Lidar system with variable rate laser pulse scheduling
The patent US12050286B2 describes a lidar system that integrates a laser source and a scannable mirror to enhance the efficiency and effectiveness of laser pulse shots directed at specific range points within a field of view. The system features a circuit that schedules the firing of laser pulse shots at a variable rate, utilizing a laser energy model that accounts for energy retention in the laser source after each shot. This model quantitatively predicts the available energy for upcoming shots based on the history of prior firings, ensuring that the energy requirements for each shot are met. The mirror can operate in a resonant mode, scanning through various angles to direct the laser pulses accurately.
Additionally, the system incorporates a mirror motion model that helps determine the timing and angles for the laser pulse shots, allowing for precise targeting of range points defined by specific coordinates. The circuit can simulate different shot order candidates to optimize the scheduling of laser shots based on energy availability and mirror motion. The lidar system also considers safety requirements for both eye and camera protection, ensuring compliance during operation. The technology is designed to improve the performance of lidar applications by efficiently managing energy resources and enhancing the accuracy of laser targeting through advanced scheduling and modeling techniques.
