Abstract
Heterodyne systems operating in the infrared have been developed for rangefinding, velocity measurement and anemometry. More recently such systems have been extended to cover vibration detection and active imagery (ref. 1). These advanced systems have frequently used a cadmium mercury telluride photodiode operating at 77K as a wide bandwidth, high sensitivity detector of CO2 laser radiation. In practical systems this type of detector may be disadvantageous because of the requirement for high pressure air to achieve the operating temperature.© (1986) COPYRIGHT SPIE--The International Society for Optical Engineering.
