GE ARRAY OF COUNTERS NORMALLY ASSOCIATED WITH SUCH A SYSTEM AND A MINICOMPUTER TO HANDLE DATA MANIPULATION AND DISPLAY. The speed and versatility make the system a reasonable alternative to systems presently in use. System features include a 250 MHz photon counting rate, 100 nanosecond minimum sample interval, up to 512 channel data accumulation with sub-nanosecond switching times between channels, and a maximum laser transmitter repetition rate of 10 KHz. This system offers several advantages over presently available systems, such as allowing the higher laser repetition rates needed to monitor a rapidly fluctuating atmosphere without sacrificing spatial resolution or the total number of data channels, and enabling real-time modification of the system operating parameters as a function of incoming data. This paper describes the parameters influencing the design of such a system. Author
