摘要:
A heads-up display unit provided with a display device serving as display image forming means which displays a display image. A hologram serves as a reflecting means, and reflects the display light emitted from the display device, causing reflection of the display image on the interior surface of a vehicle's windshield. A display image is formed outside the windshield towards the front of the vehicle. A concave mirror having a different focal length in different directions is recorded in the hologram serving as a reflecting means so as to offset distortion of the display image caused by curvatures of the windshield. This construction makes it possible to cause the windshield to display a display image free from distortion.

A method of producing a holographic optical element which is capable of imparting complex corrections to the holographic optical element and of effecting the exposure using a short optical path permitting little disturbance to be infiltrated. A correction holographic optical element 13 for correcting the characteristics of the holographic optical element is disposed in at least one of the optical paths of an object beam 35 and a reference beam 36 that fall on a photosensitive material 11. The object beam 35 may be one obtained by reflecting the reference beam 36 by a reflection-type holographic optical element such as a reflection-type master holographic optical element 12. In the case of a holographic optical element used for the head-up display, the correction holographic optical element 13 may be given characteristics for correcting the curvature of the windshield or characteristics for correcting color aberration.

A hologram forming system for forming holograms on multiple exposures is provided. In this system, a holographic recording medium is exposed to light beams at least twice at incident angles different between exposures. The incident angle during each exposure process is determined in a given relation to the thickness of the holographic recording medium which tends to vary as the exposure process is repeated so that the reconstruction wavelengths match with target values without shifting between image colors during reconstruction of the hologram.

A head-up display includes a projector which projects an image light and a hologram lens which diffracts and reflects the projected image and form a virtual image located ahead of a windshield. The hologram lens has a vertical diffraction characteristic which is equivalent to a hyperbolic or parabolic-curve mirror along a line formed by the intersection of the hologram lens and a vertical plane which includes an axis of the image light and a horizontal diffraction characteristic which is equivalent to a parabolic or elliptic curve mirror along a line which is formed by the intersection of the hologram lens and a horizontal plane which includes the axis of the image light. When the hologram is directly attached on a curved windshield which has a focal length fs (in case it is a mirror), the focal length fo of the hologram and the former focal length fs has the following relationship; 1/fo=1/fh+1/fs, where fh is a focal point when the hologram is flat.
摘要:
A hologram display apparatus in which chromatic aberration hardly occurs even when light of a wide bandwidth is used as a reproducing light. The apparatus has a hologram combiner 10 with a diffraction characteristic of lens, and is adapted to receive a signal light including information to be displayed and to generate, in response to the signal light, a reproduced light to be seen and acknowledged by an observer. The hologram combiner 10 has a curved surface with a constant curvature in at least one of a first direction and a second direction perpendicular to the first direction. The center 01 of curvature of the curved surface is positioned at substantially the same position of the center 02 of curvature of the lens equivalent to the hologram 11.

A manufacturing method for a hologram which can control the formation of a ghost hologram due to a surface reflected light caused on an interface with the atmosphere is disclosed. In the first manufacturing method for a hologram by a two-beam method or a one-beam method, on an interface between a substrate having a hologram photosensitive layer and the atmosphere is disposed a quarter-wave plate, and an incident light is converted from a circularly polarized light to a P-polarized light (or an S-polarized light) through the quarter-wave plate. On the other hand, in the second manufacturing method for a hologram, a substrate, which has a hologram photosensitive layer, is fittingly held by prisms on both sides thereof. A reference light is a P-polarized light, and an angle of the reference light to a surface reflected light on an interface of the reference light is set to be approximate to a right angle. It is appropriate that a reproduced hologram is manufactured by the one-beam method by using a hologram manufactured by the above method as a master hologram.

摘要:
A radar apparatus for detecting a distance to an object by receiving an electromagnetic wave reflected by the object is disclosed. The radar apparatus comprises a scan part and an electromagnetic wave emitter. The scan part includes a polarized light separation member configured to pass a preset first component of the electromagnetic wave and reflect a preset second component of the electromagnetic wave. The first and second components, respectively, are polarized lights having first and second polarization directions, which are perpendicular to each other. The scan part scans the second component of the electromagnetic wave in a predetermine scan angle range by rotating the polarized light separation member around a predetermined rotation axis. The electromagnetic wave emitter emits the electromagnetic wave toward the polarized light separation member of the scan part.
