Abstract
An optical architecture comprises a refractive cylinder that is movable relative to the incident light. By moving the refractive cylinder, the output light from the refractive cylinder is capable of sweeping through a spatial angle. Examples of the optical architecture can be implemented in an imaging system, such as a display system, for sequentially illuminating the target, such as a light valve in a display system with a high brightness.
