1. An examination apparatus for measuring the oxygenation in an object with electromagnetic wave transmission spectrophotometry, comprising:
- light source means for sequentially emitting electromagnetic waves with different wavelengths;
an illumination-side fixture for making said electromagnetic waves introduced from said light source means incident on a measuring object and detecting reflected electromagnetic waves from said measuring object;
reflection light detection means for detecting said reflected electromagnetic waves introduced from said illumination-side fixture and outputting reflection light data;
output light detection means for detecting emitted electromagnetic waves from said light source means and outputting output light data; and
a computer system for receiving said reflection light data from said reflection light detection means and output light data from said output light detection means, and judging whether a fitting position of said illumination-side fixture has been changed on the basis of said reflection light data and said output light data.

Abstract
An examination apparatus measures the oxygenation of body organs by using the near infrared transmission spectrophotometry. To assure the measurement reliability and the object person'"'"'s safety, the examination apparatus monitors the variation of the fitting position of an illumination-side fixture by detecting the reflection light quantity from the measuring object.
