Description
(i)たとえばLEDを用いて、赤外(IR)放射線を、赤外領域において透明である基板中に1つ以上の端部/端面から注入すること;
(ii)全反射の光学的効果(放射線が基板を「出る」ことがない)によって前記基板内に赤外放射線が伝播すること(次に基板は導波路として機能する);
(iii)基板表面をある種の物体(たとえば指またはスタイラス)に接触させて、あらゆる方向に放射線が散乱することによって局所摂動を生じさせ、偏向した光線の一部が基板から「出る」ことが可能になること
を含む。
(iv)基板端部において得られるIR放射線を検出器により分析するステップ;および
(v)検出した放射線から、表面と接触する物体の位置をアルゴリズムによって計算するステップ
の2つのさらなるステップを含む。この技術は特に、文献米国特許出願公開第2013/021300A1号明細書に記載されている。
