratio (0.5 to 1.5). This flexibility is desinged to accommodate the specific characteristics of all NASA's satellite imaging sensors of the '70's and '80's. RCA renamed this system "Operational Laser Beam Recorder" (OLBR) to reflect the production evnironment in which this versatile, high performance image recorder must operate. Design techniques and objectives are presented which meet the required flexibilities while maintaining simplicity of design, repeatability, quality of performance, and operabil ity in an image production environment. Human factors, careful partitioning of sub-systems and innovative design techniques are successfully employed to yield a versatile film recording system with a minimum of operational complexity.
