Laser micrometers are designed for non-contact measurement and control of position and dimensoins (diameter, thickness, gaps) of technological objects as well as for measuring levels of liquid and bulk materials.
RF651 model. Operating principle
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 (borders)
