Abstract
Distance resolutions and noises are analyzed experimentally for long-range
three-dimensional (3D) active imaging systems that have signal-to-noise ratios
(SNRs) more optimal than 30:1. Findings indicate that the photon shot noise
primarily determines the SNR. However, the active imaging method, which has a
relatively low SNR, generates a relatively high distance resolution. To explain this
phenomenon, a theory in which the distance resolution of 3D active imaging systems
is determined by both the photon shot noise and the subinterval width is developed.
Theoretical and experimental results differ by less than 4%.
