RF600 - large-base and long range sensors
Operation of the sensors is based on the principle of optical triangulation. 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 CCD-array 4. A signal processor 5 calculates the distance to the object from the position of the light spot on the array 4.
