Binocular vs. Stereoscopic

[P3D Dr. George A. Themelis <DrT-3d@xxxxxxxxxxxxxxxxxxxxxxxxxxx>]

I received my issue of Inside 3D today.  It looks spectacular
in its large size and with such a variety of material in it!
I have just read the first few articles.  It will take me
days to digest all the material....

One minor point.  In a review of the latest IMAX 3D film
"Four Million Houseguests" actress Chrarlotte Sullivan
is pictured looking through a microscope, identified as
a "stereo microscope".  In reality it is simply a binocular
microscope.  A binocular microscope allows both eyes to
receive the same view (non-stereoscopic) via one objective.
A stereo microscope has two objectives and presents to
the eyes two sligthtly different views, resulting in
stereoscopic viewing.  A stereo microscope usually magnifies
between 10 and 100 times.  Binocular (non-stereoscopic)
microscopes magnify from 50 to 1000 times.  The stereo pictures 
of bugs and microorganisms that we have seen are mostly taken 
with a scanning electron microscope, which offers an amazing
depth of field, by tilting the sample between the two
exposures.
