The unidentified system in this photograph was part of a study made by Beckman Instruments' Space Engineering Group (SEG) for the United States Air Force in 1964, investigating the feasibility of remote detection of personnel. This study involved a variety of equipment and instruments, including ultraviolet and flame emission spectrophotometers, organic analyzers, and ionization particle counters. Eventually these studies were used by the United States military in the design of counter infiltration systems for warfare.
