Abstract: 本発明は、本発明の方法に用いる光学システムがマルチチャネル検出器（CCDセンサや、フォトダイオードの行配列）を含まない場合に用いることが可能である多変量校正に関する。 マルチチャネル検出器のない光学システムは、前処理工程を行うことが可能でない。 よって、前述の前処理工程を別のやり方で行う必要がある。 光信号の測定によって前処理工程を部分的に置き換えることを提案している。 ここで、測定は、光学素子による光信号の透過又は反射を含み、それによって、スペクトル重み付け関数によって光信号を重み付けする。 本発明の利点は、かさばりかつ高価なCCDセンサのない前述の光学システムを用いて、多変量校正工程及び前処理工程を行うことが可能な方法を教示することである。
