なかった。A hologram formed by interfering the object light with the reference light reproduces the displayed information as a three-dimensional image, so the peripheral part is not noticeable, but it is a reflective hologram that is used as a combiner for head-up displays in automobiles, aircraft, etc. The sheet has a reflectance peak at a specific wavelength, and its complementary color is transmitted and visible.In addition, in conventional reflective holograms in which the hologram is recorded on the entire surface, the optical properties of the edges and other parts are changed due to heat treatment etc. Because of the difference, the boundary between the hologram sheet and the plate glass etc. is clearly visible and conspicuous, which is not desirable from a safety standpoint.
本発明はこのような点に鑑みてなされたもので、ホログ

れるホログラムシートを提供することを目的とする。The present invention has been made in view of the above points, and an object thereof is to provide a hologram sheet that is soft and visually recognizable by forming a blur pattern unique to holograms at the boundary between the hologram sheet and a transparent plate-like body such as a plate glass. With the goal.

ラム記録部分と無記録部分を混在させ、ホログラム記録
部分は、その断面積がエツジ部に向けて次第に小さくな
るよう複数、形成するようにしたものである。The present invention is a hologram sheet provided on a transparent plate, in which a hologram is recorded on almost the entire surface of a sensitive material, leaving a peripheral area, and at least no hologram is recorded in the remaining area of the peripheral area. More specifically, the remaining portion may be entirely a hologram-free portion, or the remaining portion may include a hologram-recorded portion and a non-recorded portion, and a hologram-recorded portion may be formed. A plurality of portions are formed so that the cross-sectional area thereof gradually decreases toward the edge portion.

きく、板ガラスなどの透明板状体のそれより小さいので
ホログラムシートの周辺部分、すなわち板ガラス等の板
状体との境界部分がシャープに視認されることはなく目
立たなくなるものである。A hologram is recorded on almost the entire surface of the photosensitive material except for the peripheral area, and the remaining area of the peripheral area has a small area (no hologram recorded), so that the edge portion of the hologram is formed on the edge of the photosensitive material. This prevents the optical properties of the hologram edge portion and other portions from becoming non-uniform due to heat treatment, etc., and also prevents the transmittance of the hologram non-recorded portion, which includes a transparent plate such as a plate glass, from becoming as high as that of the transparent plate. Since it is larger than that of the hologram recording part containing the hologram sheet and smaller than that of a transparent plate-like object such as a plate glass, the peripheral part of the hologram sheet, that is, the boundary part with the plate-like object such as a plate glass, is not sharply visible and becomes inconspicuous. It is something.
さらに、残余部分にホログラム記録部分と無記録部分を
混在させ、ホログラム記録部分は断面積がエツジ部に向
けて次第に小さくなるように複数形成すると、反射主波
長の補色（透過光）も次第に薄くなるのでより好ましい
。Furthermore, by mixing hologram recording areas and non-recording areas in the remaining area, and forming multiple hologram recording areas so that the cross-sectional area gradually decreases toward the edge, the complementary color (transmitted light) of the main reflected wavelength will also gradually become lighter. Therefore, it is more preferable.
この場合に、残余部分のホログラム記録部分の回折効率
をエツジ部分にかけて次第に小さくすると、ホログラム
自身の反射主波長の補色が次第に薄（なり、ぼかし効果
が増幅される。In this case, if the diffraction efficiency of the remaining hologram recording portion is gradually reduced toward the edge portion, the complementary color to the main reflection wavelength of the hologram itself becomes gradually fainter, and the blurring effect is amplified.
以下、図面を参照しながら本発明の詳細な説明する。 Hereinafter, the present invention will be described in detail with reference to the drawings.

, and a hologram non-recorded area 1 is formed in the remaining part around the periphery.
In this example, the hologram non-recorded portion 16 and the hologram recorded portion 17' are mixed so that the area of the remaining hologram recorded portion 17'' gradually decreases toward the edge portion. In the above example, the remaining hologram recording portion 17' is formed so that its area gradually decreases toward the edge portion, and conversely, the hologram non-recording portion 16 is formed so that its cross-sectional area increases toward the edge portion. be.

This is an example in which the diffraction efficiency of the outermost hologram 17' is made to be approximately O by gradually decreasing the diffraction efficiency from (90 to 100%) toward the edge. A circular portion corresponding to the hologram recording portion 17' may be exposed by sandwiching the photosensitive material with black paint or the like of varying density so that the transmittance of the laser beam gradually decreases toward the edge portion.
