Abstract: A device, for emitting and controlling infrared light, comprises a substrate extending between a bottom surface and a top surface. A cavity is provided in the substrate, the cavity opening onto the top surface. A light source extends over the cavity and is able to heat up when passed through by an electric current, so as to emit infrared light. A cover covers the substrate, the cover and the substrate forming a first component enclosing the light source. The light source delineates a first half space comprising the cover, and a second half space comprising the cavity and the bottom surface of the substrate.

Abstract: Systems for protein quantitation using a Fabry-Perot interferometer. In one arrangement, a quantitation device includes an infrared source, a sample holder, and a Fabry-Perot interferometer positioned to receive infrared radiation from the source passing through a sample on the sample holder. A band pass optical filter sets the working range of the interferometer, and radiation exiting the interferometer falls on a detector that produces a signal indicating the intensity of the received radiation. A controller causes the interferometer to be tuned to a number of different resonance wavelengths and receives the intensity signals, for determination of an absorbance spectrum.

Abstract: Methods and apparatus are presented for measuring a photoluminescence (PL) response, preferably a spatially resolved image of a PL response, from an object exposed to solar irradiation. In certain embodiments signals from the object are measured in two or more different spectral bands selected such that one of the measured signals has a higher PL component relative to ambient reflectance compared to another measured signal, enabling the PL component to be enhanced by a suitable differencing procedure. In other embodiments a signal from an object is measured in a spectral band selected such that at least 20% of the measured signal comprises PL generated from the object by the solar irradiation. The methods and apparatus have particular application to outdoor inspection of photovoltaic modules without having to modulate the operating point of the modules.

Abstract: Some examples herein include systems and methods of creating standards of gemstones of various classifications, which may display certain characteristics of the various classifications when excited by ultraviolet radiation and fluoresce in response. In some examples, a set of standards are created using fluorescent material, filters, and a radiation source to compare against a sample gemstone.

Abstract: Systems and methods for verifying that light absorption is caused by a targeted gaseous chemical compound. A first transmittance of light, either generated at, or filtered to, a first wavelength range and a second transmittance of light, either generated at, or filtered to, a second wavelength range are measured by first and second photon detectors. A ratio of the first and second measured transmittance is determined and that ratio is compared to a transmittance ratio associated with a targeted gaseous chemical compound to verify that the light absorption is caused by the targeted gaseous chemical compound.

Abstract: Methods for reliable identification of low-contrast lesions within a tissue of a subject comprise delivering an excitation signal to the tissue, wherein the excitation signal is selected to stimulate tissue to produce autofluorescence and/or reflectance. The autofluorescence and/or reflectance is detected, and ratiometric images are produced based on the autofluorescence and/or reflectance images. An imaging system is provided which is configured to carry out such methods, irradiating tissue at a various possible excitation wavelengths, such as UV excitation wavelengths below 300 nm, to elicit fluorescence from specific native fluorophores.

Abstract: A gas concentration measurement device measures a gas concentration based on an absorbance of sample gas in a region between a light source that emits infrared light and a detector that detects the infrared light. The gas concentration measurement device includes a rotating member, first and second band pass filters on the rotating member, and a rotational driver. The first and second band pass filters are located on a pair of planes that intersect each other. The rotational driver rotates the rotating member around the rotating shaft to switch between a first state, in which the infrared light from the light source is transmitted through the first band pass filter, and a second state, in which the infrared light from the light source is transmitted through the second band pass filter.
