Abstract: 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 the module 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 applies P2=2·L1·D/N wherein N is an integer with N≥1.

Abstract: The present disclosure describes optical imaging and optical detection modules that include sensors such as time-of-flight (TOF) sensors. Various implementations are described that, in some instances, can help reduce the amount of optical cross-talk between active detection pixels and reference pixels and/or can facilitate the ability of the sensor to determine an accurate phase difference to be used, for example, in distance calculations.

Abstract: This disclosure describes various modules that can provide ultra-precise and stable packaging for an optoelectronic device such as a light emitter or light detector. The modules include vertical alignment features that can be machined, as needed, during fabrication of the modules, to establish a precise distance between the optoelectronic device and an optical element or optical assembly disposed over the optoelectronic device.

Abstract: The present disclosure describes modules operable to perform optical sensing. The module can be operable to distinguish between signals indicative of reflections from an object or interest and signals indicative of a spurious reflection such as from a smudge (i.e., a blurred or smeared mark) on the host device's cover glass. Signals assigned to reflections from the object of interest can be used to for various purposes, depending on the application (e.g., determining an object's proximity, a person's heart rate or a person's blood oxygen level).

Abstract: 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 P2=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.

Abstract: Optoelectronic modules (100) are operable to distinguish between signals indicative of reflections from an object of interest and signals indicative of a spurious reflection. Various modules are operable to recognize spurious reflections by means of dedicated spurious-reflection detection pixels (126) and, in some cases, also to compensate for errors caused by spurious reflections.
