Abstract

PURPOSE:To directly measure the absorption characteristics of blood, by providing a pair of flat reflecting plates opposed with a fine gap to the transparent body fitted to the tip of optical fiber with the angle of 90 deg.. CONSTITUTION:The glass transparent body 2 is fitted to the tip of the optical fiber 1 and the incidence and emission of light can be adjusted to the optical fiber 1. Further, a pair of flat reflecting plates 3 are opposed with a fine gap 4 to the transparent body 2 with the angle of 90 deg.. When light is incident to the light transmission fiber bundle, this light is transmitted in the blood 5 in the fine gap 4 through the transparent body 2 and reaches the reflecting plates 3, 3. Since the reflecting plates 3, 3 are opposed with the angle of 90 deg., the reflected light is again in the blood and transmitted to the photodetection system, and the absorption characteristics of the blood to be measured can directly be measured in a short time by analyzing this light.
