摘要： A variant of the Foucault (knife-edge) aperture is disclosed that is designed to provide single-sideband (SSB) contrast at low spatial frequencies but retain conventional double-sideband (DSB) contrast at high spatial frequencies in transmission electron microscopy. The aperture includes a plate with an inner open area, a support extending from the plate at an edge of the open area, a half-circle feature mounted on the support and located at the center of the aperture open area. The radius of the half-circle portion of reciprocal space that is blocked by the aperture can be varied to suit the needs of electron microscopy investigation. The aperture is fabricated from conductive material which is preferably non-oxidizing, such as gold, for example.
摘要翻译：披露了福柯（刀刃）孔径的一个变体，其被设计为在低空间频率下提供单边带（SSB）对比度，但是在透射电子显微镜的高空间频率下保留常规的双边带（DSB）对比度。孔包括具有内部开口区域的板，在开口区域的边缘处从板延伸的支撑件，安装在支撑件上并位于开口开口区域的中心处的半圆形特征。被孔径阻挡的倒圆的半圆形部分的半径可以改变，以适应电子显微镜研究的需要。孔由优选非氧化性的导电材料制成，例如金，例如金。
