SCRAMBLERS

 

It seems that  it is easier to linearly polarize light  than completely scramble it. Complete scrambling or depolarization means that azimuth and phase of the light beam is random at any instant. We make monochromatic as well polychromatic depolarizers from crystals of calcite, quartz and magnesium fluoride. 

Monochromatic scramblers which are designed for use with a single wavelength or a narrow spectrum of light are of single or double wedge type. The wedge shape causes a slight doubling effect and may be unsuitable for imaging systems. These must be oriented at 45 degrees to the plane of polarization of incoming light.  

Polychromatic scramblers are used to depolarize a wide bandwidth at one time. These are of single plate multi order or double plate Lyot type. A Lyot scrambler is made of two multi order retarders having thickness ratio of 2 : 1 and with fast axis of one aligned at 45 degrees to fast axis of the other.
