Abstract
A tracking system generates a structured light pattern in a local area. The system includes an array of lasers that generate light. The array of lasers includes a plurality of lasers and an optical element. The plurality of lasers are grouped into at least two subsets of lasers, and each of the at least two subsets of lasers is independently switchable. The optical element includes a plurality of cells that are each aligned with a respective subset of the array of lasers. Each cell receives light from a corresponding laser of the array of lasers, and each cell individually applies a modulation to the received light passing through the cell to form a corresponding portion of the structured light pattern that is projected onto a local area.
