As I know, a linear polarizer is a transparent optical instrument (like a piece of glass) that has a polarizing axis. Electric field components of electromagnetic waves that are parallel to polarizing axis of the polarizer pass through it and those electric field components that are perpendicular to polarizing axis are absorbed by the polarizer. Hence, the polarizing axis is fixed in a polarizer and when we rotate it, the polarizing axis is also be rotated and if the incoming light was polarized, we see that the surface of polarizer gradually becomes dark and then light as we rotate it.
My question here is that, is there any polarizer that for changing it's polarizing axis, we don't have to rotate the polarizer itself, it means that the polarizer be placed fixed somewhere and we can change it's polarizing axis by using for example a handle. If it hasn't made any polarizer like this I described, basically is it possible to make such a polarizer or not?
