Title:
LASER PULSE TRANSMISSION DEVICE, LASER MEASUREMENT DEVICE, AND MOBILE PLATFORM
Document Type and Number:
WIPO Patent Application WO/2018/176286
Kind Code:
A1
Abstract:
A laser pulse transmission device (100), a laser measurement device, and a mobile platform. The laser pulse transmission device (100) comprises a pulse transmission circuit (110) and an overvoltage protection circuit (130). The pulse transmission circuit (110) comprises a laser transmitter (111) and a driver (113). A first end of the laser transmitter (111) is used for being connected to a power supply and a second end of the laser transmitter (111) is electrically connected to the driver (113). The laser transmitter (111) is used for transmitting a laser pulse when the driver (113) is started. One end of the overvoltage protection circuit (130) is electrically connected to the second end of the laser transmitter (111), and the other end of the overvoltage protection circuit (130) is electrically connected the first end of the laser transmitter (111) or grounded. The overvoltage protection circuit (130) is used for reducing a high-voltage transient pulse generated by the laser transmitter (111). The laser pulse transmission device (100) can effectively reduce the high-voltage transient pulse generated by the laser transmitter (111).
