Structure and operational principle
Operation of the sensors is based on the principle of optical triangulation
(Figure 1). Radiation of a semiconductor laser (1) is focused by a lens (2) onto an
object (6). Radiation reflected by the object is collected by a lens (3) onto a linear
CMOS array (4). Moving the object (6 - 6') causes the corresponding shift of the
image. A signal processor (5) calculates the distance to the object from the
position of the light spot on the array (4).
