Abstract: Image sensor modules include primary high-resolution imagers and secondary imagers. For example, an image sensor module may include a semiconductor chip including photosensitive regions defining, respectively, a primary camera and a secondary camera. The image sensor module may include an optical assembly that does not substantially obstruct the field-of-view of the secondary camera. Some modules include multiple secondary cameras that have a field-of-view at least as large as the field-of-view of the primary camera. Various features are described to facilitate acquisition of signals that can be used to calculate depth information.

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: This disclosure relates to illumination modules operable to increase the area over which an illumination source, such as a vertical-cavity surface-emitting laser or light-emitting diode, illuminates. Such illumination modules include a substrate having electrical contacts, an illumination source electrically connected to the substrate, a collimation assembly operable to collimate the light generated from the illumination source, a translation assembly operable to translate light over an area, and a mask assembly. In various implementations the illumination source may be rather small in area, thereby reducing the cost of the illumination module. Some implementations of the illumination module can be used for the acquisition of three-dimensional data in some cases, while in other cases some implementations of the illumination module can be used for other applications requiring projected light.

Abstract: The present disclosure describes optoelectronic modules that, in some implementations, address the need to combine precise measurements of scenes over a range of near and far distances. For example, an optoelectronic module can include a light emitter operable to direct modulated structured light onto a scene. The module includes an imager to receive reflected light signals from the scene. The imager includes demodulation pixels operable to provide amplitude and phase information based on the reflected light signals. Various techniques can be used to derive distance or three-dimensional information about the scene based on the signals from the pixels.

Abstract: Optical assemblies include a stack of optical elements each of which has one or more alignment features. Each alignment feature traces a respective curve along a surface of one of the optical elements. The alignment feature(s) of one optical element fit within the alignment feature(s) of the other. In some cases, the alignment features can help establish more precise lateral alignment of the optical elements.

Abstract: The present disclosure describes structured-stereo imaging assemblies including separate imagers for different wavelengths. The imaging assembly can include, for example, multiple imager sub-arrays, each of which includes a first imager to sense light of a first wavelength or range of wavelengths and a second imager to sense light of a different second wavelength or range of wavelengths. Images acquired from the imagers can be processed to obtain depth information and/or improved accuracy. Various techniques are described that can facilitate determining whether any of the imagers or sub-arrays are misaligned.
