This abstract first appeared for US patent application 18745983 titled 'CAMERA MODULES WITH MICRO-SCALE OPTICALLY ABSORPTIVE GRATINGS
Original Abstract Submitted
Embodiments described herein relate to camera modules that incorporate an optically absorptive grating that is positioned and designed to reduce the impact of stray light on images captured by the camera modules. Specifically, the optically absorptive grating is configured to absorb light that is incident on the optically absorptive grating. The optically absorptive grating includes an array of protrusions, and in some instances may be part of a grating assembly that is coupled to an optical component.
