Abstract: PROBLEM TO BE SOLVED: To enlarge an angle of view to enhance a magnification by enhancing an optical utilization efficiency. SOLUTION: A transmission holographic optical element 104 is joined to a face of a pupil side of a spectacle lens 103. A reflection holographic optical element 105 is joined to the face of the reverse side of the pupil side of the spectacle lens 103. Emission light from an image display element 101 is made to enter the optical element 104 through an optical element 102 so as to be diffracted. Diffraction light is made to enter an optical element 105 through the spectacle lens 103 so as to be diffracted and reflected. Diffraction light (reflection light) is made to enter a pupil 106 of a user through the spectacle lens 103 and the optical element 104. Diffraction can be made to be shared by the optical elements 104 and 105. A large diffraction ability is not required in each of the optical elements 104 and 105, and thus the angle θ of the view can be enlarged to enhance the magnification. Since a half mirror is not used, the optical utilization efficiency can be enhanced. COPYRIGHT: (C)2006,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To increase light usage efficiency and enhance magnification by enlarging an angle of view. SOLUTION: Light emitted from a display device 101 is p-polarized light, and transmission holographic optical elements 104, 105 have diffraction efficiency with respect to these p-polarized lights, respectively. The light emitted from the display device 101 is diffracted at the optical element 104 through an imaging optical element 102, made incident to a prism 103, reflected inside by a predetermined number of times and emitted outside. The emission light obtained by being reflected back with the surface 103c of the prism 103 is further diffracted at the optical element 105, and made incident to pupils 106 of a user. The surface 103c of the prism 103 and the optical element 105 share effect for satisfying total reflection conditions at the surface 103a of the prism 103, so that a large diffraction capability is not required for the optical element 105, thereby increasing a view angle θ. Since a half mirror is not used, the light usage efficiency is increased. The two optical elements 104, 105 are arranged, so that the chromatic aberration caused by diffraction can be offset.

Abstract: PROBLEM TO BE SOLVED: To optimize an optical low-pass filter for reducing a faulty color signal in an optical system having less number of lenses or reducing a faulty resolution. SOLUTION: A cutoff frequency of an optical low-pass filter 120 is higher than a sampling frequency in an image sensor 220 to perform separation of photographed light corresponding to the sampling frequency in the image sensor 220. Further, frequency characteristics obtained by combining the cutoff frequency of the optical low pass filter 120 and a space frequency characteristic of a lens 110 are assumed at a level of 10% or lower or 20% or lower of the sampling frequency in the image sensor 220. Further, in the image sensor in the present example for photographing a color image, the sampling frequency is assumed the pitch of picture elements, while in an image sensor for photographing a monochromatic image the sampling frequency is assumed half the pitch of the picture elements.

Abstract: PROBLEM TO BE SOLVED: To attain the miniaturization of an optical system, the reduction of the number of components and the reduction of the manufacturing cost. SOLUTION: An optical filter element with an optical low-pass filter function of attenuating light having a specific wavelength can be positioned and held by an image pickup image forming element itself with a function of forming an object image on a photoelectric conversion element (solid-state image pickup element). Then, adhesive and a fixing member for fixing the optical filter element are dispensed with, and then, the miniaturization of the optical system, the reduction of the number of components and the reduction of the manufacturing cost are attained. Besides, as for the image pickup optical system and the image pickup camera apparatus, the deterioration of an image forming performance due to the deviation of a distance between an optical diaphragm and the image pickup image forming element caused by the tolerance dimensional error of the optical filter element is easily corrected in the case of assembling the optical filter element equipped with the optical diaphragm and the image pickup image forming element into a lens barrel part.

When rotating operation is stopped at an optimum focusing position, the projected part 14 is made in an engaged state with the recessed part 23. The projected part 14 does not fall off from the recessed part 23 in this state unless strong force is applied, so that the engaged state is held.

Abstract: PROBLEM TO BE SOLVED: To provide an optical isolator element making an isolation angle of return light large by using a maximum refractive index of a uniaxial crystal for abnormal light and an optical pickup using the optical isolator element. SOLUTION: The optical isolator element is constituted of two prism blocks 16a, 16b arranged so as to hold a dielectric mutilayer film 16c between them, and a first prism block 16a is a glass prism consisting of glass, and a second prism block 16b is a uniaxial crystal prism consisting of uniaxial birefringent material. Then, the optical axis of the uniaxial crystal prism is tilted by an angle so that a difference between refractive indexes for a normal light component and an abnormal light component becomes maximum for the optical axis of the return light beam containing a magneto-optical component made incident through a polarized light isolating film or an adhesive layer. Further, the optical isolator element 16 is constituted so that the optical axis of the uniaxial crystal prism is arranged in a surface having a prescribed angle for the polarization direction of the incident return light beam.
