The illumination module for emitting light () can operate in at least two different modes, wherein in each of the modes, the emitted light () has a different light distribution. The module has a mode selector () for selecting the mode in which the module operates, and it has an optical arrangement. The arrangement includes&#x2014;a microlens array (LL) with a multitude of transmissive or reflective microlenses () which are regularly arranged at a lens pitch P (P);&#x2014;an illuminating unit for illuminating the microlens array (LL). The illuminating unit includes a first array of light sources (S) operable to emit light of a first wavelength Leach and having an aperture each. The apertures are located in a common emission plane which is located at a distance D (D) from the microlens array (LL). In a first one of the modes, for the lens pitch P, the distance D and the wavelength Lapplies P=2&#xb7;L&#xb7;D/N wherein N is an integer with N&#x2265;1.

Multi-mode illumination module and related method

An apparatus for producing structured light comprises a first optical arrangement which comprises a microlens array (L) 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 (S) 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 P=2LD/N, wherein N is an integer with N&#x2265;1. High-contrast high-intensity light patterns can be produced. Devices comprising such apparatuses can be used for depth mapping.

Apparatus for producing patterned illumination using arrays of light sources and lenses

A brightness image of a scene is converted into a corresponding frequency domain image and it is determined whether a threshold condition is satisfied for each of one or more regions of interest in the frequency domain image, the threshold condition being that the number of frequencies in the region of interest is at least as high as a threshold value. The results of the determination can be used to facilitate selection of an appropriate block matching algorithm for deriving disparity or other distance data and/or to control adjustment of an illumination source that generates structured light for the scene.

Three-dimensional imaging using frequency domain-based processing

Optoelectronic systems include an array of optoelectronic modules and a computational unit. The array of optoelectronic modules and the computational unit are operable to collect data of a user of the optoelectronic system. The data can be used, for example, to authenticate the identity of the user by being used in multiple user authentication protocols. In some instances, facial recognition data can be augmented with three-dimensional data of the user and can be combined with iris recognition data to authenticate the identity of the user. Such optoelectronic systems can comprise hardware authentication systems external to auxiliary devices such as tablet computers and laptop computers.
