Abstract

　光切替装置（１００）は、入力された光を反射させるＭＥＭＳミラーアレイ（１１７）のＭＥＭＳミラーの角度を変化させて、ＭＥＭＳミラーによって反射した光を出力する出力ポート（１１４）～（１１６）を切り替える切替制御を行う。取得部（１３０）は、出力ポート（１１４）～（１１６）から出力された出力光の強度情報を取得する。ＭＥＭＳ制御部（１４０）は、取得部（１３０）によって取得された強度情報に基づいてＭＥＭＳミラーの角度を調節し、出力光の強度制御を行う。変動検出部（１５０）は、取得部（１３０）によって取得された強度情報に基づいて出力光の所定変動量を超える変動を検出する。停止／再開部（１６０）は、変動検出部（１５０）によって所定変動量を超える変動が検出された場合に、ＭＥＭＳ制御部（１４０）による強度制御を停止させる。
