abstract

Advances in laser devices, control electronics, and data processing software have enabled significant improvements in tunable diode laser sensor design in the last several years. Miniaturization of the primary subsystems and development of robust data analysis software for space applications has enabled diode laser sensors to be considered for applications where they previously were not feasible due to size, weight, power constraints, or cost. The substantial reductions in diode laser sensor footprint and power consumption achieved at the Jet Propulsion Laboratory between 1992 and 1996 have led to the development of hand- held, battery-operated sensors for the Space Station, the fist space-qualified diode laser sensors presently en route to Mars, and a small humidity sensor suitable for use on commercial aircraft. An overview of the current status of sensor development at SpectraSensors and JPL is presented in this paper.
