1. A device designed to impart a varying optical delay into an optical system based on rotation, the device comprising:
a first surface configured to be aligned substantially perpendicular to a light beam in use, the first surface having a first surface center; and
a second surface angularly offset with the first surface by an angle, φ, the second surface having a second surface center concentric with the first surface center and defining a center of the device,
wherein the device is configured to accept a light beam outside the center of the device, and is configured to rotate in a rotation angle, Θ, about the center in 360 degrees to create a continuously varying optical delay in a light beam where the continuous optical delay is defined by the rotation angle Θ and angular offset φ.
