Addressable projector for dot based direct time of flight depth sensing

A method comprising:

• receiving emission instructions specifying activation of one or more independently addressable channels in each subarray of a plurality of subarrays of an array of emitters, at least two of the subarrays are adjacent to each other and do not overlap;
• activating the specified one or more channels in each subarray based on the emission instructions;
• and
• illuminating a target area with a light pattern formed by tiling light emitted from the activated one or more channels in each subarray,
• the light pattern having;
• a first peripheral part that includes first dots emitted by first emitters of a first subarray in the plurality of subarrays;
• a second peripheral part that includes second dots emitted by second emitters of a second subarray in the plurality of subarrays;
• and
• a center part including a plurality of rows the first dots and the second dots, the center part disposed between the first peripheral part and the second peripheral part and having a higher illumination density than the first peripheral part and the second peripheral part.

A headset comprising:

• a first subarray of first emitters configured to emit first light;
• a second subarray of second emitters configured to emit second light, wherein the first subarray is independently addressable from the second subarray, and wherein the first subarray disposed adjacent to the second subarray;
• an optical assembly configured to generate a tiled light pattern from the first light and the second light, wherein the tiled light pattern includes:
• a first peripheral part that includes first dots of the first light emitted by the first emitters;
• a second peripheral part that includes second dots of the second light emitted by the second emitters;
• and
• a center part including a plurality of rows first dots and second dots, the center part disposed between the first peripheral part and the second peripheral part and having a higher illumination density than the first peripheral part and the second peripheral part.
