Vinyl record grooves under electron microscope
Chris Supranowitz is a researcher at The Insitute of Optics at the University of Rochester. Along with a number of other spectacular studies (such as quantum optics, trapping of atoms, dark states and entanglement), Chris has decided to look at the grooves of a vinyl record using the institute's electron microscope...
Here is a shot of a number of record grooves (the dark bits are the top of the grooves, i.e. the uncut vinyl):
The grooves magnified 500x the little bumps are dust on the record:
And here's a single groove even closer still, magnified 1000 times:
Chris also did the pits in a CD here's what they look like, just for contrast:
Chris decided to take the whole electron microscope image one step further, and created a blue/red 3-dimensional image of the record groove! So, if you have a pair of 3D glasses (sorry, the ones you got from watching Avatar won't work you need red on the left, blue on the right), throw them on and take a look at this amazing picture:
