AstroTerra's three dimensional display technology uses intersecting wavelength tuned lasers in a heated gaseous medijm to cause a point fluorescence which can be scanned around to create three dimensional images. These images are viewable from all sides and inherently possess the correct perspective to allow the eye to judgerelative depths. The result is a true threedimensional depicition of the information beingdisplayed that requires no interaction on the partof the user. The use of a gaseours medium frointersecting the lasers allows for easy scaling tolarge displays. Mystec Associates, NEOSTechnologies, and Corning have all committedin-kind equipment and engineering to this Phase IIeffort. The unit prototyped in Phase I was aboutone cubic foot in volume and only capable ofdisplaying the color red. Work to be performed inPhase II will include scaling the display up to a four foot diameter hemisphere, integration withexisting battle management workstations, buffergas effects, and testing of different wavelengthlasers to generate other colors.
