Abstract
A camera-movement compensation device includes a first liquid-crystal cell with a pair of parallel transparent plates and a first voltage source coupled to the first liquid-crystal cell and able to apply and alter a first voltage gradient across the plates of the first liquid-crystal cell. The device also includes a second liquid-crystal cell having a pair of parallel transparent plates and disposed so that each of the plates of the second liquid-crystal cell is parallel to the plates of the first liquid-crystal cell and in light communication with at least one wave of light passing through the plates of the first liquid-crystal cell, a second voltage source coupled to the second liquid-crystal cell and able to apply and alter a second voltage gradient across the surfaces of the second liquid-crystal cell, and a movement detector coupled to the voltage sources to alter the slope of the voltage gradients in proportion to a movement.
