Abstract:
A non-contact non-invasive measuring method for measurements by previously registering an image indicating a measured portion, the distance between said measured portion and a physical quantity measuring apparatus, and the orientation of said physical quantity measuring apparatus with respect to said measured portion in measurement, and determining the position and the orientation of said physical quantity measuring apparatus through steps of:(A) arranging a measured object in a prescribed space in a non-contact state while arranging positioning means on a sensing position of a probe for sensing said previously registered image of said measured portion with said positioning means and adjusting the position of said probe so that the position of sensed said image coincides with that of said registered image;(B) arranging distance measuring means on said sensing position of said probe and adjusting the position of said probe so that the distance up to said measured portion reaches said previously registered distance;(C) arranging orientation determination means on said sensing position of said probe and determining such a sensing position that said measured portion is in said previously registered orientation; and(D) thereafter arranging said physical quantity measuring apparatus on said sensing position of said probe, moving the same to said position determined by said orientation determination means, thereafter irradiating said measured portion with measuring light from said physical quantity measuring apparatus and sensing output light from said measured portion thereby obtaining a physical quantity.
