Abstract:
The disclosed system may include (1) a light source, (2) a first diffractive optical element (DOE), optically coupled with the light source, that produces a first diffracted light pattern, (3) at least one additional DOE, optically coupled with the light source in series with the first DOE, that produces at least one additional diffracted light pattern, (4) an actuator that moves, in response to a first actuator control signal, the first DOE in a first plane perpendicular to an optical axis of the system, and (5) a lens, optically coupled with the first DOE and the at least one additional DOE, that projects structured light onto a local area based on the first diffracted light pattern and the at least one additional diffracted light pattern. Various other systems and methods are also disclosed.
