Abstract: PURPOSE: To decrease the dependency on the visual angle while maintaining resolution, luminance and contrast by forming a diffusing layer consisting of transparent beads and a light-absorbing member on the front side of a liquid crystal panel. CONSTITUTION: Two polarizing films 4a, 4b which hold a liquid crystal panel 3 are arranged in such a manner that the polarizing axis of the first polarizing film 4a in the front side of the liquid crystal panel 3 and the polarizing axis of the second polarizing film 4b in the back side of the panel 3 are perpendicular to each other. A diffusing layer 7 is formed in the front side over the first polarizing film 4a and has such a structure that transparent beads 11 are densely deposited to form one layer and the space in the front face of the bead layer is filled with a light-absorbing material 12. By forming the diffusing layer 7 comprising transparent beads 11 and light-absorbing material 12 in the front side of the liquid crystal panel 3, the light emitted from the liquid crystal panel 3 is diffused by the transparent beads 11 so that a good image for a wide visual angle can be given to the observer.

Abstract: PURPOSE:To improve an image forming performance with reference to a light beam outside an axis and to obtain the accomplishment of high resolution all over a viewing angle by transforming the angular magnification of a light deflection angle by an acoustooptical deflector by use of an axially symmetric lens. CONSTITUTION:A cylindrical lens CL26 is arranged in the front stage of the acoustooptical deflector 25 for deflecting in a horizontal direction, and the axially symmetric lens L1, a cylindrical lens CL28 and the axially symmetric lens L2 are arranged in the rear stage of the deflector 25, and the angular magnification transformation for the light deflection angle by the deflector 25 is performed by the axially symmetric lenses L1 and L2. Then, the image forming performance with reference to the light beam outside the axis can be also improved and the image having high resolution all over the viewing angle can be displayed. That means, in terms of the manufacture, it is facilitated to make the axially symmetric lenses L1 and L2 aspherical and achromatic, so that, the axially symmetric lens systems L1 and L2 having little aberration as a lens system for transforming the angular magnification, that means, having the high image forming performance can be outputted. Thus, the high resolution with reference to horizontal scanning can be secured.

Abstract: PURPOSE:To obtain the plotter with few noise and superior durability and small and of light weight and to plot an image with high picture quality at high speed by performing the horizontal scan of a laser beam alternately with a pair of acousto-optical deflecting device. CONSTITUTION:The laser beam l0 is supplied to a cylindrical lens 11a, and after the beam width of the beam is magnified, it is supplied to a cylindrical lens 11b, and is returned to parallel rays, and is formed in flat shape in which the cross-sectional shape of the laser beam is magnified only in a horizontal scanning direction. A flat laser beam is supplied to a beam switch 12. The beam switch 12 is the acousto-optical deflecting device, and switches the emitting direction of an incident flat laser beam in the up-and-down direction. At such a case, since the deflection of the laser beam in the up-and-down direction with the beam switch 12 is not related to the resolution of a projecting image, it is not required to magnify beam size in a polarizing direction. By performing the horizontal scan alternately with intensity-modulated and divided laser beams, the plotter with few noise and superior durability and small and of light weight is obtained.

Abstract: PURPOSE:To contrive the decrease, etc., of a rotating speed of a rotary polygon mirror by allowing a focusing light beam to be made incident on the rotary polygon mirror so that it is not shielded by a fixed plane mirror, reflecting repeatedly this focusing light beam between the rotary polygon mirror and the fixed plane mirror, and enlarging a deflection angle made by the rotary polygon mirror. CONSTITUTION:A fixed plane mirror 20 is placed so as to be opposed to a specular surface part 11 of a rotary polygon mirror 10, and a focusing light beam l1 is made incident on the rotary polygon mirror 10 at a prescribed elevation angle phi against a virtual plane being orthogonal to a rotation axis (m) of the rotary polygon mirror 10 so that it is not shielded by this fixed plane mirror 20. This focusing light beam l1 is reflected repeatedly between the rotary polygon mirror 10 and the fixed plane mirror 20 so as to enlarge a deflection angle made by the rotary polygon mirror 10. In such a way, by a simple constitution for only placing the fixed plane mirror in a prescribed position, the deflection angle can be enlarged satisfactorily, and the decrease, etc., of a rotating speed of the rotary polygon mirror can be contrived.

Abstract: PROBLEM TO BE SOLVED: To find a lesion part at an eyeground at an early stage and accurately.SOLUTION: By irradiating an eyeground with a short-pulse laser beam for exciting a fluorescent dye for which the life of fluorescence is changed by being bonded to amyloid β protein as a target, setting the time point of emission of the laser beam as a reference, measuring light emission intensities at two different times t1 and t2 which are predetermined periods of time after the reference, and generating a fluorescence image of the fluorescent dye bonded to the target on the basis of the ratio of fluorescence intensities at the times t1 and t2, the fluorescence image projecting only the fluorescent dye bonded to the amyloid β protein contained in wastes in a yellow spot is generated. Thus, the presence/absence of drusen is found at an early stage and accurately.

Abstract: PROBLEM TO BE SOLVED: To provide an optical delay device capable of enhancing measuring precision. SOLUTION: Linear polarized probe light transmitted through (or reflected from) a polarizer is subjected to circular polarization by a 1/4 wavelength plate and returned to the 1/4 wavelength plate by a mirror to be converted to linear polarized light, which crosses the linear polarized probe light incident from the polarizer at a right angle, to be reflected from (or transmitted through) the polarizer. Accordingly, when the light path length of the probe light is displaced by the light path length displacing part arranged between the polarizer and the 1/4 wavelength plate, the displacement twice the forward path from the polarizer to the mirror and the return path from the mirror to the polarizer can be applied to the light path length of the probe light, so that the arriving time of the probe light can be delayed much more as compared with a case that the light path length of one-way probe light is displaced.

Abstract: PROBLEM TO BE SOLVED: To stably radiate electromagnetic waves having a wavelength of 400 nm or shorter with stable luminance for a long time. SOLUTION: This element is provided with an ultraviolet emission film 4 formed from a nitride of a group 3B element, and a pair of conductive films 3, 5 formed on both the surface of the ultraviolet emission film 4 in a form interposing it. The ultraviolet emission film 4 radiates an electromagnetic wave having a wavelength 400 nm or shorter by applying electric field to the pair of conductive films 3, 5. Since the nitride of a group 3B element used for the ultraviolet emission film as a base material is a chemically stable compound, the element is not deteriorated by the moisture or carbon dioxide in the atmosphere, even under a strong electric field or exposure to an ultraviolet-ray and can hence maintain stable luminance over a long time.
