  • Electro-optical measuring device for determining the relative position of two bodies, or of two surface areas of bodies, in relation to each other
    Patent number: 6040903
    Abstract: Proposed for detecting the relative position of two bodies (2, 3) or surface regions of bodies is an electro-optical measuring instrument which has, in a known way, a light beam transmitter (4), which can be attached to the one body (3) or surface region and transmits a focused light beam (L), and a single-axis or multi-axis optoelectronic position detector with a light-sensitive measuring surface (5). During measurement of the bodies (2, 3) or surface regions, the light beam (L) impinges on the measuring surface (5), and its point of impingement (LA) moves over the light-sensitive surface (5), during execution of a measuring movement, in a way which is characteristic of the current mutual alignment of the bodies (2, 3) or surface regions.
