摘要： A measurement apparatus includes a dielectric block, a thin film layer formed on the dielectric block and brought into contact with a sample, a light source for generating a light beam, an optical incident system for causing the light beam to enter the dielectric block so that the light beam is totally reflected at the interface between the dielectric block and the thin film, and a two-dimensional light detection means for detecting the intensity of the light beam totally reflected at the interface. A predetermined pattern is formed within a region irradiated with the light beam on the dielectric block. The measurement apparatus includes a correction means for correcting an output from the two-dimensional light detection means, based on the pattern, so that an object on the face of the dielectric block is similar to the object detected by the two-dimensional detection means.

The recording layer comprises a material, which has properties such that, when recording light having a predetermined wavelength λ1 is irradiated to the material, the material is capable of being caused to change into a fluorescent material and such that, when excitation light having a wavelength λ2 is then irradiated to the thus formed fluorescent material, the fluorescent material is capable of being caused to produce fluorescence. The wavelength λ1 of the recording light and the wavelength λ2 of the excitation light may be identical or different. The substrate may be constituted of a material having properties such that, when the excitation light is irradiated to the material, the material does not produce fluorescence having a wavelength identical with the wavelength of the fluorescence produced by the fluorescent material.

摘要： A small-sized measuring apparatus having a stray light suppressing capability for detecting the distribution of optical intensities on the cross section of a light beam having a predetermined wavelength contained in a light beam reflected from a measuring surface by entering a collimated light beam having a large cross sectional area into the measuring surface. A collimated light beam having a sufficient cross sectional area is entered into the interface between a dielectric block and a thin metal film formed on the dielectric block at an angle that satisfies the conditions of total reflection. A light beam having a predetermined wavelength is selected from the light beam totally reflected at the interface to detect the distribution of optical intensities for the selected light beam by the wavelength selecting section capable of eliminating stray light.

The sensor also includes an optical system for making the light beam enter the dielectric block at angles of incidence so that a total internal reflection condition is satisfied at an interface between the dielectric block and the thin film layer. The sensor further includes a sample supply-discharge unit which is detachably installed within the measuring chip. The sample supply-discharge unit is used for continuously supplying the sample onto the surface of the thin film layer and continuously discharging the supplied sample from the surface of the thin film layer.
