Abstract: A time of flight-based system is operable for ambient light measurements. A method of operation includes detecting, in at least one active demodulation detection pixel, a first particular wavelength and generating amplitude data of the first particular wavelength; and detecting, in at least one spurious reflection detection pixel, a second particular wavelength and generating amplitude data of the second particular wavelength. In a computational device that stores spectrum data corresponding respectively to a plurality of different ambient light source types, an ambient lighting condition is determined based on the amplitude data of the first particular wavelength, the amplitude data of the second particular wavelength and the spectrum data of a particular one of the ambient light source types associated with the amplitude data of the first particular wavelength and the amplitude data of the second particular wavelength.

Abstract: Optoelectronic modules include a silicon substrate in which or on which there is an optoelectronic device. An optics assembly is disposed over the optoelectronic device, and a spacer separates the silicon substrate from the optics assembly. Methods of fabricating such modules also are described.

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. The light source (12) and photodetector (14) are mounted and electrically coupled to a substrate (16) that, in turn, can be mounted and electrically coupled to a printed circuit board (PCB) (18) of a host device. The light source (12) and photodetector (14) are surrounded laterally by a spacer or housing wall (20). The target surface (25) may be the backside of a touch interactive display screen (24) in the host device, e.g., a portable computing device such as a smartphone, tablet, wearable device, personal digital assistant (PDA), or personal computer. Circuitry (28) can be implemented, for example, as an integrated circuit chip or other processor and may include software and/or a look-up table stored in memory that allows the circuitry (28) to correlate the measured photodetector signal to a distance. When pressure is provided on the display screen (24) (e.g., by a person pressing her finger on the screen), the display screen is displaced slightly in the direction of the substrate (16) on which the light source (12) and photodetector (14) are mounted. As a result of the displacement, the intensity of light detected by the photodetector (24) changes. The signal measured by the photodetector (24) can be correlated to a distance value. If the distance value is within a specified range (or changes by at least a specified amount), for example, it can trigger some further action in the host device.

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.

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.

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.

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.
