Function
The dynamic technique on which 3D
microscopy is based can be used with any light
microscope with an accessible aperture
diaphragm.
The technique can be used with upright or
inverted reflected-light and transmitted-light
microscopes.
A patent has been applied for the technique.

Eyepiece version
in a reflected-light microscope
There are three different versions of 3D
microscopy:
eyepiece version
monitor version
combination of eyepiece and monitor
version
2.2.1 Eyepiece version
An LCD shutter (
"3D illumination shutter"
) is
positioned close to the aperture diaphragm and
is used to open or close one half of the beam
path.
With the eyepiece version, the LCD shutter is
controlled via the "
3D-CONTROL DSA-3"
unit.
The centroid of the illumination beam path is
switched in such a way that the object is
illuminated alternately from a right and a left
stereo angle.
The eyepiece shutters are controlled at the
same pulse rate, i.e. each eye
only sees the
image on its own side
.

A flicker-free display of the stereo image
composed of the right and left images is made
possible by an appropriately high pulse rate.
When the illuminator - eye allocation is
changed, a pseudostereo effect is created
(height-changed image).
Resolution, contrast and depth can be
optimized with relation to the object via the
aperture diaphragm.
