BACKGROUND OF THE INVENTION Devices are already known that combine a light guide for transmitting illumination light and an image fiber for transmitting images in order to see hidden parts of objects or living organisms that cannot be viewed directly. For medical purposes, it is generally called an endoscope. However, since conventional endoscopes only allow visual inspection, it is not possible to accurately determine abnormalities in visible living tissue, and even if an abnormality is noticed, it is not possible to determine the extent of the abnormality.

SUMMARY OF THE INVENTION An object of the present invention is to provide an apparatus that can detect an abnormality and the degree of the abnormality by measuring the anti-spectral spectrum of the visible portion in order to compensate for such drawbacks.

の像を結像する。 In the figure, illumination light emitted from a white light source 1 is guided by a light guide 3 of a transmission section 2 and is emitted from the tip of the transmission section 2. The reflected light from the object 4 of the illumination light is reflected by the imaging unit 5.
The light is incident on the image fiber 6 of the transmission section 2 through the rays. That is, an image of the object is formed on the tip of the image fiber 6.

TVに表示される。 The reflected light from the object is guided to the base end of the image fiber 6 through the image fiber 6, and is then directed to the image receiving section 7.
The light is emitted through the camera and is imaged on the TV camera 8. A light branching mirror 9 is provided between the image receiving section 7 and the TV camera 8, and the light emitted from the image fiber 6 is branched and input to a spectrometer 10, so that the reflection spectrum of the object can be obtained. The reflection spectrum is determined by the control unit 11.
The data are analyzed by the arithmetic processing unit 12 in accordance with instructions from the computer. The image of the object obtained by the TV camera 8 and the spectroscopic analysis result of the object obtained by the arithmetic processing section 12 are monitored in accordance with instructions from the control section 11.
