Abstract

There are many applications involving the detection of an area or edge of a moving mechanical member where an optical reflective sensor would integrate perfectly. However, implementation of reflective sensor systems is sometimes difficult, particularly in a direct couple mode because of the sensor's wide parameter range and the difficulty of obtaining a large signal-to-noise ratio.
