Abstract:
An optical system is provided that includes a correction portion including one or more spatially varying polarizers. A first spatially varying polarizer of the one or more spatially varying polarizers has a first control input configured to receive a first control signal indicating whether the first spatially varying polarizer is to be active or inactive. When active, the first spatially varying polarizer is operative to provide a first optical correction on light passing through the correction portion. The optical system includes a controller configured to determine whether to implement the first optical correction on the light passing through the correction portion and in response to determining to implement the first optical correction on the light passing through the correction portion, output the first control signal indicating the first spatially varying polarizer is to be active. Additional spatially varying polarizers may be controlled to provide additional or alternative optical corrections.
