Abstract
A system and method for scanning an amplitude modulated transmitted beam through a 360° FOV. The method includes generating a laser beam to be transmitted, intensity modulating the laser beam at multiple modulation frequencies, directing the laser beam to a spiral phase plate resonator (SPPR) device, directing a transmitted beam from the SPPR device onto a conical mirror to direct the transmitted beam at a certain angle therefrom depending on the frequency of the laser beam and processing a return beam.
