Object size interferometric determination enabling method, involves deriving size of object by interferometric measurement of distance between one reflector unit and test point in tracking unit

摘要

The method involves reflecting interferometric measuring beam from reflector units in a housing, and conveying reflected beam to a tracking unit`s (21`) interferometer. Housing is positioned as a tactile barb of positioning unit at an object, under consideration of forces and moments effected on the housing. Object size is derived by interferometric measurement of distance between the reflector unit and a test point in the unit (21`). The positioning unit forms a tactile object sensor. Independent claims are also included for the following: (A) an interferometric measuring unit including an automation system for determination of size of an object; (B) a measuring station including an interferometric measuring system for determination of size of an object; and (C) an application of interferometric measuring system for determination of size of an object.
