摘要： An illumination optical system, an illumination unit, and an image projection apparatus employing the same are provided. The illumination optical system includes a light source irradiating a diverging light, a reflection optical system condensing the diverging light from the light source, and a lens optical system projecting the light condensed by the reflection optical system. The reflection optical system is comprised of an aspherical concave mirror. The lens optical system comprises a condensing lens having a positive refractive power in a central part and a refractive power of the condensing lens being decreased toward a circumferential part. Optical efficiency may be improved even when a light-emitting surface of the light source is relatively large and the light source cannot be regarded as a point light source.

摘要： An image display apparatus, for example, a head-mounted image display apparatus, which has a compact magnifying optical system designed so that the horizontal angle of view is as wide as 30.degree. or more, and yet the most off-axis distortion can be reduced to about 5%. The image display apparatus has a display device (D), an optical system (L+R) for projecting the content of information displayed by the display device (D) on an observer's eyeball as a enlarged virtual image without effecting image formation in the optical path, and an optical axis bending device (P) for bending the optical axis of the optical system. The optical axis bending device (P) is a beam splitter prism having a semitransparent surface. The beam splitter prism has an aspherical surface (r.sub.11) constituting a surface thereof which faces the display device (D). The aspherical surface (r.sub.11) is shaped so that the power thereof changes from a relatively positive value to a relatively negative value as the distance from the optical axis of the prism increases toward the periphery thereof.

摘要： A projection optical system and a projection display device employing the projection optical system are provided. The projection optical system includes a display device displaying an image to be projected onto an image display region, and first and second optical systems sequentially disposed along an optical path from a screen to the display device. When the optical axis of the first optical system is taken as a reference axis, the image display region of the display device is disposed with parallel eccentricity to the reference axis, and the second optical system is disposed eccentrically to the reference axis. Thus, an image displayed on the image display region is enlarged and projected on a position that is eccentric with reference to the reference axis. The projection display device includes an illuminating unit radiating light for forming an image to be projected and the projection optical system,

摘要： An image display apparatus, e.g., a head-mounted display apparatus, which uses a half-mirror or a beam splitter prism and yet has an even more compact structure and provides a favorably flat image surface. A half-mirror (S) is obliquely disposed in front of an observer's eyeball (1), and an image display device (3), e.g., a liquid crystal display device, and a magnifying reflecting mirror (4) are disposed to face each other across the half-mirror (S) and to extend parallel to the observer's line of sight. To widen the field angle without increasing the size and weight of the optical system considerably, at least one surface (L) having positive refractive power is interposed between the eyeball (1) and the half-mirror (S). An even more compact arrangement is obtained by using a beam splitter prism in place of the half-mirror (S).

摘要： A head-mounted display apparatus wherein an image displayed on an image display device is projected on an observer's eyeball, which is designed so that the displayed image can be observed at a desired angle of view and at a desired magnification by making the projection magnification changeable. The head-mounted image display apparatus includes an image display device (11) for displaying an image, and a projection optical system for projecting the image displayed on the image display device (11) onto an observer's eyeball. The projection optical system is composed of a first relay optical system (12), a second relay optical system (13), and an ocular optical system (14). The second relay optical system (13), which is an afocal optical system, is rotatable about an axis (16) perpendicular to the optical axis so that the projection magnification is changed in three steps by the rotation of the second relay optical system (13).
