G9203-256DAは、光通信におけるWDMモニタ用の検出器として設計されたInGaAsリニアイメージセンサです。CMOSチャージアンプアレイ、CDS回路、オフセット補償回路、シフトレジスタ、タイミング発生器などがInGaAsフォトダイオードアレイとともに組み込まれており、近赤外波長域で高い感度と安定した動作が得られます。パッケージは気密封止されており高い信頼性を実現しています。さらに、入射窓は反射防止処理が施されているため光検出効率が向上しています。 CMOSチップ上の信号処理回路は、外部電圧によって2種類の変換効率 (CE: conversion efficiency)から選択できます。イメージ センサをCE=16 nV/e-で動作させた場合は広いダイナミックレンジが得られ、CE=320 nV/e-の場合は高いゲインが得られます。

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.

Cookies do various jobs which make the visitor’s experience of the internet much smoother and more interactive. For instance, cookies are used to remember the visitor’s preferences on sites they visit often, to remember language preference and to help navigate between pages more efficiently. Much, though not all, of the data collected is anonymous, though some of it is designed to detect browsing patterns and approximate geographical location to improve the visitor experience.
