WebAbstract. We present a real-time spectral-scanning frequencymodulated continuous wave (FMCW) 3D imaging and velocimetry system that can produce 3D depth maps at 33 Hz, with 48°×68° field of view (FOV) and 32.8-cm depth range. Each depth map consists of 507×500 pixels, with 0.095°×0.14° angular resolution and 2.82-mm depth resolution. WebAbstract: An analysis of coherent optical FMCW is presented. It shows the limitations imposed on measurements of discrete reflections and of Rayleigh backscattering due to phase noise originating in the finite coherence length of the optical source.
