  • Publication number: 20220028908
    Abstract: Various optoelectronic modules are described and include one or more optoelectronic devices. Each optoelectronic module includes one or more optoelectronic devices. Sidewalls laterally surround each optoelectronic device and can be in direct contact with sides of the optoelectronic device or, in some cases, with an overmold surrounding the optoelectronic device. The sidewalls can be composed, for example, of a vacuum injected material that is non-transparent to light emitted by or detectable by the optoelectronic device. The module also includes a passive optical element. Depending on the implementation, the passive optical element can be on a cover for the module, directly on a top surface of the optoelectronic device, or on an overmold surrounding the optoelectronic device. Methods of fabricating such modules are described as well, and can facilitate manufacturing the modules using wafer-level processes.

  • Publication number: 20210215827
    Abstract: The current disclosure describes a stereo imaging system that is configured to use Time-of-Flight (“Tof”) techniques to aid in stereoscopic image processing. One process disclosed uses ToF to aid in identifying the same elements (e.g., pixel clusters) in stereo image pairs by narrowing down search areas for matching. Another process uses ToF to aid in identifying the same elements in stereo image pairs where there a small amount texture making it difficult to find a match.

  • Patent number: 10928642
    Abstract: Structured light projection system includes an array of light emitting devices, which is configured to emit a pattern of light. A projection lens is configured to receive and project the pattern of light from the array to a first optical element. The first optical element alters the pattern of light to generate a first emitted pattern of light that is irregular. The first emitted pattern of light is transmitted to a second optical element that is configured to receive the first pattern of light and reproduce the first emitted pattern along a second emitted pattern, which comprises multiple instances of the first emitted pattern arranged in a tiled pattern.

  • Patent number: 10761192
    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.
