Abstract

High performance laser recorder systems require the use of many subsystems to perform auxiliary functions that preserve and enhance image quality. For example, image quality is preserved by subsystems that minimize pixel jitter and facet signature. Additionally, recorder operability and flexibility is greatly increased through the use of microprocessor controlled status and control buses. Microprocessor control architecture allows existing modes to be modified or new modes to be added to the recorder by altering the firmware. A menu driven control panel provides a user friendly interface by limiting the number of decisions required by the operator yet still provides control flexibility. Verification of performance or troubleshooting activity is aided by the versatility of microprocessor controlled test pattern generation. Annotation information generated by the recorder is recorded onto the film and provides valuable archival documentation. Where near real time imagery is required, a wet or dry in-line film processing subsystem, can be incorporated into the recorder design. Using these concepts a recorder system has been built that can record in excess of 10,000 pixels per line onto five inch wide film, at a line rate of 6000 lines per second. Another recorder system has 15 modes to support 4 different sensors and a film speed range of 40:1. Both recorders utilize in-line wet film processors that provide film ready for viewing in near real time. This paper will describe some of these auxiliary subsystems and show how these subsystems impact the overall performance and utility of a recorder.
