Light detection and ranging system with synchronized scanning mirrors
A recently granted patent (Publication Number: US11828881B2) discloses a light detection and ranging system that utilizes laser light pulses and scanning mirror assemblies to generate a two-dimensional scan pattern over a field of view. The system includes a laser light source, optical devices to form laser light pulses into a fanned beam, a receive aperture, an arrayed receiver with light-sensitive devices, and time-of-flight measurement circuits. The scanning mirror assemblies scan in two axes to direct reflections of the fanned beam onto the light-sensitive devices, allowing for precise detection and ranging capabilities. The system's control circuit synchronously drives the scanning mirror assemblies to ensure the receive aperture continually tracks the fanned beam, optimizing the reception of reflected light energy for accurate measurements.
Furthermore, the patent details variations of the light detection and ranging system, including different scanning mirror motions, laser light source configurations, and arrayed receiver setups. The system can adapt to different dimensional arrays of light-sensitive devices, control scanning mirror movements, and adjust laser light pulse properties based on vehicle sensor data. The system's design allows for efficient scanning of the fanned beam, precise measurement of reflected light energy, and customization of parameters such as pulse width, pulse rate, and pulse power. Overall, the patented technology offers a sophisticated solution for light detection and ranging applications, with potential applications in various fields requiring accurate distance measurements and object detection.
