a, Imaging contrast measured using retroreflective sheeting. Our system achieves >25 dB contrast for a one-pixel displacement, >50 dB contrast for a four-pixel displacement, and reaches the system noise floor thereafter, illustrating the excellent pixel-to-pixel isolation in our system. Here, the error bars represent the standard error. b, Depth precision and detection probability as a function of distance for a 44% reflectance target. The error bars on the depth precision represent the 95% confidence intervals. c, d, Single-chirp (c) and multi-chirp (d) FMCW waveforms, used for measuring slow and fast objects, respectively. e, f, Measured velocity as a function of rotation rate for a 30-cm-diameter styrofoam cylinder at a distance of 17 m using single-chirp (e) and multi-chirp (f) waveforms, with error bars indicating the standard deviation.
