Extended Data Fig. 7 | Channel-by-channel analysis of proof-of-concept
lidar demonstration. a, Time-frequency maps obtained with short-time
Fourier transform of the delayed homodyne beat detection of the individual
FMCW channels back-ref lected from the rotating f lywheel. Top left to bottom
right panels denote optical carriers between 192.1 THz and 195.2 THz.
The pump channel at 193 THz is outlined in purple. Modulation frequency is
100 kHz. b, As for a, but for static flywheel.
