In scan-based 3-D systems, the achievable measurement time is strongly restrained by the
moving mass. This limitation can be relaxed, by scanning the optical path instead of moving …

In scanning laser triangulation sensors for 3D imaging, the achievable throughput is strongly
limited by the moving mass. By realizing an optical scanning approach rather than …

Mechatronic imaging systems, ranging from nanoscale metrology to telescope systems and
adaptive optics for astronomy, are complex machines that demand continual improvement of …

A confocal displacement sensor with a varifocal lens and a multi-wavelength rainbow laser
