Abstract: PURPOSE:To improve stability of tracking so as to correctly separate a beam by providing a grating separating the light beam outgoing from a light source into a 0-th order light beam and + or -1st order diffracted beams. CONSTITUTION:A semiconductor laser element 11 is a light emitting element using recombination light emission of a semiconductor, and is used as the light source. The light beam outgoing from the laser element 11 is guided to the grating 12. The grating is used for diffracting an incident light beam and separating the light beam into at least three light beams of the 0-th order diffracted beam and the + or -1st order diffracted beams in the direction of tracking, that is, in the direction perpendicular to the paper surface. A beam splitter 13 is formed into a parallel planar shape, and is arranged in the state where it inclines by 45 deg. to the optical axis of an objective lens 14, and separates the light beam outgoing from the laser element 11 and a return beam from a recording surface of a magneto-optical disk MO. Thus, a dielectric layer 13a consisting of a multilayer film transmitting the P polarization of the light beam and reflecting the S polarization is formed on the surface of the beam splitter 13, and the light beam of the S polarization from the laser element 11 is reflected by the beam splitter 13.

Abstract: PROBLEM TO BE SOLVED: To mitigate influences of disturbance noise caused by a normal light source when obtaining information resulting from light emitted from a separate light source.SOLUTION: An object is irradiated with a specific wavelength wave of a wavelength corresponding to a specific wavelength in which the electromagnetic wave energy level is lower than that of other wavelengths, the specific wavelength wave reflected on the object is detected by a solid-state imaging device 314 and based on obtained detection information, information resulting from the specific wavelength wave is obtained. An optical band pass filter 502 having a band-pass property of narrow bands around the specific wavelength is disposed on an imaging optical route. If object reflection light of the specific wavelength wave is detected, a specific wavelength component is detected without being buried in components of a normal light source. Respective detection information items at a time when the object is irradiated with the specific wavelength wave and at a time when the object is not irradiated with the specific wavelength wave are compared with each other to obtain information resulting from the specific wavelength wave in which influences of disturbance noise caused by the normal light source are mitigated. If the optical band pass filter 502 is used together, only the specific wavelength component can be detected, and even in the case where the quantity of light from the normal light source is strong, without being affected, thereby the problem of saturation can be avoided.
