Compact infrared countermeasure emitter

A semiconductor laser produces infrared radiation suitable for jamming a heat seeking missile, wherein a wavelength of the radiation is in a range of 2-5 microns, and the laser has a semiconductor lasing medium of Pb1-xSexPb1-xSnxSe or Ga0.84In0.16As0.14Sb0.86. These materials can be doped to provide a p/n junction, wherein the laser is excitable by electric current passing through the p/n junction. The third one of these materials can be constructed also as a uniform undoped slab which is excitable optically. Cooling of the lasing medium is accomplished by use of a lithium heat sink thermally coupled to the lasing medium by a diamond thermal diffuser which conducts heat from the relatively small region of the laser to spread out the thermal energy along a relatively large surface of the heat sink. Modulation circuitry is connected to the excitation apparatus to provide a pulse train of the radiation.

Electronic Devices Having Infrared-Transparent Window Coatings

An electronic device may have a display with a cover layer. A light-based component such as an infrared-light proximity sensor or other infrared-light-based component may be aligned with a window in the display cover layer. The window may block visible light and transmit infrared light. A coating in the window may include a thin-film filter formed from a stack of inorganic dielectric layers. The thin-film filter may block visible light and transmit infrared light. The coating may also include at least one layer of material such as a semiconductor material that absorbs visible light and that passes infrared light. This material may be interposed between the thin-film filter and the display cover layer. Antireflection properties and color adjustment properties may be provided using thin-film layers between the thin-film filter and the display cover layer.

Jupiter looks pretty angry in "lucky" infrared shot

It took hundreds of exposures and a complex method of removing occlusions, but this "lucky" shot is the result: a depiction of the hot regions lurking under Jupiter's uppermost clouds.

The picture was captured in infared by the Gemini North Telescope in Hawaii, and is one of the sharpest observations of the planet ever made from the ground. To achieve the resolution, scientists used a technique called "lucky imaging" which scrubs out the blurring effect of looking through Earth's turbulent atmosphere. This method involves acquiring multiple exposures of the target and only keeping those segments of an image where that turbulence is at a minimum.

Near-Infrared Imaging in Intravenous Cannulation in Children: A Cluster Randomized Clinical Trial

Gaining intravenous access in children can be difficult. Recently, several near-infrared devices have been introduced attempting to support intravenous cannulation by visualizing veins underneath skin. Only one of those devices has been evaluated systemically thus far and results are inconclusive.

Although it was possible to visualize veins with near-infrared in most patients, the VascuLuminator did not improve the success of cannulation. An explanation is that the main problem is probably not localization of the vein but insertion of the cannula. (Read the full article)

Fourier Transform Infrared Spectroscopy Is a New Option for Outbreak Investigation: a Retrospective Analysis of an Extended-Spectrum-Beta-Lactamase-Producing Klebsiella pneumoniae Outbreak in a Neonatal Intensive Care Unit [Epidemiology]

The IR Biotyper is a new automated typing system based on Fourier-transform infrared (FT-IR) spectroscopy that gives results within 4 h. We aimed (i) to use the IR Biotyper to retrospectively analyze an outbreak of extended-spectrum beta-lactamase-producing Klebsiella pneumoniae (ESBL-KP) in a neonatal intensive care unit and to compare results to BOX-PCR and whole-genome sequencing (WGS) results as the gold standard and (ii) to assess how the cutoff values used to define clusters affect the discriminatory power of the IR Biotyper. The sample consisted of 18 isolates from 14 patients. Specimens were analyzed in the IR Biotyper using the default analysis settings, and spectra were analyzed using OPUS 7.5 software. The software contains a feature that automatically proposes a cutoff value to define clusters; the cutoff value defines up to which distance the spectra are considered to be in the same cluster. Based on FT-IR, the outbreak represented 1 dominant clone, 1 secondary clone, and several unrelated clones. FT-IR results, using the cutoff value generated by the accompanying software after 4 replicates, were concordant with WGS for all but 1 isolate. BOX-PCR was underdiscriminatory compared to the other two methods. Using the cutoff value generated after 12 replicates, the results of FT-IR and WGS were completely concordant. The IR Biotyper can achieve the same typeability and discriminatory power as genome-based methods. However, to attain this high performance requires either previous, strain-dependent knowledge about the optimal technical parameters to be used or validation by a second method.
