Systems, methods, and apparatus for providing electromagnetic radiation sensing. The apparatus includes a radiation detection sensor including a plurality of micromechanical radiation sensing pixels having a reflecting top surface and configured to deflect light incident on the reflective surface as a function of an intensity of sensed radiation. In some implementations, the apparatus has equal sensitivities for at least some of the sensing pixels. In some implementations, the apparatus can provide adjustable sensitivity and measurement range. The apparatus can be utilized for human detection, fire detection, gas detection, temperature measurements, environmental monitoring, energy saving, behavior analysis, surveillance, information gathering and for human-machine interfaces.

Embodiments disclosed herein generally relate to a substrate temperature monitoring system in a substrate support assembly. In one embodiment, the substrate support assembly includes a support plate and a substrate temperature monitoring system. The support plate has a top surface configured to support a substrate. The substrate temperature monitoring system is disposed in the substrate support plate. The substrate temperature monitoring system is configured to measure a temperature of the substrate from a bottom surface of the substrate. The substrate temperature monitoring system includes a window, a body, and a temperature sensor. The window is integrally formed in a top surface of the support plate. The body is embedded in the support plate, through the bottom surface. The body defines an interior passage. The temperature sensor is disposed in the interior passage beneath the window. The temperature sensor is configured to measure the temperature of the substrate.

An infrared thermometer measures a temperature of an energy zone. The infrared thermometer comprises a beam splitter for splitting an incident light beam from an energy zone into an infrared light beam and a visible light beam; an infrared detector for detecting the infrared light beam and generating a signal indicative of a temperature of the energy zone according to the detected infrared light beam; and a sighting device having an optical module for generating a reflective reticle image and transmitting the visible light beam to generate a target image at a sight window, wherein the sighting device is configured to superimpose the reflective reticle image over the target image at the sight window to align the infrared detector with the energy zone. The infrared thermometer and an associated measurement method facilitate the alignment of the energy zone by the users, thereby improving the accuracy of the measurement.

An electronic camera system is operable in a first operating state, in which a video signal delivered by the image sensor is based on the detection of visible light only, and a second operating state, in which a video signal delivered by the image sensor is at least in part based on the detection of infrared light. The camera system includes an electronic image sensor that is sensitive to visible light and infrared light, a lens system that is transparent to visible light and infrared light and serves for projecting an image onto the image sensor and a filter assembly arranged in front of the image sensor.

An electronic device may have light-based components. The light-based components may include light sources, light detectors, and image sensors. The light-based components may be aligned with a window in the device. The window may be formed within an inactive area of a display or within other device structures. The window may have one or more window members mounted within an opening in a display layer in the inactive area. Visible light blocking material such as chalcogenide glass may be incorporated into the window to provide the window with an opaque appearance that matches the opaque appearance of surrounding portions of the inactive portion of the display. In configurations in which the light-based components include a visible image sensor or other visible light detecting component, the window may be provided with a portion that is transparent at visible wavelengths.
