Abstract
Structured light projection system includes an array of light emitting devices, which is configured to emit a pattern of light. A projection lens is configured to receive and project the pattern of light from the array to a first optical element. The first optical element alters the pattern of light to generate a first emitted pattern of light that is irregular. The first emitted pattern of light is transmitted to a second optical element that is configured to receive the first pattern of light and reproduce the first emitted pattern along a second emitted pattern, which comprises multiple instances of the first emitted pattern arranged in a tiled pattern.
