Near-infrared spectroscopy and imaging are non-invasive optical methods, which measure various parameters such as the absorption and scattering coefficient of tissue and the concentration of oxy and deoxyhemoglobin, water and fat. Near-infrared spectroscopy and imaging offer the possibility to non-invasively measure hemodynamic responses of the brain to external stimuli. The ability of near-inf...

A discussion of CMOS readout technologies for infrared (IR) imaging systems is presented. First, the description of various types of IR detector materials and structures is given. The advances of detector fabrication technology and microelectronics process technology have led to the development of large format array of IR imaging detectors. For such large IR FPA’s which is the critical componen...

Many thermal imaging applications stand to gain from the inclusion of multispectral capabilities in the long wave infrared (LWIR). While infrared spectral imaging systems presently exist, the addition of multispectral capabilities will provide a number of advantages, including the ability to accurately quantify the temperature distribution a scene, and the potential for dramatically improved ta...

Face recognition is a wide area having many techniques to achieve the same. The aim of the paper is to introduce Thermal Imaging and to study how it can be used for facial recognition and also for deception detection. This paper looks into the single modal and multi modal face recognition techniques involving infrared (IR) imaging. It then moves to analyze facial variations to study deception u...

This paper proposes a method to detect air pollution by applying hyperspectral imaging algorithm for visible light, near infrared, and far infrared. By assigning information images from monocular, thermal imaging, principal component analysis is performed on taken at different times obtain the solar radiation intensity. The Beer–Lambert law multivariate regression are used calculate PM2.5 PM10 ...

Scan and deliver: By combining imaging-based spectral/spatial 2D radiofrequency manipulations (see scheme, left) with Hadamard-weighting principles, 2D NMR spectra can be retrieved within a single scan (right). This approach can give homo- or heteronuclear correlations with an enhanced sensitivity over conventional ultrafast 2D NMR spectroscopy.

A reference-free image index to jointly assess infrared-imaging fixed-pattern-noise and blur artifacts is proposed in this work. The based on tuned-spatial-domain filtering, which works by combining two Laplace operators simultaneously quantify the global or local artifacts. effectiveness demonstrated task-based image-quality assessments determine focused free images from sequences captured wit...

Near-infrared light is favourable for imaging in mammalian tissues due to low absorbance of hemoglobin, melanin, and water. Therefore, fluorescent proteins, biosensors and optogenetic constructs for optimal imaging, optical readout and light manipulation in mammals should have fluorescence and action spectra within the near-infrared window. Interestingly, natural Bacterial Phytochrome Photorece...
