Description
This is a dataset of High-Dose-Electron (HDE) images and Low-Dose-Electron (LDE) images taken with a transmission electron microscopy used in H. Katsuno, Y. Kimura, T. Yamazaki and I Takigawa, Microsc. Microanal. 28 (2022), pp 138--144 (arXiv:2106.01718).
There are two LDE images for each HDE image.
cf) HDE image is 0001.tif and corresponding LDE images are 0002.tif and 0003.tif.
Equipment of TEM:
field-emission gun (JEM-2100F, JEOL, Tokyo)
OneView IS (Gatan, Inc., Pleasanton, CA, USA)
Typical magnification was 25,000x and 30,000x.
HDE image
The resolution was 4096 x 4096 pixels and its exposure time was 5 s.
The typical total doses was 1010 e-.
LDE image
The resolution was 512 x 512 pixels and its exposure time was 3.3 ms.
The typical total doses was 106 e-.
