A phased array lidar includes: a laser generator () configured to generate original laser; an optical transmitting medium (); an optical splitting apparatus () coupled to the laser generator () through the optical transmitting medium (); the optical splitting apparatus () including a device configured to receive the original laser; and Z radiation units (), each being respectively coupled to the optical splitting apparatus (), where Z is a natural number greater than 1. The optical splitting apparatus () is configured to split the original laser into Z first optical signals, and send each of the Z first optical signals respectively to the radiation units (), so that electromagnetic waves radiated by all of the radiation units () are combined into a beam of radar waves. The laser generator (), the device, and the optical transmitting medium () are made of a material capable of transmitting laser having power greater than a set power value.

Optical phased array lidar

A pToF sensor, a pToF pixel array and an operation method therefor are provided. The pToF pixel array includes a plurality of pToF pixels distributed in an array, a control circuit, and a conversion circuit. Each of the pToF pixels includes a photo sensitive unit configured to detect a return signal of a light pulse signal, and a first conversion unit configured to convert a time signal corresponding to each of the pToF pixels to an analog signal. The control circuit is connected to each of the pToF pixels, and configured to control an operation mode of each of the pToF pixels. The conversion circuit is connected to each of the pToF pixels, and configured to calculate a time-of-fight corresponding to each of the pToF pixels according to the analog signal corresponding to each of the pToF pixels.
