    Abstract: Optical encoding systems include a generalized cylindrical code scale having one or more regions with different light reflective properties. In an example process, a code scale can be created by coating an elongated generalized cylinder with one or more different layers of materials having different light reflective properties. Portions of these layers can be removed selectively in order to expose a particular overlying material and create a particular pattern of features having different optical characteristics (e.g., absorbing, specularly reflecting, diffusely reflecting).

    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.

    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.

    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.

    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.
