Development of Optical Sighting System for Moving Target Tracking

Open Access Open Access


In this study, we developed an optical sighting system capable of shooting at a long-distance target by operating a digital gyro mirror composed of a gyro sensor and an FSM. The optical sighting system consists of a reticle part, a digital gyro mirror (FSM), a parallax correction lens, a reticle-ray reflection mirror, and a partial reflection window. In order to obtain the optimal volume and to calculate the leading angle range according to the driving angle of the FSM, a calculation program using Euler rotation angles and a three-dimensional reflection matrix was developed. With this program we have confirmed that the horizontal leading angle of the developed optical sighting system can be implemented under about ±8° for the maximum horizontal driving angle (β = ±12.5°) of the current FSM. Also, if the β horizontal driving angle of the FSM is under about ±15.5°, it can be confirmed that the horizontal direction leading angle can be under ±10.0°. If diagonal leading angles are allowed, we confirmed that we can achieve a diagonal leading angle of ±10.0° with a vertical driving angle α of ±7.1° and horizontal driving angle β of ±12.5°.
