A mobile thermal sensor system, a mobile device case, and a process for fabricating a mobile thermal sensor system are described that include using a heat spreader (e.g., a heat sink). In an implementation, the mobile thermal sensor system includes a substrate configured to support an electrical component; a thermal detector package coupled to the substrate, the thermal detector package including a first thermopile, a second thermopile, and a reference temperature detector; and a heat spreader coupled to the substrate. In another implementation, a mobile device case can include a case configured to house a mobile device, where the mobile device includes a mobile thermal sensor system.

An optical apparatus is disclosed, the apparatus comprising an optical element having a reflective surface for reflecting incident radiation in a beam path, and at least one sensor configured to sense radiation corresponding to a temperature of a respective portion of a backside surface of the optical element. Also disclosed is a method of controlling a temperature of a reflective surface of an optical element in a lithographic apparatus.

An infrared detection element includes a pyroelectric body, first and second light receiving electrodes, and blackened films. The first light receiving electrode is provided on a surface of the pyroelectric body and receives infrared light from a first region. The second light receiving electrode is provided on a surface of the pyroelectric body and receives infrared light from a second region. The blackened films are provided on a surface of the first light receiving electrode and are not provided on a surface of the light second receiving electrode. Thus, infrared reception sensitivity is different between the first light receiving electrode and the second light receiving electrode.

The present disclosure relates to an apparatus for simulating a black body spectrum. The apparatus makes use of a broadband light source and a light guide configured to receive light generated by the light source and to generate first and second optical signals. A first signal processing subsystem may be used to enable adjustment of both a signal spectrum and an intensity of the first optical signal. A second signal processing subsystem may be used to enable adjustment of both a signal spectrum and an intensity of the second optical signal. A beam cube may be used to combine the first and second optical signals to produce a final light output signal having a desired signal spectrum and a desired intensity.

An annealing object is held at a position on which a laser beam output from a laser light source is incident. An infrared detector detects heat radiation light from the annealing object. An optical element which does not allow light having a wavelength shorter than 1 m to be incident on the infrared detector is disposed in a pathway of the heat radiation light from the annealing object to the infrared detector.

A series of time-sequenced heat energy data arrays or data stream sets of a weld process region are processed by a weld data array or data stream processing system to produce a heat energy data set output that is related to weld process region features or weld process region heat energy data. The heat energy data set output can be displayed to a system user and modified by system user input to the weld data array or data stream processing system; alternatively, or in combination, the system user output and input, the heat energy data set output, or data produced from the heat energy data set output by the weld data array or data stream processing system, can be transmitted to a weld process controller to adjust parameters in the weld process responsive to the output of the weld data array or data stream processing system.

An annealing object is held at a position on which a laser beam output from a laser light source is incident. An infrared detector detects heat radiation light from the annealing object.

A motion detection system including a lens arranged to focus infrared radiation; a variably positionable optical attenuator arranged for variable positioning thereof opposite the focusing lens, operable for variably attenuating infrared radiation focused by the focusing lens, an extent and a magnitude of the variable attenuation being dependent on a position and on a set of physical characteristics of the variably positionable optical attenuator; a PIR sensor positioned opposite the focusing lens and the variably positionable optical attenuator, operable for sensing the focused and attenuated infrared radiation; and a human motion detection indication generator operable for ascertaining whether an intensity of infrared radiation sensed by the PIR sensor is above a human-generated infrared radiation detection threshold and, responsive thereto, for generating an indication of detection of human motion.
