We report a new type of high-speed electro-optic (E-O) beam scanner based on Potassium Tantalate Niobate (KTN) crystal. It has larger scanning angle, better angular resolution, and lower driving voltage comparing to the traditional E-O crystal beam scanner. Compared to conventional moving mirrors such as servo-controlled mirrors and galvanic mirrors, the demonstrated E-O beam scanner can improve the response time by 100 times. The presented device has many other unique features such as light weight, small dimension, low power consumption, and no-moving components particularly suitable for airborne and space-borne applications.
