Abstract: A method and apparatus for measuring a temperature of a substrate located in a semiconductor processing environment is disclosed. The substrate has a top surface and an edge surface, and is positioned in a prescribed location within the semiconductor processing environment. An infrared camera oriented to view one side of the edge surface of the substrate is triggered to obtain an infrared image of the one side of the edge surface of the substrate. The infrared image is processed to obtain a temperature profile of the substrate.

Abstract: An example system includes an infrared emitter to output infrared light towards a target, where the infrared light reflects from the target to produce reflected infrared light, and a detector to receive the reflected infrared light and to provide a signal based on the reflected infrared light. The system also includes a lighting system that includes a light emitter to output visible light, a mirror configured (i) to allow the visible light to pass through the mirror and to reflect the reflected infrared light onto the detector, or (ii) to allow the reflected infrared light to pass through the mirror and onto the detector and to reflect the visible light, and one or more optical elements configured to affect the visible light and the reflected infrared light.

Abstract: A general purpose sensor architecture integrating a surface enhanced Raman spectroscopy (SERS) substrate, a diffractive laser beam delivery substrate and a diffractive infrared detection substrate is provided that can be used to implement a low-cost, compact lab-on-a-chip biosensor that can meet the needs of large-scale infectious disease testing. The sensor architecture can also be used in any other application in which molecules present in the liquid, gaseous or solid phases need to be characterized reliably, cost-effectively and with minimal intervention by highly skilled personnel.

Abstract: An absorption spectrometer with self-referencing calibration takes two measurements along a first and second path having different distances through a sample while largely preserving all other aspects of the optical path and system constant. Comparing these two measurements allows extraction of the spectrum largely free from instrument-specific artifacts.

Abstract: Light mapping devices and systems for use in indoor or vertical farming are disclosed herein. In particular, a light detection device is provided that includes a plurality of light sensors configured for detecting light emitted from one or more light sources at distinct positions across a grow plane. The light detection device will also include a microcontroller and one or more signal routing circuit boards, or junctions, for making electrical connections between the light sensors and the microcontroller in a multiplex architecture to enable the microcontroller to cycle through and read the Lux values from each of the light sensors with sub-second frequency and in real-time. The light detection device may also be part of a light mapping system that converts the Lux values to PPFD and generates a heatmap of PPFD intensity at distinct locations across the grow plane. Also provided herein are methods of using the light detector device and/or the light mapping system to determine the PPFD distribution across a grow plane in 2-dimensions or 3-dimensions in order to adjust the lights and/or position of growing plants, if necessary, to ensure that each plant in the grow bed receives sufficient light for optimal growth.

Abstract: An optical detector module can be used to implement proximity sensing function by detecting ambient light outside of the optical detector module in accordance with a first detection threshold. An optical detector module can be further used to implement other active functions such as material detection (e.g., skin) or depth-sensing by emitting one or more optical signals (e.g., light pulses at a specific wavelength) and detecting the reflected optical signals relative to a second and/or third detection threshold. The disclosure provides technical solutions for actively monitoring detection threshold(s) of an optical detector module to achieve better power management. In some embodiments, such solutions are useful for photodetectors having a wide sensing bandwidth, such as a photodetector formed in germanium or a photodetector comprising an absorption region comprising germanium.

Abstract: A photoelectric conversion device includes a photodiode configured to perform avalanche multiplication, a recharging circuit configured to perform a recharging operation to bring the photodiode after the avalanche multiplication into a state in which the avalanche multiplication can be performed again based on a first control signal including pulses that periodically repeat transitions from a first level to a second level, and a counter configured to count the number of occurrences of the avalanche multiplication by being enabled based on a second control signal. Before the counter is enabled based on the second control signal, the first control signal transitions from the first level to the second level and transitions from the second level to the first level.
