Abstract

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 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.
