摘要

PROBLEM TO BE SOLVED: To obtain a physical property value at an arbitrary point in an aggregate by making an aggregate contain a fluorescent substance for indicating an up conversion, applying two types of wavelengths in different directions, crossing them for detecting emission characteristics, and comparing them with reference characteristics. ;SOLUTION: The measuring device is provided with a light application means consisting of light sources of two types of wavelengths consisting of a pulse light source 1 with a wavelength 1 and a pulse light source 2 with a wavelength 2, a means for applying light from both the light sources to a transparent aggregate from a different direction, a laser synchronization signal control means for changing the application timing of the pulse light sources 1 and 2, and a means for detecting emission characteristics. For means for applying light from light sources with two types of wavelengths from different directions so that they cross the aggregate, for example a movable mirror A corresponding to light from the light source 1, a fixed mirror C and a movable mirror B corresponding to light from the light source 2 are used. These mirrors are controlled by a mirror drive control signal so that incidence light crosses at the arbitrary measurement point of a three-dimensional shape.;COPYRIGHT: (C)2000,JPO
