  • Publication number: 20180059246
    Abstract: An optoelectronic module includes a first light emitter operable to emit radiation at a first wavelength toward an object outside the module. The module also includes demodulation pixels operable to detect radiation of the first wavelength reflected from the object. One or more processors are operable to determine a distance to the object based on the radiation detected by the demodulation pixels. The module is further operable to perform a supplemental measurement other than distance.

  • Publication number: 20180026020
    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: 9859327
    Abstract: Various optoelectronic modules are described that include an optoelectronic device (e.g., a light emitting or light detecting element) and a transparent cover. Non-transparent material is provided on the sidewalls of the transparent cover, which, in some implementations, can help reduce light leakage from the sides of the transparent cover or can help prevent stray light from entering the module. Fabrication techniques for making the modules also are described.

  • Publication number: 20170248472
    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.

  • Patent number: 9658109
    Abstract: Compact thermal sensor modules, which in some implementations can be manufactured in wafer-level fabrication processes, include features composed of or coated with a low-emissivity material to reduce or prevent detection by a sensor of radiation emitted by other parts of the module. For example, spacers that separate an optics substrate and a sensor package from one another can be composed of or coated with such a low emissivity material. In some cases, the low emissivity material has an emissivity of no more than 0.1.

  • Publication number: 20170135617
    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).

  • Patent number: 9613939
    Abstract: Opto-electronic modules, which can be fabricated in a wafer-scale process, include light emitting and/or light sensing devices mounted on or in a substrate. The modules, which can include various features to help reduce the occurrence of optical cross-talk and help prevent interference from stray light, can be used in a wide range of applications, including medical and health-related applications. For example, performing a measurement on a human body can include bringing a portion of the human body into direct contact with an exterior surface of the opto-electronic module and using a differential optical absorption spectroscopy technique to obtain an indication of a physical condition of the human body.

  • Publication number: 20170089757
    Abstract: An optoelectronic module that includes a reflectance member which exhibits mitigated or eliminated fan-out field-of-view overlap can be concealed or its visual impact minimized compared to a host device in which the optoelectronic module is mounted. In some instances, the reflectance member can be implemented as a plurality of through holes and in other instances the reflectance member may be a contiguous spin-coated polymeric coating. In general, the reflectance member can be diffusively reflective to the same particular wavelengths or ranges of wavelengths as the host device in which it is mounted.

  • Publication number: 20160223746
    Abstract: The waveguide structure can be manufactured on wafer-scale and comprises a holding structure and a first and a second waveguides each having a core and two end faces. The holding structure comprises a separation structure being arranged between the first and the second waveguide and provides an optical separation between the first and the second waveguide in a region between the end faces of the first and second waveguides. A method for manufacturing such a waveguide structure with at least one waveguide comprises shaping replication material by means of tool structures to obtain the end faces, hardening the replication material and removing the tool structures from a waveguide structures wafer comprising a plurality of so-obtained waveguides.

  • Publication number: 20160216777
    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.
