本出願は、2014年1月31日に出願された米国特許仮出願第61/934,464号に対する優先権を主張するものであり、その内容は参照によりその全体が本願に組み込まれるものとする。
本開示は、概して小型の内視鏡に関係し、特にカラー撮像を行う小型内視鏡の装置、システム、製造方法および使用方法の例に関する。
それぞれの領域は、例えば10溝、50溝、100溝、500溝等の一定の溝数を有する。幾つかの例示的な実施形態では、領域の総溝数は、領域からの十分な光回折を維持するために少なくとも100になり得る。例えば、図3の3つの領域、即ち、領域310、320および330はそれぞれ溝密度を1600、2000および2400ライン/mmとすることができて、それぞれ波長675nm、540nmおよび450nmの光が組織表面の同じ位置に回折される。領域310、320および330はそれぞれ同一平面に配置され少なくとも50μm×50μm平方のサイズを有する。
