Description
(但し、Lはマイクロメータで表示される境界波長、
Tはマイクロメータで表示される、画像センサ内の有用光に反応する感光素子の中心間の間隔、
Aは画像センサ側における画像センサの感光面上に走査面の画像を形成する光学系の有効な開口率、
Nは出力画像の1個の画像要素当りの画像センサにおける感光素子の数である。)
を満足するものである。
に従って、より広範なスペクトル域を利用することも可能となり、その結果、画像の品質を損なうこと無く、またエネルギー消費を増加させることなく、より大きな放射束が提供される。
の具体化により、小型感光素子を備えたいかなる入手可能な画像スキャナを利用しても前記規格を満たす隆線パターン記録システムが構成できることが確認された。同時に、作動放射束が寄生放射束より少なくとも5倍大きいという事実は、この寄生放射束が、光学系における光の散乱および寄生反射等の二次的な要因の影響に相当するレベルにおいて、画像の品質に対する影響を有することを意味している。
Claims (5)
