Abstract

Rangefinders operating at a wavelength of 10.6 microns have good performance in conditions of poor visibility, are optically compatible with thermal viewing systems and are eye-safe; these advantages are particularly important for military applications. To demonstrate the feasibility of rangefinding at this wavelength prototype pulsed carbon dioxide (002) laser rangefinders have been developed. The prototype equipment has a mod-ular construction and uses a Marconi Avionics sealed off CO2 transversely excited atmospheric (TEA) laser tube in the transmitter unit. The receiver unit smploys germanium optics and a lead tin telluride (LTT) detector which is cooled to 77 K. Trials of this laser rangefinder have been conducted against a variety of targets and a ranging performance of up to 9 km with an accuracy of + 5 m has been demonstrated.
