A way to plastically flip a circular polariser?

AI Thread Summary
The discussion focuses on finding a material or method to reversibly flip the polarization of a circular polarizer, potentially using electrical stimuli. The concept relates to photonic computing, with the possibility of using pressure, heat, or other stimuli for the flip. Liquid crystals are mentioned as a relevant technology, as they can rotate the plane of polarized light, which is the basis for LCDs. The user expresses a realization about this technology and inquires about the existence of a solid-state version. Overall, the conversation explores innovative approaches to manipulating light polarization for advanced applications.

hi, I'm currently talking about light, and I'm trying to find out if there is a material or a method that can flip a polariser's polarisation...

ie, if i apply a current, then this crystal changed from a clockwize polariser to an anti-clockwize polariser, and it is either a plastic or elastic flip

because I'm currently looking at photonic computing, and i think i saw a paper on a similar topic before... (i forgot the stimuli of the flip , so it may be pressure, heat or loads of other stuff...

thankyou

Do a search on Liquid Crystals and the Rotation of the Plane of Polarized Light. That is the technology behind LCDs (liquid crystal displays). :smile:

i face plamed myself for not able to recall this simple technology...

thanks

BTW, is there a solid version of this?
 

Thread 'Pentaprism with magnification, which surface is curved?'

I would like to use a pentaprism with some amount of magnification. The pentaprism will be used to reflect a real image at 90 degrees angle but I also want the reflected image to appear larger. The distance between the prism and the real image is about 70cm. The pentaprism has two reflecting sides (surfaces) with mirrored coating and two refracting sides. I understand that one of the four sides needs to be curved (spherical curvature) to achieve the magnification effect. But which of the...
