More Information
Summary:A structured light projectors includes an illuminator configured to emit illumination light, a pattern mask configured to project structured light by partially transmitting the illumination light, and a lens configured to project the structured light, wherein the pattern mask includes a first lens distortion compensation region including a plurality of opaque first light shielding patterns having a first pattern width, respectively, and a second lens distortion compensation region surrounding the first lens distortion compensation region, the second lens distortion compensation region including a plurality of opaque second light shielding patterns having a second pattern width, respectively, wherein the second pattern width is less than the first pattern width.
