"Anaglyphs On The Squad Car"
-
Perhaps the red and blue rotating lights on police cars is a form
of three dimensional video mapping of the immediate area by
videoing both the red lit surface area and the blue lit surface
area and then plugging those angles in offset somewhat at an
angle from each other to do stereoscopic vision (depth perception)
by making a video and wireframe image map that is viewable using
red and blue lense anaglyph glasses like those used in 3D comic
books and 3D movies in theaters. However those lights can be seen
from a very far distance because they use active sensing, and
perhaps a more gentle and inconspicuous approach to doing a
similar form of mapping would be to beam infrared lights
and ultraviolet lights, which in postprocessing could be converted
into the visible range of the red and blue spectrums which would
then be visible in 3D stereoscopic vision using anaglyph glasses.
