摘要： A compact, thin and low-cost image-forming optical system having an optical low-pass filter, and an apparatus using the image-forming optical system. The image-forming optical system for forming an image of an object includes a stop (2), a first prism (10) placed closer to the object side than the stop (2), and a second prism (20) placed closer to the image side than the stop (2). The first prism (10) has object-side reflecting surfaces (12, 13) with an aspherical surface configuration that reflect a light beam in the prism and give a power to the light beam when reflecting it. The second prism (20) has image-side reflecting surfaces (22, 23) with an aspherical surface configuration that reflect a light beam in the prism and give a power to the light beam when reflecting it. A low-pass filter (4) for cutting off a high-frequency component is provided between the object-side reflecting surfaces (12, 13) and the image-side reflecting surfaces (22, 23).

摘要： A decentered prism optical system has a first surface at a side thereof closer to a pupil. The first surface has a transmitting or reflecting action and also has a wide effective area. The first surface is formed from a rotationally symmetric spherical or aspherical surface. The optical system has at least three surfaces (3, 4 and 5), and the space between these surfaces (3 to 5) is filled with a transparent medium having a refractive index larger than 1.3. A bundle of light rays from an object first passes through a pupil (1) of the optical system (7) along an optical axis (2) and enters the optical system (7) through a first surface (3) having both transmitting and reflecting actions. The incident light rays are reflected toward the pupil (1) by a second surface (4) which is at a side of the optical system (7) remote from the pupil (1) and which has only a reflecting action. The reflected light rays are then reflected away from the pupil (1) by the first surface (3). The reflected light rays pass through a third surface (5) having only a transmitting action, and reach an image plane (6) to form an image thereon. The first surface (3) is a rotationally symmetric surface, e.g. a spherical surface, and the second surface (4) is a rotationally asymmetric surface.

摘要： A small-sized, lightweight and inexpensive visual display apparatus which enables observation of a full-color image at a wide field angle, which is clear and flat as far as the edges thereof, without using a costly element such as a polarizing element. The visual display apparatus has an image display device (4), and an ocular optical system for projecting an image formed by the image display device (4) and for leading the projected image to an observer's eyeball. The image display device (4) has a louver (10) for limiting the viewing angle. The ocular optical system has two semitransparent surfaces (2 and 3). The second semitransparent surface (3) is a curved surface which is concave toward the observer's eyeball side, so that light rays emanating from the image display device (4) first pass through the second semitransparent curved surface (3), and are reflected by the first semitransparent surface (2). The reflected light rays are further reflected by the second semitransparent curved surface (3), and then pass through the first semitransparent surface (2) to enter the observer's eyeball. Further, the two semitransparent surfaces (2 and 3) are disposed such that at least the first semitransparent surface (2) is decentered with respect to the observer's visual axis directed to see the center of the projected image.

摘要： A display apparatus of the type that is fitted to the user's head or face, and having a higher resolution in a first region of the display than that of the remaining area of the display, without increasing the size of the display. As an example, an image of the characters "ABC", for example, are generated or received. However, it might be desired that the center character "B", for example, be displayed at a higher resolution than that of the characters "A C". To accomplish this, the original image "ABC" is divided into an image of "A C" and an image of "B". Then, the image of "B" is electrically distorted and formed on a screen such that the image of "B" is larger in size than the image of "A C". An ocular optical system including an optical element effects a second distortion of the image to correct the electrically created distortion. This ocular optical system enlarges the image such that the image of "A C", which has been displayed relatively small, is enlarged, and projects the image of "B", which has been displayed relatively large, through a lens having a correspondingly lower magnification. Then, the image of "B" is superimposed on the image of "A C" so that the image of "A C" and "B" are displayed at the same size, but with "B" being represented by more pixels or pixels which are finer than those representing "A C".

摘要： An image display apparatus designed so that the field angle for observation can be widened without causing the substrate of an image display device to interfere with the observer's head and without increasing the overall size of the apparatus. The apparatus includes a two-dimensional image display device (6), an optical path splitting device (4), and a concave ocular mirror (5). The image display device (6) is used as an object point of the concave ocular mirror (5), and the object point is projected in the air as an enlarged image for an observer (1) without effecting image formation in the optical path. In the image display apparatus, either or both the optical path splitting device (4) and the concave ocular mirror (5) are decentered so that the display center (7) of the two-dimensional image display device (6) can be shifted away from the observer's head with respect to a reference axis (8) which perpendicularly intersects the observer's visual axis (3) lying when he or she sees forward.

摘要： A portable visual display which enables observation of an image with minimal distortion includes a two-dimensional display device (7) for displaying an image for observation, and an ocular optical system (6) for projecting an image formed by the two-dimensional display device (7) or a real image thereof in the air as a magnified image and for deviating the optical axis. The ocular optical system (6) is comprised of a concave aspherical mirror. The concave mirror (6) is designed so that the curvature thereof in a direction (X direction) perpendicular to a plane (Y-Z plane) in which the optical axis conventionally increasingly deviates gradually increases in a direction (-Y direction) in which the optical axis is deviated as seen from the observer's eye (1). Alternatively, the arrangement may be such that a relay optical system for projecting a real image of the image formed by the two-dimensional image display device (7) in the air is provided, and a part or the whole of the relay optical system is disposed so that the optical axis thereof is inclined toward a direction normal to the object surface away from a straight line connecting the object center and the image center.
