A new method of
image processing of corona virus based on two and multiple beam interference is
suggested. The method is based on measuring the fringe shift with respect to
the background interference pattern. The interested application of the corona
virus image in confocal microscopy is getting depth information since it has
the property of optical sectioning. An accurate measurement of the fringe shift
is obtained using multiple beam interference since contrast is higher than that
for two beam interference. The refractive index of the corona virus image is
deduced from the fringe shift. A MATLAB code is used for the processing of all
images.
