US12516906 - Target dot sight having target illumination sensor

A target dot sight includes a target illumination sensor that senses the amount of illumination at a target, rather than merely sensing the ambient sight of the entire operating environment. Then, based on the sensed target illumination, the target dot sight may automatically compensate for the brightness of the target.

The patent describes a target dot sight equipped with a sensor that measures the brightness of the target, allowing for automatic adjustment of the sight’s illumination based on the detected light levels. This innovation aims to enhance targeting accuracy by ensuring optimal visibility of the target dot in varying lighting conditions.

Claim 1

1 . A target sight, comprising: a target sight body; a light generating source structured to generate a lighted target dot or target pattern; an aperture formed in a front surface of the target sight body, the aperture having an opening at the front surface of the target body and a recessed end; a target light sensor disposed in the recessed end of the aperture and structured to sense a brightness of the target; a sensor lens disposed in the aperture between the target light sensor and the opening of the aperture, the lens structured to focus light from the target on the target light sensor; and a brightness controller structured to control the light generating source based at least in part on the brightness sensed by the target light sensor. a target sight body; a light generating source structured to generate a lighted target dot or target pattern; an aperture formed in a front surface of the target sight body, the aperture having an opening at the front surface of the target body and a recessed end; a target light sensor disposed in the recessed end of the aperture and structured to sense a brightness of the target; a sensor lens disposed in the aperture between the target light sensor and the opening of the aperture, the lens structured to focus light from the target on the target light sensor; and a brightness controller structured to control the light generating source based at least in part on the brightness sensed by the target light sensor.
