摘要： An image display apparatus includes an LD for emitting and modulating visible light, an optical scanning device for two-dimensionally scanning the light from the Ld on a screen in synchronism with the LD, an imaging device for picturizing an image of the image displayed on the screen, and an image processor for judging presence or absence of the pointing element such as a finger or fingers which is/are used to point out an optional position on the image based on temporal change of the image picturized by the imaging device. Even when the finger or fingers of a person is/are used as the pointing element, it is possible to judge the presence or absence of the pointing out of the image by the finger or fingers. Thereby, a number of components can be reduced. In addition, in comparison with an image display apparatus that emits invisible light detects a position of a pointing element corresponding to a photoreception timing of the invisible light reflected by the pointing element, a complex detection circuit having a high time-resolution becomes unnecessary, and it enables to simplify the configuration and to reduce manufacturing cost.

摘要： A temperature of a scanning optical system is different from a temperature of a light source when an optical scanning device is in operation, and when the both temperatures are assumed to be equal, a diffractive surface of a diffractive optical element is set according to a magnitude relationship between both temperatures when the optical scanning device is in operation such that a deviation amount of an in-focus position of the light flux by the diffractive optical element becomes larger or smaller than a deviation amount for canceling a deviation amount of an in-focus position of the light flux by the scanning optical system.

摘要： A method and objective apparatus are provided for implementing an enhanced phase contrast microscope. A focusing vortex lens, defined by a diffractive spiral zone plate (SZP) lens, is used for the objective for the phase contrast microscope. The SZP lens focuses and imparts a helical phase to incident illumination to image the specimen with spiral phase contrast. The spiral phase contrast microscope is sensitive to phase gradients in all sample axes. Replacing the objective of a microscope with the diffractive SZP lens of the invention immediately provides existing instruments with spiral phase contrast capability.

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.

The diffraction surface has a multi-step shape having a plurality of zone surfaces substantially perpendicular to an optical axis and a plurality of step surfaces each adjacent to each of the zone surfaces.
