Amazingly you can create two beams of quantum linked photons, have one lightbeam meet a figurine, then the quantum linked photons outside that optical path will create an image of the figurine on a computer camera. New Scientist describes the process at the link.
Well, what if you use volumetric
light, a variety of 3d laser tweezers(link) to be only fully absorbed if it meets a 3d shape. Then when that volumetric light met the 3d shape the other quantum linked lightbeam would let the camera know it had a met the particular high quality shape.
If you aim this thing at a chemical reaction you could accurately notice the actual amount of particular microshapes when the volumetric light was optimally met.
Then you see if you can get it to work on proteins. If the 3d light shape, again similar to laser tweezers, meets up with all or most of the proteins shape then the comp[uter is able to measure the actual amount of protein at a vitro or preferably vivo sample. just have the light beam shine on a mucous membrane to measure proteins live at a living organism. If it works really well, you might be able to measure mRNA which would tell you not only what the organism was made of, you would also know what it was producing.
Medically, a laser gadget you point at a person, then it tells you their medical functionality has been described as a tricorder.
This idea is a little new with the way it creates a 3d laser tweezers, that sort of like the image on the front of Godel Escher Bach would tend to accumulate 3d shapes like very specifically shaped proteins at its central area.
When you think about it, rather than shining light from three directions on the GEB form to make perimeter images, you could shine three lasertweezers to make a GEB form field at the middle of a fluid then watch particular shaped proteins accumulate at the center. The quantum linked photons camera then notices this, which tells the software how much of what protein is around.
Also the formfield is continually reconfigurable. Is it possible pure optical PCR with a lightform is possible?
If you use lasers to microzap a tenth of a millimeter of surface tissue away, could you get a sensationless reading from any skin surface?
