  • Patent number: 11808891
    Abstract: Methods and systems for performing three dimensional LIDAR measurements with an integrated LIDAR measurement device are described herein. In one aspect, a Gallium Nitride (GaN) based illumination driver integrated circuit (IC), an illumination source, and a return signal receiver IC are mounted to a common substrate. The illumination driver IC provides a pulse of electrical power to the illumination source in response to a pulse trigger signal received from the return signal receiver IC. In another aspect, the GaN based illumination driver IC controls the amplitude, ramp rate, and duration of the pulse of electrical power based on command signals communicated from the return signal receiver IC to the illumination driver IC. In a further aspect, illumination driver IC reduces the amount of electrical power consumed by the illumination driver IC during periods of time when the illumination driver IC is not providing electrical power to the illumination source.
