<p>A light beam is applied from a light source to an object portion such as an affected portion.From the light reflected from the illuminated object portion,at least two wavelength regions,i.e.,the wavelength region specific to the light source and the wavelength region specific to the object portion are selected.The two wavelength regions include the wavelengths at which the intensities of light take on maximum values.The relative intensities of light in the two wavelength regions are quantitatively determined by spectroscopic measuring means.The values obtained by the quantitative determination are outputted in the form of electric signals so as to control means.Thus,an object portion such as an affected portion is quantitatively judged,detected,and treated or sampled.</p> |
