Close Range Targeting Scope Corrector (CRTSC)

UAH-P-11007-Close Range Targeting Scope Corrector (CRTSC)

Docket: UAH-P-11007


Long range target practice requires a wide spread of areas and distance, due to the conventional reticle scope, which magnifies the target from afar. However, the conventional device could prove a hassle in a limited environment, especially for target practice within a simulation program within a closed room. The reason is that if a target is too close to aim, it alters the relative positions of the reticle and target, resulting in faulty aiming.

Researchers at UAH have invented a close range targeting scope corrector (CRTSC) to be mounted in front of the scope which transforms the nearby scene into one that appears to be far away, allowing the reticle to be aligned with the target.

The CRTSC makes the target appear far enough away for the user to aim with precision without the parallax effects. This enables long range target practice within a limited environment.
