Title:
LASER RADAR RANGING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/004610
Kind Code:
A1
Abstract:
A laser radar ranging system, comprising: a photoelectric sensor (101), a differential driver (102), a collection unit (103), a control unit (105) and a processing unit (104), wherein the photoelectric sensor (101) is electrically connected to the differential driver (102), the differential driver (102) is electrically connected to the collection unit (103), the collection unit (103) is electrically connected to the processing unit (104), and the control unit (105) is electrically connected to the differential driver (102); and the differential driver (102) is used for receiving an analog signal and a first reference signal, converting the analog signal into a digital signal on the basis of a first threshold voltage value, and sending the digital signal to the collection unit (103). By means of the system, the influence of a laser test error brought about by non-linearity can be reduced, thereby reducing the power consumption cost of a ranging circuit, and improving the reliability while also improving the laser ranging precision.
