Abstract: An illumination module for generating a patterned illumination with minimal ambiguity includes an array of light sources having different respective near-field intensity profiles. The illumination module also includes an optical assembly. The optical assembly and the array of light sources can be operable to substantially replicate the different respective near-field intensity profiles of the light sources in the far-field thereby generating a patterned illumination. The patterned illumination can exhibit reduced ambiguity in some instances.

Abstract: An apparatus for producing structured light comprises a first optical arrangement which comprises a microlens array comprising a multitude of transmissive or reflective microlenses which are regularly arranged at a lens pitch P and an illumination unit for illuminating the microlens array. The illumination unit comprises an array of light sources for emitting light of a wavelength L each and having an aperture each, wherein the apertures are located in a common emission plane which is located at a distance D from the microlens array. For the lens pitch P, the distance D and the wavelength L, the following equation applies P2=2LD/N, wherein N is an integer with N≧1. High-contrast high-intensity light patterns can be produced.
