摘要

For LADAR systems with an arbitrary or undetermined scanner system, the raw video data produced is not usually in a form that can be used by standard video display devices such as a television monitor or frame grabber. This raw data must first be processed and organized into a standard video format or into a custom digital format for further processing. If this system is designed as an FPGA-based system, it can be combined with an FPGA-based scanner controller for an even more compact unit. This FPGA-based system can be extremely complex or simple depending on the desired input/output format. Even better, the system can be made reconfigurable to allow many input and output data formats. Such a system has already been designed and is being tested. Many programmable constants are provided to allow modification of the raw data type and output video format. The system can currently accept raw data from the photo-detector at a 4.195KHz horizontal line scan rate and produce a composite RS-170 compliant video signal with a 15.75KHz horizontal line scan rate. The program can adapt to any set of input and output frequencies, sync pulse width, white and black level.
