ABSTRACT:
An optical system is arranged to irradiate light to the inside of a test subject and detect the light passed through the test subject for obtaining information about the inside of the test subject. The optical system includes a light source for generating rays of light having different wavelengths, an apparatus for irradiating the rays of light to corresponding spots on the test subject, an apparatus for detecting the light passed through the test subject at plural detecting spots on the test subject, and an apparatus for dispersing the detected light. The rays of light to be irradiated to the test subject have a visible wavelength to a near infrared one. The apparatus for irradiating light operates to irradiate the rays of light of each of the wavelengths to the test subject substantially at one time or by shifting the irradiating times according to each of the wavelengths. The apparatus for irradiating light contains the apparatus for dispersing the irradiated light into respective wavelengths. The rays of light dispersed by the dispersing apparatus are irradiated to the test subject.
