ユビキクス環境のための光レゾルバの開発

摘要

本研究では高速，かつ安価で場所を選ぶことなく使用可能な位置検出システムとして，光源の輝度に時空間変調を加えることでできる位相変調型の信号場を利用する手法を提案した.その中で今回は2つの面光源と受光素子を用いた角度検出システムの実装を行った.%In this article, we report novel measurement method designed by a couple of plane light sources made by IR-LED axray and a photo interrupter. Light sources emit light by the same frequency and the different phase. And optical axis of the sources is set up as orthogonal. Then, the signal place is diffused with the space where phase is different in each position. And the signal which is received by photo interrupter is analyzed, the position is analyzed from the signal which is received by photo interrupter.
