I Question regarding using existing technologies to make 3-D laser display

  1. Jun 29, 2016 #1
    I want to start off with an IR viewing plate to get the initial material of this post across.

    This is UV backlit screen that allows IR laser point to be tracked
    The screens are a mixture of:
    Zinc Cadmium Sulfide, Silver, Nickel Doped (Yellow)
    Zinc Sulfide, Copper Chloride Doped (Green)

    ^ I cannot seem to find these online for purchase;

    My interest here is more broad and not specific to a single question, but perhaps instead more of related to the engineering of certain technologies and probably there will be some simple answers at fault of a basic lack in understanding of physics and proper science.

    My broad question is that:
    if the pigment represented in the video was made to be a sparse and contained as a static volume in some medium, then a UV laser with a line diode can beam a "slice" of glowing pigments into said volume;

    With the video in mind using something in regards to a DLP(micro mirror technology) projector for speed and clarity, could one not reflect a properly focused IR lamp as to project an inverse of the image(like as the outside of a silhouette).

    I would expect based on that video that bright spots can then be seen to represent solid volumes of an image; while the dark spots which are exposed to IR light represent area's of the volume not meant to be solid.

    Would this combination of pigments/light allow me to draw 2D "slices" which can then be made 3D by moving the proposed UV laser "screen" back and forth?

    It seems that in the video at least, surely something like this can be accomplished, however without having been able to purchase and create these different pigments to experiment against I am not sure what to expect.

    I imagine that a simple problem with this may be that the pigment will emit light with only IR lasers. Which i assume would cause the entire volume to always be "lit" up from the DLP projector described above, and the volumetric effect lost.

    Seems like an easy experiment.. but again, I don't have the chemicals or knowledge to really pull that off(or even the opportunity to try since I cannot find these chemicals!)

    Thanks for the post! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?
