  Electro-optic properties of dynamic scattering in homeotropically aligned
pure and dichroic dye-doped nematic liquid crystal samples are examined. The
optical properties of the two systems are quantified using transmission
properties of scattered and unscattered as a function of amplitude and
frequency of an applied voltage. Auto-correlation of the scattered signal at
different applied voltages is used to compare the decay times in the two
systems. Lastly, the histogram of the scattered signal reveals a wavevector
dependent large light scattering event. The dye-doped system shows a
significant enhancement of light blocking property in both normal and off-axis
light propagation. The characteristics of the system are compared to other
scattering technologies. The results suggest that dye-doped system can overcome
shortcomings in scattering based devices used for near-eye applications.
