Abstract

We will discuss some physical limits of 3D-sensors that work on ''rough'' surfaces. An important result is that the most frequently used principles (laser triangulation and focus sensing with projected light spots) cannot achieve a better depth resolution than given by the Rayleigh depth of field. However we can achieve ''superresolution'' in depth by sacrificing lateral resolution: There is an ''uncertainty relation'' between lateral and longitudinal resolution. 1 .
