Abstract
An optical deflector includes multiple voltage-dependent refractive boundaries. Light passes through the refractive boundaries and accumulates a deflection angle. An electrode placed to apply a voltage to the boundaries may be non-uniform to modulate a wavefront as it passes. A scanning laser projector includes the optical deflector to modulate laser light.
