Abstract: A passive speckle-suppressing diffuser includes a microlens array for diffusing a light field originating from one or more coherent light beams, and a diffractive optical element mounted in series with the microlens array and having a pixelated thickness distribution, characterized by a spatial variation across the diffractive optical element, to impose a spatially varying phase shift on the light field. The pixelated thickness distribution may be configured such that the spatially varying phase shift suppresses speckle of the light field while minimizing introduction of distinct diffraction structure. A method for passive speckle-suppressing diffusion a light field originating from one or more coherent light beams may include refracting the light field, through a microlens array, to diffuse the light field, and imposing a spatially varying phase shift on the light field to decohere the light field without introducing any first-order diffraction components deflected beyond angle spread introduced by the microlens array.

Abstract: A low-height projector assembly includes a biconvex lens, a converging lens, an aperture stop, and a beam-steerer between the biconvex lens and the converging lens. The biconvex lens has a principal plane, a focal length, and a first optical axis. The converging lens has a second optical axis laterally offset from the first. The beam-steerer is configured to steer light from the biconvex lens to the converging lens. An aperture-stop plane intersects the second optical axis and the aperture stop. On the second optical axis, at least one of a front surface and a back surface of the converging lens is between the aperture-stop plane and the beam-steerer. The axial chief ray's propagation distance from the principal plane to the aperture stop differs from the focal length by less than half the depth of focus of the biconvex lens.
