Abstract

This paper presents a multidirectional beam steering reflector (MBSR) actuated by hydraulic control. It consists of three substrates, an elastic membrane, a magnetic base and a mirror reflector (MR). The MR is fixed on the magnetic base and covered upon the top substrate. The bottom substrate is designed with three channels for pulling in/out the liquid. When liquid volume changes, the shape of the elastic membrane changes to form a liquid piston, accordingly. The liquid piston can make the MR rotate to different directions. When a light beam irradiates the MR, it can achieve the function of beam steering in latitude and longitude, simultaneously. Our experiments show that the proposed MBSR can deflect the light beam through a maximum angle of 0~12.7° in latitude and six-directions in longitude. The MBSR has potential applications in the fields of free-space optical communications, laser detections and solar cells.
