Integrated lidar device with common optical path and beam splitter
A recently granted patent (Publication Number: US11860280B2) discloses an integrated Light Detection and Ranging (LIDAR) device that combines various components to enable accurate distance measurement. The device includes an illumination source, detector, illumination driver, beam splitter, and collimating optical element, all mounted on a substrate. The illumination source generates a measurement beam of light, while the detector detects the return beam of light and generates an output signal. The return beam and measurement beam share a common optical path within the device. Additionally, the device features an amplifier, analog to digital converter, and processor for signal processing to determine the time of flight of the measurement beam in the environment.
Furthermore, the patent describes a method for operating the integrated LIDAR device, involving generating and detecting light beams, separating the return beam, and collimating the measurement beam. The method includes amplifying and converting the output signal to a digital signal for further processing. Various configurations of the beam splitter, detector, and illumination source are detailed, highlighting the device's versatility and potential applications. The patent also mentions an integrated LIDAR system with a rotatable board to enhance the device's functionality. Overall, the patent showcases a comprehensive approach to LIDAR technology, offering a compact and efficient solution for distance measurement in various environments.
