Abstract
【解決手段】光走査型内視鏡プロセッサはスキャン駆動回路、タイミングコントローラ、受光器、およびA/Dコンバータを有する。スキャン駆動回路は光供給ファイバの出射端が等角速度で渦巻き型変位経路に沿って変位するようにファイバ駆動部を制御する。光供給ファイバの出射端から照射される白色光の観察対象領域における反射光が受光ユニットが受光する。受光ユニットにおける受光器が反射光の受光量に応じた画素信号を生成する。A/Dコントローラは画素信号をA/D変換して、デジタル信号である画素信号を生成する。タイミングコントローラは出射端と基準点との距離に対してA/D変換の周期が反比例するようにA/Dコントローラを制御する。
