Vibrations of the soundboard of a guitar visualized
- cpenner461 15y agoThis is really neat. I just finished building an acoustic guitar, I'd love to see it's acoustic profile as compared to some others... Hmm, another project idea to investigate (although I'll prob have to settle for the old fashioned method).
- ovi256 15y agoLaser interferometry is not beyond the scope of an amateur. You just need a laser :-) A true one not a handheld pointer. Then you'd need some optics and a darkroom.
- abecedarius 15y agoWhat's wrong with a pointer? Not coherent enough? It seems like a real laser when you shine it on a CD, at least (ghetto diffraction grating).
- ovi256 15y agoYeah, coherence, altough I'm sure you can test for that. Some cheap pointers use nothing more that collimated LEDs.
