Abstract:
1. A telescopic sight for firearms comprising: a set of lenses disposed along a linear optical path including an objective lens, an erector lens assembly and ocular lens; a rangefinding system including a rangefinding light transmitter adapted to transmit a beam through the objective along the linear optical path and a rangefinding light receiver adapted to detect rangefinding light reflected back to the telescopic sight along the linear optical path through the objective lens, wherein the rangefinding light receiver generates a range signal indicative of a range of an object reflecting the rangefinding light; a lookup table stored in a memory containing ballistics information; a processor that, based on the range signal and the ballistics information, determines an aiming point relative to the linear optical path; a plurality of LEDs on a transmissive plano located on the linear optical path and the LEDs oriented to emit light substantially only along the optical path toward the ocular lens; and the processor further adapted to selectively illuminate one or more LEDs to form a light-emitting reticle viewable by a user through the ocular lens so that the light-emitting reticle is co-located with the determined aiming point.
