Teledyne e2v has announced a family of CMOS image sensors for 3D laser triangulation – for use in applications such as distance measurement, profile measurement and high resolution physical inspection ...

For many centuries, the principle of triangulation - that is the geometric measurement using three-point relationships - has been relatively well known. In Europe, the land survey method established ...

Photoelectric sensors with background suppression are a more evolved version of the basic diffuse sensors used on public washroom sinks to control automatic faucets. Both in this rudimentary ...
