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 × 9.5 μ m 2 pixels show an improvement of a factor of two in point spread function to 2.7 μ m at 300 keV and of a factor of three in the image contrast, compared to traditional bright field illumination.
