Laser-based vernier calliper gauge:
enables contact-less measurements
The calliper gauge described in this article is not an optoelectronic device, although it is based on the marriage of a laser (optics) and electronics. It is an excellent example of the way optics and electronics can be made to work together. Like its mechanical counterpart, it is very accurate, gives fast results and need not touch the object to be measured.
