Paper Abstract

Designed and developed as a commercial product designated the KEI Model LH-83, the hand-held eyesafe laser rangefinder was refined and "hardened" for the full military field environment under a competitive Army advanced development contract for the MELIOS (Mini-Eyesafe-Laser-Infrared-Observation-Set) program which is also designated the AN/PVS-6 ( ). The Model LH-83 currently has a weight of 2 kg and is about the size of a pair of binoculars. The monocular device displays system status and range data in the eyepiece. Operation is powered by self-contained AA-sized alkaline, rechargeable NiCd, or long-life Lithium batteries. A major feature of the KEI Model LH-83 and MELIOS design is compartmentalization into three field-replaceable modules (i.e., power supply, range/control and transceiver). From built-in tests, a possible field malfunction can be diagnosed and, by module replacement, the system can be returned to operational status in a matter of minutes. The overall system design is discussed. Subsystem design and performance is detailed in a manner that will enable possible fire control system users to incorporate the modules into various system configurations where an eyesafe laser rangefinder would be advantageous. The Army is in the process of conducting extensive evaluations, which include environmental and field testing. It is expected that these evaluations will be completed by the First Quarter of FY 1986.
