A 2.06 micron-laser rangefinder technology
Abstract
A laser rangefinder receiver using a photoconductive, thermoelectrically cooled HgCdTe detector was developed for detection of the 2.06 micron wavelength Holmium laser. The HgCdTe receiver was tested with an RCA developed Ho:YLF laser as a laser rangefinder. Quantitative ranging tests were conducted and compared to predicted results utilizing the measured Noise Equivalent Power (NEP) of (5 - 10) (10 to the minus 10th power/square root of (Hz)) of the detector pre-amplifier. A lpps thermoelectrically cooled Ho:YLF laboratory laser was successfully developed and tested to 140 F.
