Abstract
A Heads-Up Stereo Display device is described for stereo microscope image presentation. Liquid crystal viewing screens are used to provide large exit pupils in the left and right channel. The observer, therefore, is presented with an eye level, three-dimensional image. The optical system is described showing how scattering is used to accomplish the pupil enlargement without mechanically moving parts, but rather by using the liquid crystal screen as an active optical diffuser.
