G12242-0707Wは、CMOS読み出し回路 (ROIC: readout integrated circuit)と裏面入射型InGaAsフォトダイオードのハイブリッド構造を採用しています。1画素は1つのInGaAsフォトダイオードと1つのROICによって構成され、バンプにより電気的に接続されています。ROICにはタイミング発生器が内蔵されており、外部からマスタークロック (MCLK)とマスタースタートパルス (MSP)を入力するだけで、アナログビデオ出力、AD-TRIG出力が得られます。 G12242-0707Wは128 × 128画素が20 μmピッチで配列され、1本のビデオラインから信号が読み出されます。入射光はInGaAsフォトダイオードで光電変換された後、Inバンプを介してROICに入力されます。ROICではチャージアンプで電圧変換され、シフトレジスタにより順次ビデオラインから出力されます。なお、G12242-0707Wはメタルパッケージで1段電子冷却型ハーメチック構造のため、安定動作を実現しています。

For modern websites to work according to visitor’s expectations, they need to collect certain basic information about visitors. To do this, a site will create small text files which are placed on visitor’s devices (computer or mobile) - these files are known as cookies when you access a website.
