I've had the idea of utilizing Optometric methods to mix chemicals in order to receive and produce aromas and flavors through cameras and TVs.
Every chemical component has a certain visible spectre, so Optometry could help measure said spectre and, with the right combination, reproduce the aforementioned phenomena, that is, aromas and flavors.
So, a camera with Optometric equipment will detect components, and later, a TV with the same equipment can receive the measurements, mix them, and reproduce whichever aroma and flavor the camera captured.
Kinda like reproducing one color by mixing RGB values.
I've already forgot most of my practices as a "Chemical Pharmacobiologist" that I was taught at highschool to determine the purity and reproduction of certain components in medicines, products and whatnot. So this idea I've had it for more than 10 years... 2010 if I recall correctly.
So, if this is totally true, I'm interested in finding out how Japanese achieved this. Maybe they're stimulating tongue receptors?
