Abstract: An infrared scene generator can generate a second infrared scene representative of a first infrared scene by emitting a beam of electromagnetic radiation onto a plurality of prism-coupled electrically conductive elements that modulate a portion of the beam incident thereon with surface plasmon polaritons based on parameters of the first infrared scene to yield a modulated beam that produces the second infrared scene.

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.

Abstract: Presented here is a system to record high-resolution infrared images without the need to include additional stand-alone sensors into the mobile device. According to one embodiment, an organic light emitting diode (OLED) display is modified to emit IR and near-IR light in a large field. The modified display allows for depth sensing and infrared imaging without a stand-alone emitter. Additionally, an IR shutter filter can be applied to the existing front facing red, green, blue (RGB) camera that would only be in place when the display is in IR emission mode. The combination of these two technologies allows a facial recognition system using existing hardware, and not require additional sensors or emitters to achieve face recognition.

Abstract: A flame sensor detects the presence of a flame in a combustion system in which the flame emits light. The flame sensor includes a body connectable with the combustion system. A photodetector is supported in the body. The photodetector responds to light emitted by the flame and generates an electrical signal proportional to an intensity of the light. A window is supported in the body and located between the combustion system and photodetector. The window is susceptible to contamination from the combustion system and the contamination may decrease sensitivity of the photodetector. A light source is supported in the body. The light source emits light so that a predetermined amount of the light emitted by the light source reflects into the photodetector when contamination is present on the window and the photodetector generates a signal indicative of contamination on the window.

Abstract: An assembly line in-situ calibration arrangement, optical sensor arrangement and a method for calibration of an optical sensor arrangement are presented. A calibration arrangement comprises a calibration head comprising at least one calibrated light source located behind an aperture in a housing and being electrically connected to a power terminal. A power source is connected to the power terminal, the power source comprising a switching unit electrically connected to the at least one light source. An interface unit is connected to the switching unit by means of an interface connection, wherein the interface unit is arranged to control the switching unit. A control unit is connected to the interface unit, wherein the control unit is arranged to drive the interface unit such that the at least one light source is switched to emit a calibration pulse sequence to be received by the optical sensor arrangement to be placed with respect of the aperture. The calibration pulse sequence is arranged to initiate a calibration mode of operation of the optical sensor arrangement.
