Abstract
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.
Claims10
A targeting sight, comprising:
- a target sight body;
- a light generating source structured to generate a target light and project it toward a target;
- an aperture formed in the target sight body;
- a fiber optic disposed in the aperture;
- a target light sensor disposed in the aperture and structured to sense a brightness of the target through the fiber optic while excluding ambient light from the target light sensing;
- 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.

2 more elements
A method for controlling a target light generator in a targeting sight, the method comprising:
- reading a present brightness of a target and generating a brightness level therefrom;
- storing the brightness level in a memory;
- generating an average brightness value from two or more stored brightness levels;
- comparing the present brightness of the target to the average brightness value;
- and
- generating a target light generator control signal based on the comparison of the present brightness of the target to the average brightness value.
