Title: LIDAR SYSTEM PROVIDING A CONIC SCAN
Abstract:
Systems and methods of providing a conical LIDAR scan are provided. For instance, a LIDAR system can include one or more light sources configured to emit a plurality of light beams within a wavelength range. The LIDAR system can further include a variable optical element configured to direct the plurality of light beams in a first conical scanning pattern in a direction of a target, the first conical scanning pattern corresponding to a first field of view. The variable optical element includes a reflective material disposed between a fixed end component and a variable end component. The LIDAR system can further include one or more control devices configured to cause an actuation of the variable end component to adjust an angular position of one or more surfaces of the variable optical element.
