ELECTRO-OPTICAL DEVICE FOR CONSTANTLY MONITORING THE MUTUAL SPATIAL RELATIONSHIP OF TWO MACHINES OR MACHINE PARTS

摘要

An electro-optic device for constantly monitoring the relative position of two machines or parts of machines has in a known manner a beam transmitter (10) that transmits a light beam (L) and a light receiver (11) which receives the light beam in conditions depending from the relative position of the machines or parts of machines and generates electric signals with position parameters processed in a computer from which various data partially deduced from the position parameters can be requested. An electric signal with an intensity parameter is obtained from the position parameter signals. The intensity parameter is applied in the computer (15) for cyclically requesting the data obtainable from the computer, thus allowing an easy remote operation of the data requests by arbitrarily interfering with the light beam (L) or with the reflected light beam (L').
