Description
本明細書では、以下の用語は、以下の意味を有する。
臨界角測定に基づく、従来技術による数多くの屈折率センサでは、光源と光検出器アレイとが、プリズムを形成している材料、例えば透明なエポキシ樹脂内に封入されている。従来技術による屈折率センサの一欠点は、こうしたセンサは通常、屈折率の測定に用いる1つの波長光を供給する光源を1つだけ用いているという点である。これには、いくつかの不利益がある。第1に、単一の光源によって入射角範囲が制限されることになり、したがって測定できる屈折率範囲が制限されることになる。第2に、単一の光源によって、センサの分解能が制限されるおそれがある。
本発明の一実施形態によれば、新しい設計の光センサ装置は、精密に機械加工された単一体の光学的に透明な材料で作製された光導波路構造体を使用し、この構造体は、測定境界面と、光源および光検出器アレイとの境界面と、を同時に形成する。
