Claims

[Scope of utility model registration request]

means for irradiating a plurality of laser beams having mutually different wavelengths onto a subject; a columnar prism for separating reflected laser light from the subject; and a means for separating reflected laser light incident on the prism from a spectral surface of the prism. a plurality of array-like light receiving means arranged in the longitudinal direction of the slit so as to individually extract the laser beams of each wavelength separated by the prism; The slit, prism, and arrayed light receiving means are rotated in a direction substantially perpendicular to the longitudinal direction of the slit while their relative positions are fixed, so that reflected laser beams from different parts of the subject are successively reflected. A living body characterized by comprising: means for making the laser beams incident on a prism; and means for individually obtaining an overall image of the object to be examined using the reflected laser beams of each wavelength from the reflected laser beams taken out by the arrayed light receiving means. Optical diagnostic equipment.
