Calibration method of object length and apparatus for calibration object length

摘要

contactless calibration of the subject, in particular the terminal merek (1) uses the white light which is guided to the detector (11) so that the part of the reflected from the first cell (1), the end merkypart of the pass around the end merky (1) and a part of which is used as a referencnu00ed ricocheted off the other end merky cell (1).another part of the white light from the same source (2) of light is like referencnu00ed conducted to the detector (11) with a reflection from the sliding reflective surface (10).a sliding reflective surface (10) is changing the length of the runway referencnu00edho svetelnu00e9ho volume, while with the zjiu0161tuju00ed conditionswhen is the length of the referencnu00edho volume shall be the length of the track beam svetelnu00e9ho odrau017eenu00fdch lights from the first and second cell end merky (1) and of the light prechu00e1zeju00edcu00edho around the end merky (1).in the position of the sliding reflective surface (10) in which the equality of length pathways occurs due to the detector (11) to increase the svetelnu00e9ho signalbecause only by identical wavelengths of light at the detector misfortunes bundles (11) in the same phase.by comparing the distance vertically sliding reflective surface (10) in a state of reinforced beam of light at the detector (11) determines length of end merky (1).
