Model RF651 Operation Principles

The micrometer operation is based on the so-called ‘shadow’ principle. The micrometer consists of two blocks – transmitter, 1 and receiver, 2. Radiation of a semiconductor laser 3 is collimated by a lens 4. With an object, 5 placed in the collimated beam region, shadow image formed is scanned with a CCD photo-detector array 6. A processor 7 calculates the position (size) of the object from the position of shadow border (s).
