Re: New Holograms

Hi Kris,

It's long time ago !
Nice works. Did you still use the HB-650 laser module ?

By the way, do you get some news from Hans ?

See you.

Jean

Re: polarisation mismatch

I remember a few years ago there was a thread on the holoforum how to rotate polarization of a laser using mirrors. <snip> If my memory is good enough, Kaveh placed mirrors to form a kind of periscope (this is a part of his thesis) There is a wiki page about this : http://holowiki.nss.rpi.edu/wiki/...

I'm still working with PLA but in a pair of weeks, I'll try ABS First goals : mounts for optics, chassis ...
