    • A photometer comprises a projecting mechanism irradiating a physical mass with infrared light within a wavelength region of 1.1 to 2.0 &mgr;m, a photoreceiving mechanism receiving output light from the physical mass and a spectroscope separating the light applied to the physical mass or the output light from the physical mass into its spectral components, for measuring absorbance by the physical mass at a specific wavelength. A compression mechanism can compress a measured region of the physical mass or a peripheral portion thereof, and difference absorbance calculator obtains difference absorbance from first absorbance obtained by the photometer under a state compressed by the compression mechanism with a first pressure and second absorbance obtained by the photometer under a state compressed with a second pressure lower than the first pressure or a non-compressed state. A storage part stores a relation between body fat and difference absorbance, and an operation part quantitatively determines and outputs body fat from the difference absorbance calculated by the difference absorbance calculator on the basis of the relation stored in the storage part.

    • A second optical component is an optical fiber bundle charged in a clearance between an inner cylinder and an outer cylindrical outer peripheral part in the form of a ring. These elements are integrated with each other, and forward-end-surfaces thereof are on concentric circles. A ring of the forward-end-surface of the outer peripheral part is larger in width than the ring of the forward-end-surface of the second optical component. A first optical component charged with an optical fiber bundle is slidably inserted into and engaged in the cylinder inside the second optical component, so that the forward-end-surface of the first optical component can project or retract from the forward-end-surface of the outer peripheral part. The outer peripheral part is brought into contact with a human body and force for pressing a measured region is changed by sliding the first optical component for measuring absorption spectra between the first and second optical components under different values of pressing force, thereby obtaining a difference absorbance spectrum under different states of pressurization.
    • 第二光学部件是以环形的内筒和外筒部外周部之间的间隙充填的光纤束。 这些元件彼此集成,其前端表面在同心圆上。 外周部的前端面的环的宽度比第二光学部件的前端面的环宽。 装有光纤束的第一光学部件可滑动地插入第二光学部件内并与其接合,从而第一光学部件的前端表面可以从第一光学部件的前端表面突出或缩回 外围部分。 使外周部与人体接触,通过在不同的按压力下滑动用于测量第一和第二光学部件之间的吸收光谱的第一光学部件来改变测量区域的按压力,从而获得差异吸光度 频谱在不同的加压状态。
