First interference

A project log for Michelson interferometer

A Michelson interferometer made (mostly) by 3d printing and repurposing components from disassembled optical drives.

For about a week I have been able to see interference fringes projected onto the wall with the Michelson. I have been able to see the linear fringe pattern due to the mirrors being angled with respect to each other as well as circular and hyperbolic fringes. It has taken a lot of hours to get to this point and I almost jumped out of my skin when I finally managed to make it work.

My immediate plan is to make my laser diode driver circuit a bit less jumpy and then I can move onto some more ambitious goals...
