Quick and dirty SWLI prototype

[@HuygensOptics]

Nice setup, it looks pretty stable too. The main issue with building a real wli is the software. As far as I know, there is no open source software available for this purpose.

For me you have the best video about WLI, Jerome!! Keep making videos that we keep watching!!

[@cylosgarage]

Thanks Jeroen! It looks stable until my neighbor starts walking around upstairs 😉. I made a simple piece of code last night and actually tested it with the videos of scans from your WLI video. Seems to be workable. I will try implementing it on my setup today. Need to do some calibration first.

@cylosgarage You used the images from the video? That's amazing! Let me know if you need any other specific video footage. I guess though that the most important data to reconstruct a surface is how the images relate to the position of the stage. In my case the ZYGO software takes care of everything but also completely hides it from the user.

@@cylosgarage If the vibration ends up being a big problem, you might be able to use the LED as an ultra-fast shutter by only turning it on for ~10us. That should reduce the displacement actually seen by the camera. You might need a camera with an external trigger though to sync up the pulses. I've been playing around with building a WLI with similar surplus equipment and found that trick in a paper while researching earlier today (10.1364/AO.55.006172 is the paper)

Casually building an interferometer a flex but I’m here for it.

[@chrismorrison8510]

I'd call it a skill building exercise

Thanks for sharing! Definitely would like to see a surface roughness setup!

Very cool

[@GermanMythbuster]

Great work! Love all your Videos So Inspiring ❤

[@t.josephnkansah-mahaney7961]

Very cool indeed!

WOW !!! best regards Steve

Hi Cylo, could you make the audio way louder? The information is amazing but I need to be able to receive it😅. Just to put it in scale: I listen to almost all YT videos at 20% and your videos at 100% Keep on going, Victor

[@cylosgarage]

Sorry about that, that’s just the native audio quality from my phone. For actual planned out videos I use a mic but these are just impulsive vlogs where I pick up my phone while doing something. I’m not a KZbinr I’m just some bozo with a camera and an internet connection. If this project turns into something worth a formal video, I’ll make it sound nice.

Neato !

[@arauchfuss]

I imagine that was super annoying to align! love the budget Michelson (edit) objective.

[@carltauber2939]

Your voice is very faint. The background noise is almost as loud.

[@billdoodson4232]

So I went into the workshop one weekend and knocked up an inferernometer. As you do!

[@DeathbyKillerBong]

very very cool
