Title:
LASER RADAR TRANSMITTING MODULE, TRANSCEIVER DEVICE AND LASER RADAR
Document Type and Number:
WIPO Patent Application WO/2024/045550
Kind Code:
A1
Abstract:
A laser radar transmitting module, a transceiver device and a laser radar. The transmitting module comprises: a multi-wavelength light emitting unit, the multi-wavelength light emitting unit being suitable for generating a light beam; a wavelength switching unit, the wavelength switching unit receiving the light beam generated by the multi-wavelength light emitting unit, and the wavelength switching unit controlling, by means of an electrical signal, a plurality of switching elements to switch the wavelength of the output light beam; and a light splitting unit, the light splitting unit being located in an optical path downstream of the wavelength switching unit, and the light splitting unit being used for splitting the received light beam and enabling each obtained beam to further form multi-line detection light. By means of an electrical signal, switching elements (i.e., an optical switch) are controlled to switch the wavelength of the output light beam, thereby effectively reducing the manufacturing process difficulty of the wavelength switching unit, and effectively reducing the control difficulty of achieving high-speed wavelength switching.
