Function Combined version
2.2.3 Combination
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 combined 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 shutter and the camera and
monitor shutters are controlled at the same
pulse rate, i.e. each eye only sees the image
on its own side.
right eye
left eye
In the monitor version, allocation is made via
the display of the half images in two
perpendicular polarization directions which can
be allocated to the eyes by polarizing glasses.
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.
