This product utilizes the Time-of-Flight (TOF) method based on laser pulse measurements to acquire three-dimensional distance information of the target. It achieves sensitivity at the single-photon detection limit and time resolution at the nanosecond level. The detector performs digital quantization of laser pulse flight time within pixels, resulting in a simple signal processing process with minimal noise interference. Additionally, it can generate a complete three-dimensional image of the target in real-time using a single laser pulse, with low required laser power, no need for scanning structures, and no distortion in the images. The system is characterized by its simple structure, compact size, light weight, and low power consumption.
