Auto Aim Reticle For Laser range Finder Scope

摘要

A laser range finder scope for measuring the distance between a target and the scope based on the time-of-flight of laser impulses is disclosed as including means for transmitting laser impulses toward the target and generating a first time signal corresponding to the transmission; means for receiving laser impulses reflected from the target and generating a second time signal corresponding to the reception; means for delaying said first time signal to provide a third time signal; means for calculating the time-of-flight by comparing said second time signal and third time signal; and a scope with a reticle with a plurality of indicia selectively lightable to each indicate the appropriate reticle scale to aim at the target.
