Abstract
A LIDAR system includes a laser source configured to emit an optical beam; a detector module configured to receive and analyze the reflected optical signals; a scanning module having one or more scanning elements configured to control the direction of the optical beam with an acousto-optic deflector (AOD), wherein the AOD includes: an optical element having a surface with one or more steps formed thereon; a conductive layer formed on the surface with the steps; one or more crystals secured to each step; and electrodes positioned on each surface of each crystal.
