  • Publication number: 20210014429
    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.

  • Patent number: 10371954
    Abstract: The present disclosure describes optoelectronic modules (e.g., hybrid lens array packages) that have multiple optical channels, each of which includes at least one beam shaping element (e.g., a lens) that is part of a laterally contiguous array. Each optical channel is associated with a respective light sensitive region of an image sensor. Some or all of the channels also can include at least one beam shaping element (e.g., a lens) that is not part of a laterally contiguous array. In some cases, the arrays can include alignment features to facilitate alignment of the arrays with one another.

  • Patent number: 10359505
    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.

  • Publication number: 20190049097
    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).

  • 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).
