Description
構成は、図1に示された構成に関して類似していた。レーザーヘッドと検出器は、既知の距離(48.1mm)を離してセットされた。引っ張りの技術、すなわちレーザーおよび検出器に近接して接触している試料の壁の使用の改良された性能を示すために、2セットの測定を行った。
構成は、図2に示された構成に関して類似している。光源レーザーヘッドと検出器ヘッドは、既知の距離(64.3mm)で離してセットされた。押しの技術、すなわち光源レーザーヘッドおよび検出器ヘッドに近接して接触している試料の壁を使用する、改良された性能を示すために、2セットの測定を行った。
測定は、パッケージの壁の至近距離ニレーザーおよび検出器を移動させることにより、およびレーザーと検出器を固定させる場合と比較して距離を検出することにより、性能の向上を示すために行われた。
