Cluster Imaging with a Direct Detection CMOS Pixel Sensor in Transmission Electron Microscopy

arXiv:0907.3809 · doi:10.1016/j.nima.2009.07.017

Abstract

A cluster imaging technique for Transmission Electron Microscopy with a direct detection CMOS pixel sensor is presented. Charge centre-of-gravity reconstruction for individual electron clusters improves the spatial resolution and thus the point spread function. Data collected with a CMOS sensor with 9.5 micron pixels show an improvement of a factor of two in point spread function to 2.7 micron at 300 keV and of a factor of three in the image contrast, compared to traditional bright field illumination.
