Abstract

We describe how to expand the dynamical range of active triangulation systems. The method is based on the expansion of depth of focus, in order to achieve a larger measuring range - and on the reduction of coherent noise, in order to achieve better resolution of depth. With a 1024 element linear photodiode array we could achieve about 15000 resolvable depth positions, in preliminary experiments.
