Description
[送受光プローブシステムの構成]
図1は、実施形態の送受光プローブシステム1の模式図である。図1に示されるように、送受光プローブシステム1は、光出力装置100と、送受光プローブ10と、制御装置200と、デリバリ光ファイバ20と、結合部30と、入力部220と、受光部250と、を備えている。
図2は、送受光プローブ10の断面と結合部30の側面とを示す図である。上述したように、送受光プローブ10は、伝送部12と、漏洩部11と、を有している。本実施形態では、一例として、伝送部12は、ダブルクラッドファイバとして構成されている。すなわち、伝送部12は、軸方向に延びたコア10dと、コア10dを取り囲み軸方向に延びた第一クラッド10eと、第一クラッドを取り囲み軸方向に延びた第二クラッド10fと、を有している。第一クラッド10eの屈折率は、コア10dの屈折率よりも低く、かつ第二クラッド10fの屈折率は、第一クラッド10eの屈折率よりも低い。
図4は、結合部30および送受光プローブ10の一部の断面図である。結合部30は、融着あるいは接着等されることにより送受光プローブ10と接続されている。すなわち、結合部30は、送受光プローブ10と光学的および機械的に接続されている。なお、他の部材(不図示)により、結合部30の端面と送受光プローブの端面とが接するように構成されてもよい。
図5は、送受光プローブシステム1の、ブロック図である。図5に示されるように、送受光プローブシステム1は、制御装置200、入力部220、出力部230、および受光部250を備えている。入力部220および出力部230は、ユーザやオペレータに対するユーザインタフェースを構築している。入力部220は、例えば、リモートコントローラや、スイッチボックス、ジョイスティックのような操作ユニット、キーボード、タッチパネル、マウス、スイッチ、操作ボタンのような、入力デバイスである。出力部230は、例えば、ディスプレイや、プリンタ、ランプ、スピーカ等であって、画像や、印刷、音声による出力デバイスである。
図6および図7は、それぞれ、漏洩部11の構成の一例を示す断面図である。漏洩部11の第一クラッド10eの内部には、図6の例では、粒子11bが含まれており、図7の例では、空孔11cが含まれている。粒子11bや空孔11cは、例えば、直径100[nm]以下のような、ナノ構造であってもよい。粒子11bは、例えば、微粒子や、微少チューブのようなフィラーであってもよい。これらの場合、粒子11bや空孔11cによって第一光の進行方向が変化する、すなわち第一光が散乱されるため、第一光が外周面10cから径方向外側へ漏れやすくなる。
図11は、コア10dの端部10bに、図3に示された傾斜面10b1と同様の傾斜面15aを有した光学要素15Aが、融着や接着等により取り付けられている。この場合、光学要素15Aの屈折率は、コア10dの屈折率と略同じかあるいはより高く設定される。このような構成によっても、図2,3の構成と同様の効果が得られる。また、図11の構成によれば、送受光プローブ10のコア10dに、適宜な領域を照らす光学要素15Aを後付けできるという利点が得られる。傾斜面15aは、光学要素の一例である。
図15は、変形例の光出力装置100Aの一部を示している。図15の例では、デリバリ光ファイバ21の途中にカプラ23が設けられており、光源ユニット111(110)が、デリバリ光ファイバ22、カプラ23、およびデリバリ光ファイバ21を介して、コア10dと光学的に接続されている。この場合、光源ユニット111から出力されコア10dを伝送された光(第三光)を、端部10bから出力することができる。
図16は、変形例の送受光プローブ10Aの漏洩部11の断面図である。図16に示されるように、送受光プローブ10Aは、複数の並列に配置されたコア10dと、複数のコア10dを取り囲んだ第一クラッド10eと、を有した、マルチコア光ファイバとして構成されている。この場合、例えば、コア10dの数を増やすことができるとともに、コア10dをより照射範囲Aに近づけて配置することができるため、受光部250における第二光の受光強度を増大することができ、ひいては検出部214における第二光の検出感度をより高めることができる。なお、コア10dの数は、2以上であればよく、7には限定されない。
