摘要： PURPOSE:To always maintain the shape of the surface of an elastic body at the time of deformation when the position of a focal point is changed for example, in a spherical surface or desired aspheric surface, by forming the elastic body in such a way that two or more elastic layers having specific elastic characteristics and different elastic moduli are appropriately combined and put on another. CONSTITUTION:Two or more light transmissive elastic materials 1-1 and 1-2 having different elastic moduli are put on another in the direction of the optical axis. The storage elasticity and loss elasticity of these elastic materials measured in accordance with D-4065, ASTM are respectively within a range of 5X10 -1X10 dyne/cm and the dynamic loss factor within a frequency range of 0.1-10 rad/s is 1. By moving an opening-equipped plate 4 which can deform the surface of the elastic body by protruding or sinking the elastic body and/or a bottom plate 2 along the direction of the optical axis (h), the part of the elastic body 1 corresponding to the opening 4a of the plate 4 is protruded or sunk and the curvature of the surface 1a of the elastic body is changed so as to obtain a desired focal distance.

摘要： PURPOSE:To satisfactorily perform the correction of aberration and to observe dis played information in a good state even in the case of applying on the surface of an asymmetrical glass substrate by disposing a 2nd beam deflecting member in an asymmetrical plane in a gravity direction against a plane formed of the center of a display device and the center of 1st and 2nd beam deflecting members. CONSTITUTION:The 2nd beam deflecting member 35 is disposed in the asymmetrical plane in the gravity direction against the plane formed of the center of the display device 9, the center of the 1st beam deflecting member 11 and the center of the 2nd beam deflecting member 35. For example, a luminous flux 1 having the wavelength of lambda0 from the display device 9 is made incident on the 1st beam deflecting member 11 at the angle of theta 1 and reflected and diffracted at the angle of theta 2 so as to become the luminous flux 2. The luminous flux 2 is made incident on the 2nd beam deflecting member 35 at the angle of theta 3 and reflected and diffracted at the angle of theta 4 so as to be guided to an observer 51 direction. Thus, the virtual image 49 of the displayed information displayed on the display device 9 is superposed on image information such as a scenery 101, etc., in front of the 2nd beam deflecting member 35, and then, both information is observed in a good state.

摘要： PURPOSE:To improve various performances by a long wavelength laser, such as helium neon laser, by adding a styryl dyestuff as a sensitizer to a recording medium consisting of a polyvinyl carbazole polymer and a halogen compd. CONSTITUTION:The styryl dyestuff is added as the sensitizer to the recording medium consisting of the polyvinyl carbazole (PVCz system) polymer and the halogen compd. The PVCz polymers are the polymers essentially consisting of vinyl carbazole and its alkyl substd. deriv., etc., and are previously activated by the halogen compd. for radiations. The sensitizer is the dye which is made quaternary in the nitrogen atom in the molecule by binding of the styryl group with the heterocycle. The volume phase type hologram is formed by the long wavelength laser including the helium neon laser in this way and the various performances, such as light resistance, moisture resistance, diffraction efficiency, transparency, and low haze characteristic, are improved.

摘要： PURPOSE:To make an observation without any color blurring while reducing the size of the whole device by using a nonlinear optical element which generates a high frequency in the visible-light range and a luminous flux coupling element such as a hologram. CONSTITUTION:Laser light of wavelength lambda1 from a laser 1 is scanned by an optical deflector 2 in two dimensions and made incident on the nonlinear optical element 3. The nonlinear optical element 3 converts the incident coherent light of wavelength lambda1 into luminous flux of wavelength lambda2 and thus the nonlinear optical element 3 generates the scattered light which is wavelength-converted to the wavelength lambda2, thereby displaying display information 4. Then luminous flux based upon the display information 4 generated by the nonlinear optical element 3 is incident on the hologram 5. The hologram 5 has such optical characteristics that a display body 8 in an external field and display information 4' which is converted into the scattered luminous flux of wavelength lambda2 are observed spatially one over the other. Consequently, while the whole device is reduced in size, the observation is made in a state wherein there is no color blurring and the contrast is high.

摘要： PURPOSE:To enable both picture and display information of a natural landscape or the like to be observed under the satisfactory condition by calculation using of the output signals of position of an object and speed of a movable object to drive a display element on the basis of the output signals, change and display the display position. CONSTITUTION:A calculating means 301 obtains where pictures by a display element 305 should be displayed in front of a front glass light beam combining element 202 on the basis of the output signals from a measuring means 300, height detecting means 306 and speed detecting means 303 and sends the drive signal to a drive means 304. The drive means 304 drives the display element 305 on the basis of the drive signal from said means 301. Hence, a virtual image of the display element 305 is observed at a predetermined front position of the front glass. Both display information and other picture information can thus be always observed by a driver under the satisfactory condition at a proper view position corresponding to vehicle speed by displacing the display position of display element on the basis of the angular velocity of moving landscape observed by the driver.

摘要： PURPOSE:To prevent the quantity of light from decreasing owing to a shift in observa tion position by a 1st diffraction grating which has characteristics with wider wave length width than a 2nd diffraction grating and correcting a blur due to the wavelength dispersion of a display image. CONSTITUTION:Luminous flux 32 is reflected and diffracted by the 1st diffraction grating 11 on a substrate 10 to become luminous flux 33, which is reflected and diffracted by the 2nd volume phase type diffraction grating 35 on a substrate 34 to become luminous flux 36, so that the luminous flux is observed at an observation position 51. Here, pieces of luminous flux 32' and 33' which have wavelength longer than the center wavelength are determined from the observation position 51 along the optical path 36 and the grating pitch and arrangement angle of the diffraction grating 11 and the optical path length of the pieces of luminous flux 32 and 33 are so set that the pieces of luminous flux cross each other on a display element 31. Therefore, even if the observation position shifts from a position 51 to an upper position 52 or lower position 53, the center wavelength where diffraction grating is maximum shifts to a short-wavelength or long-wavelength side because of the characteristics of the volume phase type diffraction grating 35. Consequently, the quantity of light is prevented from decreasing owing to the shift in observation position.

摘要： PURPOSE:To form fine pattern with high accuracy and high density by forming the above material of a polymer contg. a specific structural unit in the main chain structure. CONSTITUTION:This material is formed of the polymer contg. the structural unit expressed by the formula (I) in the main chain. (In the formula, X denotes O or S.) Any polymers contg. the structural unit in the main chain structure are usable in this case. Namely, the polymer in which, for example, all of the main chains consist of the structural unit, the polymer in which this structural unit and >=1 kinds of the structural units coexist in the main chain, and the polymer in which a halogen group, alkyl group, alkyl halide group, etc., are substd. in the structural unit of the main chain are equally satisfactory. The ratio of the structural unit in the main chain is preferably about >=20%. The formation of the ultrafine patterns having the high accuracy and high density is thereby enabled.
