Functions according to the Lateral Effect Photodiode principle. It is an analogue device and therefore displays excellent position resolution. The resolution is determined by the system signal-to-noise ratio. It is operated in the biased mode. Typical applications include: distance and
height measurement, alignment, position and motion measurements and vibration studies
