Development of a parallel detection and processing system using a multidetector array for wave field restoration in scanning transmission electron microscopy

Rev Sci Instrum. 2007 Aug;78(8):083705. doi: 10.1063/1.2778622.

Abstract

A parallel image detection and image processing system for scanning transmission electron microscopy was developed using a multidetector array consisting of a multianode photomultiplier tube arranged in an 8 x 8 square array. The system enables the taking of 64 images simultaneously from different scattered directions with a scanning time of 2.6 s. Using the 64 images, phase and amplitude contrast images of gold particles on an amorphous carbon thin film could be separately reconstructed by applying respective 8 shaped bandpass Fourier filters for each image and multiplying the phase and amplitude reconstructing factors.
