Title:
光測定装置
Document Type and Number:
Japanese Patent JP4304710
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To display images at any arrangement position, without limiting an arrangement position of light transmission/detection points in a light-measuring apparatus and without being affected by a position relationship between an absorption (or absorption change) part inside of a body to be tested and the light transmission/detection point. SOLUTION: This light-measuring apparatus has a light transmission/detection means 2 for illuminating the body to be tested with a light from a plurality of light transmission points and detecting the light passing the body to be tested at a plurality of light detection points, a light intensity signal-measuring means 3 for measuring the light intensity signals of light signals detected by the light transmission/detection means, a sensitivity distribution-forming means 4 for forming for each set of the light transmission and the light detection points of the plurality of light transmission and light detection points a sensitivity distribution showing for each position in the body to be tested a weight to the light intensity signals, and an image-forming means 5 for operating image signals showing an internal state of the body to be tested with the use of the light intensity signals and the sensitivity distributions. The internal state of the body to be tested is displayed by images using the image signals obtained by the image-forming means 5.
