  • Patent number: 11402202
    Abstract: An optoelectronic device has an asymmetric field overlap and is operable to measure proximity independently of object surface reflectivity. In some instances, the optoelectronic device includes a plurality of light-emitting assemblies and a light-sensitive assembly. In some instances, the optoelectronic devices include a plurality of light-sensitive assemblies and a light-emitting assembly. An asymmetric field overlap is attained in various implementations via various field-of-view axis, field-of-view angle, field-of-illumination axis, field-of-illumination angle, optical element and/or pitch configurations.

  • Publication number: 20220128688
    Abstract: An optical sensor module uses polarized light such that, in some instances, crosstalk effects caused by light reflected from a cover glass or from a thin smudge layer on the cover glass can be eliminated, or at least reduced, by directing light of a first polarization through the cover glass toward a target and selectively detecting, in the module, light of a second polarization that is orthogonal to the first polarization.

  • Patent number: 11307087
    Abstract: The present disclosure is directed to optoelectronic modules with substantially temperature-independent performance characteristics and host devices into which such optoelectronic modules can be integrated. In some instances, an optoelectronic module can collect proximity data using light-generating components and light-sensitive components that exhibit temperature-dependent performance characteristics. The light-generating components and light-sensitive components can be configured such that they exhibit complementing temperature-dependent performance characteristics such that the operating performance of the optoelectronic module is substantially temperature independent.

  • Publication number: 20220113464
    Abstract: Fabricating light guide elements includes forming a first portion of the light guide element using a replication technique (104), and forming a second portion of the light guide element using a photolithographic technique (106). Use of replication can facilitate formation of more complex-shaped optical elements as part of the light guide element. The replication process sometimes results in the formation of a “yard,” or excess replication material, which may lead to light leakage if not removed or smoothed over. In some instances, at least part of the yard portion is embedded within the second portion of the light guide element, thereby resulting in a smoothing over of the yard portion.

  • Publication number: 20220066573
    Abstract: Techniques are described for use with a wide range of consumer and other electronic devices to facilitate a user's control of such features as volume, as well as song, channel or page selection, depending on the application. A method includes emitting light out of a module, receiving signals from light detectors in the module, wherein the signals represent, at least in part, light reflected by a person's finger or other object passing in front of the light detectors, detecting movement of the person's finger or other object based on the received signals, and controlling a feature of a device in response to the detected movement.

  • Publication number: 20220035478
    Abstract: An apparatus, e.g. a proximity sensor module (10), for optical distance sensing includes a target surface (25) having a non-uniform design including a high-reflectivity region and a low-reflectivity region for light of a particular wavelength. The position of the target surface (25) is displaceable within the apparatus. The apparatus includes a light source (12) operable to emit light at the particular wavelength toward the target surface (25), and a photodetector (14) operable to sense at least some of the light emitted by the light source and subsequently reflected by the target surface (25). A processor is operable to correlate an output from the photodetector (14) with a distance to the target surface (25). A wall (22) may separate the light source (12) and photodetector (14) from one another, which can help reduce internal optical crosstalk.

  • Patent number: 11036309
    Abstract: The sensor (1) for determining an orientation of the sensor in a gravity field comprises a ball (2) and a rolling surface (R) describing a generally concave shape on which the ball can roll inside the sensor. A further surface (F) is arranged opposite said rolling surface, and a light emitter (E), a light detector (D) and another light emitter or detector is provided. A region (R) within which the ball (2) can move is limited by at least the rolling surface (R) and the further surface (F). And the light emitters (E) and detectors (D) are arranged outside the region (R) for emitting light through the rolling surface (R) into said region and detecting light exiting the region (3) through the rolling surface (R) or for emitting light through the further surface (F) into said region (R) and detecting light exiting said region (R) through the further surface (F). Corresponding measuring methods and manufacturing methods are described, too.

  • Patent number: 10908208
    Abstract: Testing apparatus operable to collect optical performance data of optoelectronic devices at different temperatures includes thermal-adjustment devices in thermal and mechanical contact with the optoelectronic devices via optoelectronic device stages. The thermal-adjustment devices can direct thermal energy to the optoelectronic devices under test without heating test targets in close proximity. Consequently, in some instances, spurious results can be avoided and rapid measurement of the optoelectronic devices different temperatures can be achieved.

  • Publication number: 20210018734
    Abstract: Light-emitting optoelectronic modules operable to generate an emission characterized by reduced speckle can include a coherent light source, a diffuser, and a Fresnel element. The coherent light source is operable to generate a coherent emission, characterized by a coherence length, incident on the diffuser. The diffuser is characterized by a divergence angle. The divergence angle is the angle between a first path-length from the diffuser to a Fresnel element and a second path-length from the diffuser to the Fresnel element, wherein their difference defines a path difference. In some instances, the path difference is substantially larger than the coherence length.

  • Publication number: 20200400423
    Abstract: Optoelectronic modules operable to measure proximity independent of object surface reflectivity and, in some implementations, operable to measure characteristics (such as surface reflectivity or absorptivity) of stationary or moving objects are disclosed. The optoelectronic modules are operable to determine, for example, pulse rate, peripheral blood circulation, and/or blood oxygen levels of moving objects, such as the appendage of a user, in some instances. The optoelectronic modules can be used to measure peripheral blood circulation, for example, when a user of the optoelectronic module is engaged in physical activity, such as walking, running or cycling.

  • Patent number: 10679976
    Abstract: Compact optoelectronic modules are described that, in some implementations, can have reduced heights, while at the same time having very little optical crosstalk or detection of stray light. An optoelectronic module having optical channel can include a support on which is mounted an optoelectronic device arranged to emit or detect light at a particular one or more wavelengths. The module has a cover including an optically transmissive portion over the optoelectronic device. The optically transmissive portion is surrounded laterally by sections of the cover that are substantially non-transparent to the one or more wavelengths. A passive optical element is present on a surface of the optically transmissive portion. A spacer separates the support from the cover. The cover can be relatively thin so that the overall height of the module is relatively small.

  • Patent number: 10488264
    Abstract: The present disclosure describes optical radiation sensors and detection techniques that facilitate assigning a specific wavelength to a measured photocurrent. The techniques can be used to determine the spectral emission characteristics of a radiation source. In one aspect, a method of determining spectral emission characteristics of incident radiation includes sensing at least some of the incident radiation using a light detector having first and second photosensitive regions whose optical responsivity characteristics differ from one another. The method further includes identifying a wavelength of the incident radiation based on a ratio of a photocurrent from the first region and a photocurrent from the second region.
