摘要： A viewing optical system for display devices or an image pickup optical system, which can be used with high efficiency at a plurality of wavelengths and enables bright images to be viewed with satisfactory color reproducibility and well-corrected aberrations. The optical system comprises a first prism, a second prism and a volume hologram element disposed between them and cemented to them. The hologram element comprises a first volume hologram optimized in such a way as to effect diffraction at least at a first wavelength and a second hologram optimized in such a way as to effect diffraction at a second wavelength different from the first wavelength. The first and second holograms are identical with each other in terms of the shape and spacing of interference fringes on their surfaces but different from each other in terms of the spacing and tilt of interference fringes in their hologram media.

摘要： An optical system invention is interposed between a pupil plane and an image plane, and includes a first prism, a second prism, and a holographic element which is sandwiched between the first prism and the second prism and is cemented to these prisms. When a light beam traveling along the optical path connecting the pupil plane and the image plane through the optical system is called a first beam, the first prism has a 1-1 surface placed on the pupil side, combining the function of transmission with the function of reflection of the first beam; a 1-2 surface placed on the opposite side of the pupil with respect to the 1-1 surface; and a 1-3 surface placed on the image side, transmitting the first beam. The second prism includes a 2-1 surface having the same shape as the 1-2 surface and placed opposite thereto, transmitting the first beam at least twice, and a 2-2 surface placed on the opposite side of the pupil with respect to the 2-1 surface of the second prism, reflecting the first beam. The holographic element is designed so that the first beam, when entering the holographic element at a first incident angle, is diffracted and reflected and when entering the holographic element at a second or third incident angle, is transmitted.

摘要： An observation optical system or a photographing optical system comprises, between a pupil surface and an image surface, a first prism 3 and a second prism. The first prism 3 includes a 1st-1st surface 31 which has both of actions of transmitting and reflecting light in the path, a 1st-2nd surface 32 which has both of actions of reflecting and transmitting the light in the path, and a 1st-3rd surface 33 which transmits the light in the path. The second prism 4 includes a 2nd-1st surface 41 which is disposed adjacent to the 1st-2nd surface 32 at an air space away and which transmits the light in the path at least twice and a 2nd-2nd surface 42 which reflects the light in the path. The 1st-1st surface 31 is constructed of a prism face to which a volume hologram 6 is applied. Whereby, the observation optical system or photographing optical system can be made compact and lightweight enough to be incorporated into a portable telephone, a portable intelligent terminal, or a virtual-image observation system, and can provide bright images with high resolution.

摘要： The invention relates to a slimmed-down yet high-performance image display device which comprises a decentered prism capable of internal reflection and a reflection type image display device such as a reflection-type LCD or DMD and can present bright images to an observer, and provides an image display apparatus comprising a light source 5, a reflection type image display device 3, and an ocular optical system for guiding an image displayed on device 3 into an eyeball position for forming an intermediate image 4. The ocular optical system comprises a prism member 10 comprising an entrance surface 11 and two reflecting surfaces 12 and 13. In a prism, an optical path for connecting the first surface 11 with the second surface 12 intersects a reflecting optical path from the third surface 13. The ocular optical system further comprises a back-coated reflecting surface 23 between the third surface 13 and an observer's eyeball side. The first surface 11, second surface 12 and third surface 13 are located between the image display device 3 and the intermediate image 4. The second surface 12, third surface 13 and back-coated reflecting surface 23 are each formed into a rotationally asymmetric surface shape capable of imparting power to a light beam and making correction for decentration aberrations. Illumination light is incident from the third surface 13 on the image display device 3 to illuminate the same.
