ABSTRACT:
A laser range finder includes a circular in-sight field of view which incorporates within it a magnified "TV view" of the target area with the TV view roughly approximating the rectangular shape of a standard television picture. Also within the circular field, over and under the TV view, are a target quality indicator, a range distance display, and other indicators. Within the TV view is a targeting reticle which indicates roughly the footprint of ranging laser pulses such that a target can be selected. The target quality indicator is a bar graph which displays the number of identifiable received reflected laser pulses from a series of such pulses emitted by the range finder. By aiming the range finder at various targets via the footprint reticle, repeatedly firing the range finder and monitoring the target quality graph for each firing, a user can move the range finder to find a surface proximate the target with a reflective quality sufficient to yield an accurate target range reading. Alternatively, with a range finder equipped with Scan mode capability, the range finder can be slowly panned across multiple targets with the range to each target being displayed, in sequence, on the range display.
