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. The system employs a grating for beam steering and a telescope for angular FOV magnification. Quantitative depth, reflectivity, and axial velocity measurements of a static 3D printed depth variation target and amoving robotic arm are demonstrated.
