First CGH fringes!

Last night a package containing a new camera for the interferometer arrived so we fired that up this morning. Its larger field of view & range of gain settings made it easier to tweak the interferometer.

After Much fiddling with all the degrees of freedom for both the CGH & the interferometer, as well as adding a neutral density filter to the reference beam, we obtained our first fringes from the CGH.

With that, we proclaim the CGH test commissioned! :)
