ている。The former is divided into two types: those that use glossy shutter glasses or colored or polarized lenses to separate the left and right images, and those that utilize the imaging effect of lenses such as lenticular lenses. In any case, the former method has two screens.
Because it is dimensional, it has the disadvantage that the stereoscopic image does not move continuously as the viewing angle changes. The latter holography method not only limits the viewing angle at which a three-dimensional effect can be obtained, but also requires several hours to create an image, so it has the disadvantage that it cannot dynamically display the processing results of an autopsy or the like.

に直交するＸ方向、Ｙ方向および２方向に沿って等間隔
に配列される。FIG. 1 is a perspective view showing the entire three-dimensional display device, which in this example is composed of a total of 27 light guide members In. Each light guide section 10 has a light-giving function and is made of, for example, an optical fiber having the same refractive index in the radial direction. The output ends of each optical fiber 10 are arranged at equal intervals along the X direction, the Y direction, and two directions orthogonal to each other.

。That is, each point Y in the Y direction, Y2. In each of the X-Z planes in Y, the output ends of nine optical fibers are arranged in a matrix at regular intervals in the X and Z directions. On the other hand, the input ends of each optical fiber 10 are arranged within a two-dimensional plane, in other words, within the same plane.
各光ファイバ１０の出力端は第２図に示すように凸面と

°にすることができる。The output end of each optical fiber 10 has a convex surface as shown in FIG. 2, and the convex surface serves as a light diffusing surface 21. Therefore, the viewing angle due to light diffusion is approximately 180
° Can be.

はできない。Assuming that each optical fiber 10 is arranged in the air, the third
As shown in the figure, due to the difference between the refractive index of the optical fiber and the refractive index of air, the optical fiber itself acts as a cylindrical lens that is perpendicular to the axis and has an extremely short focus. As a result,
It becomes impossible to accurately see the display position inside the three-dimensional cube. In other words, when viewed from a direction perpendicular to the y-z plane, the Y-Z plane 1ni at point x;
Nine of the display positions can be correctly displayed, but the display position of the pond cannot be viewed correctly due to the above-mentioned lens effect.
そこで、第４図に示すように、各光ファイバ１０が配列

視認可能となる。Therefore, as shown in FIG. 4, the space in which each optical fiber 10 is arranged is filled with a substance 41. That is, if the refractive index of the optical fiber 10 is nl, then the refractive index n2 of the substance 41 has a relationship of nl>n2, and is set to have a value as close to nl as possible. For this reason, the refraction effect of the optical fiber itself becomes gentle, and the actual display position and the virtual display position become closer and can be visually recognized as the actual display position.

る。The material filling the space in which each optical fiber 10 is arranged may be a liquid or a cured resin such as acrylic or epoxy resin, but it is preferable to use a cured resin since it also plays the role of supporting the optical fibers. desirable. Further, by providing the light diffusion surface 21 of each optical fiber 1 () with a wavelength filter function, a color image can also be displayed.
