Abstract: A device and method for detecting the level of a compound in tissue, the device including: an illumination source operable to emit light from an optical opening into the tissue; a detector array having a plurality of photosites, each operable to detect light of the illumination source travelling through the tissue; wherein different photosites of the detector array are located at different distances from the optical opening; and a processor adapted for determining compound levels in the tissue based on differences in detected illumination levels at distinct wavelengths at different distances from the optical opening.

Abstract: Systems and methods for detection of hazardous media on roads. A system may comprise a imaging receiver operating in the short wave infrared range (SWIR) and including a focal plane array (FPA) and a polarization filter array (PFA) comprising micro-polarizers, and an analysis module for analyzing SWIR image data obtained under passive or active illuminations conditions for detection of hazardous media on a road, wherein the hazardous media includes ice. In some embodiments, the FPA comprises germanium-on-silicon photodetectors (PDs). In some embodiments, the micro-polarizers are integrated with the PDs.
