摘要： [Object] A measurement method and an evaluating apparatus are provided which are capable of easily and accurately evaluating the light amount of a spot beam, the diffraction efficiency, and the intensity distribution in the optical axis direction by detecting even a weak diffracted beam in an arbitrary wavelength range converged by a diffraction optical element as an imaging lens.[Means for Attaining the Object] Light emitted from a white light source 11 passes through a wavelength band-pass filter 12 and is diaphragmed by a pinhole slit 13. The resultant light is paralleled by a collimator lens 14 and enters a diffraction optical element 16 as an imaging lens. The light getting out from the diffraction optical element 16 is converged to be a spot beam 17, is magnified by a microscope 18, and is then projected on a CCD 19. A distance changing member 56 changes the distance between the CCD 19 and the diffraction optical element 16, and then, the intensity distribution in the optical axis direction is measured. In-plane intensity distribution perpendicular to the optical axis is also measured.

摘要： In a method for forming an image of a subject on a solid-state imaging device, a first time period for splitting a light beam from a subject into a plurality of light beams that have different polarization directions and then combining the plurality of light beams to form a single subject image on the solid-state imaging device and a second time period for splitting the light beam from the subject into the plurality of light beams that have different polarization directions and forming a plurality of subject images that overlap each other partially on the solid-state imaging device are switched time-wise. A first image information on the single subject image is obtained based on pieces of signal information in the first time period, and a second image information on one of the plurality of subject images is calculated by using and computing pieces of signal information in the second time period. Then, the high-resolution image of the subject is achieved by using the first image information and the second image information. In this way, it is possible to obtain an image with a high resolution and a reduced noise with substantially no loss of the light beam from the subject.
