Claims (2)
- 通信の相手側装置からの入射光が入射する、電圧の印加により焦点距離が可変される液晶よりなる一つの集光レンズと、
前記集光レンズを経た入射光を受光する複数の受光面を有する一つの多分割受光素子と
を備え、
前記集光レンズに対して電圧を印加することによって前記多分割受光素子における前記入射光をデフォーカス状態とし、この多分割受光素子の各受光面ごとの前記入射光の受光光量差に基づいて、前記入射光の入射方向を検出するとともに、前記集光レンズに対して電圧を印加しないことによって前記多分割受光素子における前記入射光をフォーカス状態とし、この多分割受光素子の一の受光面により、信号光の受信を行う
ことを特徴とする光無線通信装置。 - 前記多分割受光素子は、信号光検出用の1つの受光面と、入射方向検出用の4つの受光面とを、モノリシックに構成したものである
ことを特徴とする請求項1記載の光無線通信装置。
