Triads

I am familiar with the effect of a prizm on white light, turning it into the triads. I am wondering if anyone knows of a reverse method (turning the 3 individual triads into one beam of light).

sorry if this is unsatisfactory.
Dual lenses may do it, or may it not? Only if the triads are parallel, we then refract them using a (+) lense (convex?), then parallelize them back with (-) lense at the focus, now assuming the triads are of low intensity.

Triads????
Could you explain a little more please?

That is a very good idea, curioucity. Unfortunatly I do not have the equipment to test this theory in the immediate future, but I encourage anyone that reads the post with this interest to test it out and post the results. I have a wonder if this will give us deferent amplitudes of white light, or different colors (orange, yellow, etc.). And why, curioucity, do you say this must be done at low amplitudes of light? I think when a prism recieves white light, it is recieving equal amlitudes of the triads, so perhaps uneven amplitudes of the triads as an input would give us colors beyond just red, green, and blue.

Oh, and guthrie, triads are the three basic colors that humans can see: blue, red, and green. Take a magnifying glass to your comuter screen... that is all it is. Hundreds of small groups of triads. These make up every other color we see by mixing the amount of red, green, and blue in each pixel.

 

myriad,
Err.. sorry, I think I whack a point here. I apologize that even if you try hard to apply my idea, it will not work, because after you converge the triads using the (+) lense, the triads will combine into white only at the focus. The problem is, if you were to diverge the focused light right at the focus, you will need a lense with 0 focus, which is impossible. So the idea is inapplicable.
Another idea must be devised... until then, forget my first idea, sorry.

 

Well, that is ok curioucity, I think that until 0 focus you would approach white light, but until then get white light with a slight tinge of the dominate color, something of the like. The thing is I think you would need equal amplitudes of each triad. What I am trying to do is mix the colors to make more colors... not white.

In actuality, the idea came from a circuit that was a "color organ." That is, leds in the colors of the triad would light up when specific frequencies were set. I wanted to take, with this idea, an audio signal and convert it to a visual projection. The problem is, it is hard to determine the specific frequencies of sound that should determine each color. Once I determined the frequencies, I needed some way of mixing the colors, so that say a d chord could get me a yellow or orange. I am not sure when I will complete this.

Wow, pleasing project! Suddenly I have the idea if you could somehow cause a white to light when you play a musical triad using that color organ. Fun though, anyway.
