Abstract:
1. An optical measuring apparatus for measuring characteristics of a test section using light emitted from a light source, wherein the apparatus comprises: an optical element with multitudes of inorganic fluorescent nanoparticles dispersed therein, the fluorescence energy level of the nanoparticles being controllable by the diameter thereof; an excitation light source for emitting excitation light with a wavelength in the wavelength range capable of photoexciting the fluorescence energy level of the inorganic fluorescent nanoparticles; a branching/combining means for branching the light emitted from the light source into measuring light and reference light, irradiating the measuring light on a test section, and interfering reflected light of the measuring light reflected from a predetermined depth of the test section with the reference light; a measuring means for measuring the light intensity of the interference light produced by the reflected light and reference light; and an image generating means for obtaining an optical tomographic image of the test section based on the light intensity of the interference light obtained by the measuring means.
