Abstract
Description
本願は、2018年11月5日に出願された米国仮出願第62/755,807号の利益を米国特許法第119条(e)に従って主張し、上記出願の全体を本明細書に引用により援用する。
X線顕微鏡検査および他の用途では、高空間分解能および高効率でのX線光子(<500keV)の検出が必要である。
しかし、シンチレータ-光学顕微鏡-カメラ検出システムにおける光学結合は完璧ではない。光学顕微鏡における有限の物体NAおよび光損失のために、集光効率が制限される。この結果、X線検出の検出量子効率(DQE)が低下し(いわゆる量子的落ち込み)、その直接的な結果として撮像スループットが低下する。
光学顕微鏡は、透過または反射において光導電検出器を読み出すことができる。
ここで、本発明の例示的な実施形態が示されている添付の図面を参照して、本発明について以下でさらに十分に説明する。しかし、本発明は、多くの異なる形態で実施されてもよく、本明細書に記載されている実施形態に限定されると解釈されるべきではない。むしろ、これらの実施形態は、本開示が完璧かつ完全であり、当業者に本発明の範囲を十分に伝えるように提供されている。
高分解能撮像および高検出効率を達成する1つの重要な局面は、検出処理におけるさまざまな要因を識別して整合させる方法である。検出処理の伝播に続いて、システム分解能に影響を及ぼす主な要因は、以下の通りである。
