MEASUREMENT APPARATUS
First Claim
1. A measurement apparatus configured to measure a spectroscopic characteristic of a measurement site in a specimen by applying acousto-optical tomography, the measurement apparatus comprising:
- a measurement unit configured to measure a light intensity of each of measurement areas that are set differently from the measurement site on a light propagation path from the measurement site to a detection position of a light detector; and
a signal processing device configured to sequentially modify the spectroscopic characteristics of the measurement areas and the measurement site on the light propagation path from the detection position of the light detector to the measurement site by using a light intensity that is measured by the measurement unit in the measurement area that is closer to a surface layer of the specimen than the measurement site.

Abstract
A measurement apparatus is configured to measure a spectroscopic characteristic of a measurement site in a specimen by applying acousto-optical tomography. The measurement apparatus includes a measurement unit configured to measure a light intensity of each of measurement areas that are set differently from the measurement site on a light propagation path from the measurement site to a detection position of a light detector and a signal processing device configured to sequentially modify the spectroscopic characteristics of the measurement areas and the measurement site on the light propagation path from the detection position of the light detector to the measurement site by using a light intensity that is measured by the measurement unit in the measurement area that is closer to a surface layer of the specimen than the measurement site.

7. A measurement apparatus configured to measure a spectroscopic characteristic of a measurement site in a specimen by applying photo-acoustic tomography, the measurement apparatus comprising:
-
a measurement unit configured to measure a photoacoustic signal of each of measurement areas that are set separately from the measurement site on a light propagation path from a light incident position to the measurement site; and a signal processing device configured to sequentially modify spectroscopic characteristics of the measurement areas and the measurement site on the light propagation path from the light incident position to the measurement site by using a spectroscopic characteristic of a measurement area that is located in an outermost area closest to a surface layer of the specimen measured by the measurement unit. - View Dependent Claims (8, 9, 10, 11, 12)
