So could this type of interferometer be used to detect mode hopping?
I think I'll give the Michelson a go, but I need to think of a better way to mount and position mirrors, it can be quite a pain...

Fizeau Interferometry
Hello, I'm trying to get an idea of how big of an issue vibration will be. I often hear about people using Michelson interferometers for this. I don't have a beam splitter cube or a half silvered mirror yet, so I was wondering if anybody has used Fizeau interferometry to gauge the amount of vibratio...

Re: LED flashlights
Just a warning about those cheap Chinese 18650 batteries and chargers. 18650 batteries can have quite low internal resistance (as some are designed for high current draw) and can vent or blow up if either the battery or charger are defective. It might be unlikely but still worth being cautious.

Re: What's the consensus on optical tables?
Thanks for the replies, lots of great info. Named after the greek god, by the way :) I would love to visit a hologram exhibition! I have never actually seen a proper hologram in real life. After reading your post, I looked at the back of my credit card... It is a hologram, but with no parallax! How ...

Re: What's the consensus on optical tables?
even a shaky old card table will work because stability is only needed between the object and the recording plate Does the laser itself require the same level of vibration dampening? How critical is keeping the laser head motionless? I was also wondering if it's possible to use two different lasers...

Re: holographyforum IRC channel?
Original poster here, I created a new account. I think you have a good point about the forum having history, but things like Facebook have already come along and people seem to prefer to congregate there. The history is still here if it's needed. I don't particularly like Facebook, nor do I think it...

What's the consensus on optical tables?
Being new to holography, I've read through these forums quite a bit looking for a somewhat affordable optical table solution. I would much rather spend that money on a better laser if I can get away with it! I don't mind putting in some work if it means better bang for my buck, as long as I'm not sh...
