Claim 7:
8. The LiDAR transmitter according to claim 1, wherein the M-path phase shifter array comprises an M-path phase shifter, the mth (m=1, 2, . . . , M) path phase shifter is connected with the mth path output port of the N×M optical beam expanding network, the M-path phase shifter array performs phase shift on an input optical signal, so that the phase of the output signal has an equal difference relationship, and the equal difference quantity is continuously tunable; and the M-path phase shifter is a phase shifter based on a thermo-optic effect or an electro-optic effect, and the phase tuning range of the phase shifter is 0-2π.
