A Digital Micromirror Device (DMD) based video projector is used to project sinusoidal fringe patterns onto the object surface. Its red, green and blue (RGB) channels are programmed to be sinusoidal fringe patterns with 120-degree phase difference. The projector has a color filter with four segments, RGB

The work station combines a variety of laser processing techniques onto a single, integrated platform. These techniques include material deposition, laser micromachining, laser sintering, and laser trimming. One particular process, referred to as 'mill and fill', combines the

The principle of focus error detection is based on a method that takes advantage of the focusing properties of simple optical elements. A differential ...
