ABSTRACT:
The apparatus uses a laser, the beam of which crosses the working space of the machine element. A photo detector that is sensitive to the position of the laser beam is located in a measuring head connected to the machine element and is connected with a computer for signal processing. The photo detector is preceded by a beam splitter for the laser beam, which deflects the split portion of the beam and sends it to a second photo detector sensitive to the position of the laser beam, which is also connected to the computer.
