    • PURPOSE:To mass-produce holograms with high precision by utilizing the curing properties by electron beam for forming of a resin to be used for recording an interference fringe, and, by matching the releasing effect through an irradiation of an electron beam in two stages. CONSTITUTION:In a nitrogen chamber, an electron beam 26 is made to irradiate onto a sheet 20a of a base material on which a resin 23 having the curing properties by an electron beam is coated, then only a skin layer 27 of the resin layer 23 is cured. The sheet 20a is then introduced into a succeeding nitrogen chamber. Here, fine unevenness 31 constituting holographic information is pressed against the layer 23 of thermosetting resin by an original plate 30 of hologram, thereby the corresponding holographic information is recorded on the resin layer 23 or on its cured material layer 27 as the fine unevenness 32. On the other hand, the electron beam 26 is made to irradiate onto the resin layer 23 by passing through a sheet 20, then whole of the resin layer 23 is cured.
    • 目的:通过利用电子束的固化特性,通过用于形成用于记录干涉条纹的树脂的固化特性,以及通过两次对电子束的照射来匹配释放效果,大量生产全息图。 构成:在氮气室中,使电子束26照射到通过电子束涂布具有固化特性的树脂23的基材的片材20a上,仅照射到树脂层23的表皮层27 被治愈 然后将片材20a引入随后的氮气室中。 这里,构成全息信息的细小凹凸31由全息图原版30压在热固性树脂层23上,相应的全息信息作为微细凹凸32记录在树脂层23或其固化材料层27上。 另一方面,电子束26通过片材20照射到树脂层23上,然后使整个树脂层23固化。
