摘要： An apparatus for producing structured light comprises a first optical arrangement which comprises a microlens array (L1) comprising a multitude of transmissive or reflective microlenses (2) which are regularly arranged at a lens pitch P and an illumination unit for illuminating the microlens array. The illumination unit comprises an array (S1) of light sources (1) 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
2 = 2LD/N, wherein N is an integer with N ≥ 1. High- contrast high-intensity light patterns can be produced. Devices comprising such apparatuses can be used for depth mapping.

摘要： An optoelectronic module includes a spacer with an optical component mounting surface, a fluid permeable channel, and a module mounting surface. The fluid permeable channel and module mounting surface allow the channels to be sealed to foreign matter during certain manufacturing steps and to remain free from blockages, such as solidified flux, during certain manufacturing steps. Further, the channels can permit heat to escape from the optoelectronic module during operation.

摘要： The illumination module for emitting light (5) can operate in at least two different modes, wherein in each of the modes, the emitted light (5) has a different light distribution. The module has a mode selector (10) for selecting the mode in which themodule operates, and it has an optical arrangement. The arrangement includes - a microlens array (LL1) with a multitude of transmissive or reflective microlenses (2) which are regularly arranged at a lens pitch P (P1); - an illuminating unit for illuminating the microlens array (LL1).The illuminating unit includes a first array of light sources (S1) operable to emit light of a first wavelength L1 each and having an aperture each. The apertures are located in a common emission plane which is located at a distance D (D1) from the microlens array (LL1). In a first one of the modes, for the lens pitch P, the distance D and the wavelength L1 appliesP2 = 2⋅L1⋅D/N wherein N is an integer with N ≥ 1.
