METHOD AND INSTRUMENT FOR MEASURING TWO-DIMENSIONAL DISTRIBUTION OF TRIBO-PHOTON

摘要

PROBLEM TO BE SOLVED: To provide technology by which the two-dimensional distribution of an ordinary luminous phenomenon which includes an ultraviolet-region photon occurring phenomenon and such a dynamic phenomenon as friction, etc., can be measured with a long working distance and the resolution of an optical microscope by overcoming the weak point of the conventional method that the extent of observation is limited to photons from visible-region photons to near infrared-region photons. SOLUTION: The occurring spot of a phenomenon that occurs on a friction surface is separated by forming a friction contact between two members, by means of a friction forming device and measuring the two-dimensional distribution of the luminous intensity of photons from the vicinity of the friction contact by forming the image of photons from the friction contact on an image forming surface through the objective lens of a microscope, which is positioned near the friction contact and has an ultraviolet-region photon transmitting characteristic.
