Spatially-resolved dynamic dimming for augmented reality device

A method of operating an optical system, the method comprising:

• receiving, at the optical system, light associated with a world object;
• generating a desired pixelated mask at a depth from the optical system;
• deconvolving the desired pixelated mask using a power spectral density (PSF) of a pixel of a dimmer of the optical system to obtain a deconvolved pixelated mask;
• and
• adjusting the dimmer based on the deconvolved pixelated mask to reduce an intensity of the light associated with the world object in accordance with the deconvolved pixelated mask.

A non-transitory computer-readable medium comprising instructions that, when executed by a processor, cause the processor to perform operations comprising:

• generating a desired pixelated mask at a depth from an optical system, wherein the optical system is configured to receive light associated with a world object;
• deconvolving the desired pixelated mask using a power spectral density (PSF) of a pixel of a dimmer of the optical system to obtain a deconvolved pixelated mask;
• and
• adjusting the dimmer based on the deconvolved pixelated mask to reduce an intensity of the light associated with the world object in accordance with the deconvolved pixelated mask.

An optical system comprising:

• a dimmer configured to dim light associated with a world object, the dimmer comprising a plurality of pixels;
• and
• a processor communicatively coupled to the dimmer, wherein the processor is configured to perform operations comprising:
• generating a desired pixelated mask at a depth from the optical system;
• deconvolving the desired pixelated mask using a power spectral density (PSF) of a pixel of the dimmer to obtain a deconvolved pixelated mask;
• and
• adjusting the dimmer based on the deconvolved pixelated mask to reduce an intensity of the light associated with the world object in accordance with the deconvolved pixelated mask.
