摘要:
The present invention relates to a multi-eye image displaying apparatus and a method using this apparatus. The apparatus comprises an image displaying element, provided for each of right and left eyes and a virtual image moving element for moving at least one of the virtual images for the right and left eyes in a horizontal direction. The image displaying element has an illuminating element for emitting light and, a display unit for displaying an image by using the light from the illuminating element. The image displaying element also has an optical system for projecting the light from the display unit toward a pupil of a viewer and, as a result, forming virtual images of the image to be displayed on the display unit in front of the pupil.

A volume phase type hologram has a diffraction lattice recorded in a poly(N-vinyl carbazole) polymer layer where the diffraction lattice is recorded throughout the thickness direction of the polymer layer. A method for preparing the volume phase type hologram has the steps of exposing a photosensitive polymer layer provided on a substrate to an interference pattern; subjecting the polymer layer having been exposed to a first development treatment with a first organic solvent; and peeling the polymer layer off the substrate and subjecting the polymer to a second development treatment with a second organic solvent preferentially from the face that had been in contact with the substrate.

A method of observing information includes the steps of converting a radiation beam into a visible harmonic beam conforming to the information and observing the information by the harmonic beam. An apparatus for observing information therethrough includes a source for producing a radiation beam conforming to the information, and a converter for converting the radiation beam into a visible harmonic beam, with the information being observed with the aid of the harmonic beam. In addition, a head-up display apparatus includes a source for producing a radiation beam conforming to information to be displayed, a converter for converting the radiation beam into a visible harmonic beam, and a beam combiner for receiving the harmonic beam and directing it in a predetermined direction to effect the display of the information by the harmonic beam.
