Abstract
A laser rangefinder apparatus is provided which includes a laser transmitter for transmitting a coherent light pulse over an optical path to a target. The light pulse is reflected from the target as a reflected pulse and travels back to the laser rangefinder over the same optical path. The reflected light pulse is provided to a fiber optic interface module which supplies the pulse to a fiber optic interface cable. The fiber optic interface cable supplies the reflected pulse to a laser receiver. The laser receiver includes a signal processor which performs the distance to target calculation and displays the resultant distance to the user. The fiber optic interface module and fiber optic interface cable permit great flexibility in the placement of the laser receiver with respect to the laser transmitter of the rangefinder.
