Reflective-Mirror-Based Optical Tracking Actuated by Electrowetting Effect
We develop a reflective-mirror-based optical tracking device actuated by the electrowetting effect. It comprises a transparent rectangular cavity, rubber ring, and mirror. When a voltage is applied to the conductive liquid on both sides of the cavity, the conductive liquid on both sides’ surges in the middle. Consequently, the height of the intermediate liquid varies and the mirror forms a tilt angle, thereby changing the deflection direction of the incident light beam, and thus realizing optical tracking. Experimental results that the beam navigation angle can reach 0°-9° with a fast response time (approximately 90 ms). The proposed device has potential applications in space optical communication and radar detection.
