A lidar system with enhanced performance - A simplified explanation of the abstract
This abstract first appeared for US patent application 18154880 titled 'A lidar system with enhanced performance
Simplified Explanation
The abstract describes a LIDAR system that includes a transmitter, receiver, and processor.
- LIDAR system: transmitter, receiver, processor
- Transmitter directs illumination pulses towards a scene
- Receiver includes an array of photodetectors that receive reflected optical radiation from the scene
- Photodetectors output signals in response to the received optical radiation
- Shutter modulates the signals using a chirp shutter function with a selected chirp period
- Readout circuit samples and digitizes the modulated signals in multiple sampling windows spanning the chirp period
- Processor selects sampling windows for the photodetectors
- Processor processes the digitized signals in the selected sampling windows
- Depth map of the scene is generated based on the processed signals.
Original Abstract Submitted
A LIDAR system includes a transmitter, a receiver, and a processor. The transmitter directs a sequence of illumination pulses toward a scene. The receiver including an array of photodetectors, which receive optical radiation reflected from the scene and output respective signals in response to the received optical radiation, a shutter which modulates the signals output by the photodetectors by applying a chirp shutter function, having a selected chirp period, to the signals, and a readout circuit, which samples and digitizes the modulated signals in each of a plurality of sampling windows, which span the chirp period, thereby generating a corresponding plurality of digitized output signals. The processor selects respective sampling windows for the photodetectors, and processes the digitized output signals in the selected respective sampling windows to generate a depth map of the scene.
