Anyway, i found a list of extremely dangerous and pretty safe chemicals that have a high kerr constant. Might i suggest Anethole, a sweetener?

I have a great interest in vintage television on how things work .....its something i have never really tried it might go on my to do list but i would never try it with that nasty chemical i am not that Brave .
The Kerr cell i sort of feel is a pinched idea slight change of the Faraday device .
If i find information of use i like to post it up the forum is a good diary for stuff to retrieve later ..... as to wanting to make one for sure but i wouldn't have any use for it at the moment as i am working on camera ideas but it would be a nice thing to try for a future projection monitor ..time time time arrrr
Yes that's a good list i will have a look at it depends on what you can track down Anethole would be one to track down ,the first Kerr cell just used glass i think you were having a go at one any luck on the design ? Anethole is found in essential oils plant oils so that would be a easy one depends on how pure it has to be or it matters for a test at least .

I don't think this would work with a bare mirror screw. Remember, when viewing, it doesn't create any real image (that could be reversed in principle by a camera) at all.... instead, just a series of virtual images depending on where the viewer stands.
OH it would need a shutter perhaps that's a good reason i have never read about a mirror screw camera !
However, if you modified a mirror screw to give a projected image on a screen, using a lens say, then I guess you could use it in reverse as a camera.
Size is a problem as in its silly to use a large monitor mirror screw for use when a small one would be better for a camera ....just some thing i was wondering about and if it crossed your mind .
My opinions could be wrong. I may have made a mirror screw but I still don't really understand the optics in sufficient depth! Karen is much better in this regard.
Don't worry i am the same on the optics side all trial and error with me , reason i pushing my self on camera ideas its some thing i have to learn .
Yes they could of done with Karen back in the early days would of given Baird and the others a run for their money .

I have come across this video before its a great idea but it was beyond my lab skills anyway ,i had thought of LCDs before ,i am not sure they could handle the high amount of light a faraday or kerr device could may be if you put a few in parallel then i bet they could .
