Abstract :
In this work, an optical configuration is proposed to increase the spatial resolution of triangulation based profilometers utilising digital video projection (DVP) and also facilitate increased performance of defocusing optimisation schemes. The performance of the proposed optical configuration by contrasting experimental results obtained from a typical triangulation based profilometer optical configuration is demonstrated
