LCOS-SLM (Liquid Crystal on Silicon - Spatial Light Modulator) X15213シリーズは、アドレス部にCMOS技術を応用して直接液晶を電圧制御することにより、高精度と高速応答を実現した反射型電気アドレス空間光位相変調器です。最適な光学設計により、高回折効率と高光利用効率を実現しています。 コントローラ部には、インターフェースとしてPCディスプレイなどの標準規格であるDVI (Digital Video Interface)を採用しており、 PCのディスプレイに表示するのとまったく同じ方法で光の位相の空間分布を制御することが可能です。LCOS型SLMでは、ミラーの表面の歪曲・液晶層の厚さの不均一性・液晶の非線形応答性などによる制御歪が避けられませんが、X15213シリーズではデジタル処理によりこれらの影響を補正し、高精度な制御を実現しています。 このようにX15213シリーズでは、PCからの制御が容易であるだけでなく、高精度・高線形な空間光位相変調をも実現しています。

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. Cookies are used in order to make websites function and work efficiently. Cookies are uniquely assigned to each visitor and can only be read by a web server in the domain that issued the cookie to the visitor. Cookies cannot be used to run programs or deliver viruses to a visitor’s device.
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.
