Claims (1)
生した走査光をミラーで反射させて物品を走査し、該物
品からの反射信号光を再び前記ミラーで反射してホログ
ラムにブラッグ角で再入射する艷式のホログラムスキャ
ナにおいて、前記物品からの反射信号光の少なくとも一
部がホログラムを非ブラッグ角条件下で透過してミラー
に入射、するように構成したことを特徴とするホログラ
ム−スキャナ。The incident light for reproduction is incident on the hologram at the Bragg angle, the reproduced scanning light is reflected by a mirror to scan the article, and the reflected signal light from the article is reflected again by the mirror and re-incident on the hologram at the Bragg angle. What is claimed is: 1. A barge-type hologram scanner, characterized in that at least a portion of the reflected signal light from the article passes through the hologram under non-Bragg angle conditions and enters the mirror.
