Dimming device angular uniformity correction

An optical system comprising:

• a segmented dimmer including a plurality of pixels, the segmented dimmer exhibiting viewing angle transmittance variations for application of a same voltage to all pixels of the segmented dimmer;
• a voltage controller in electrical communication with the segmented dimmer and configured to provide a set of voltages to pixels of the segmented dimmer to control transmittance levels for light passing through the pixels of the segmented dimmer;
• one or more processors programmed with instructions that, when executed, cause the one or more processors to perform operations including:
• identifying a set of angle dependent transmittance levels for light passing through pixels of the segmented dimmer;
• determining a set of voltages to apply to pixels of the segmented dimmer, wherein determining the set of voltages includes using the set of angle dependent transmittance levels;
• and
• controlling the voltage controller to apply the set of voltages to the pixels of the segmented dimmer of the optical system.
