Closed-Loop Autofocus Scheme for Scanning Electron Microscope

MATEC Web of Conferences, 2015
In this paper, we present a full scale autofocus approach for scanning electron microscope (SEM). The optimal focus (in-focus) position of the microscope is achieved by maximizing the image sharpness using a vision-based closed-loop control scheme.

Formation of Three-Way Scanning Electron Microscope Moiré on Micro/Nanostructures

The Scientific World Journal, 2014
Three-way scanning electron microscope (SEM) moiré was first generated using a designed three-way electron beam (EB) in an SEM. The spot-type three-way SEM moiré comes from the interference between the three-way EB and the specimen grating in which the ...

Ultra-structural Observations of Colletotrichum orbiculare on Cucumber Leaves Pre-treated with Chlorella fusca

Research in Plant Disease, 2017
Chlorella is one of the microorganisms which can live autotrophically by their own photosynthesis. It was previously revealed that pre-treatment of Chlorella fusca caused a suppression of appressorium formation on the cucumber leaves after inoculation ...
