Abstract

The ultimate precision of coherent laser three-dimensional mapping of a diffusely scattering surface will be determined by speckle noise. Speckle phase noise gives rise both to apparent range outliers and to excess range noise during lateral scans. Nevertheless at 1 THz optical bandwidth, range precisions below 10 m are achievable.
