Description
(実施例)
次に、具体的な実施例にて本発明の実施形態を説明する。
S(λ)=(SX(λ)−S0(λ))/(S1(λ)−S0(λ))
なお、媒体103の品質が安定している場合、S0(λ)とS1(λ)とは、一度だけ測定され、その測定されたS0(λ)とS1(λ)が次回以降用いられてもよい。この場合、S(λ)を計算するための処理を少なくすることが可能になる。
S(λ)=(SX(λ)−S0(λ))/(S1(λ)−S0(λ))
スペクトル検出部7d1は、その計算された各S(λ)を、そのS(λ)に対応する格納領域(メモリ7c)のSに格納する。スペクトル検出部7d1は、S(λ)をメモリ7cに格納すると、ステップ1605を実行する。
