    摘要: Disclosed is a non-contacting measuring system relying upon the difference in the focal points of two transmitted, differently modulated, coaxial light bundles. The difference in intensity of the light reflected back from a to-be-measured object located between the focal points of the two light bundles defines the precise location of the object relative to the two focal points.
