Abstract: A device and method are provided for determining the bulk (average) temperature, surface temperature, temperature profile, and thickness of radiation translucent materials. These material functions are determined by evaluation of the intensity of the radiation emitted from the material using two detectors with a radiation source placed in the optical path of one of the detectors. The data is taken at several intensities of source radiation and reduced to obtain the bulk temperature and material thickness. The second detector is used to measure the surface temperature. These data are then used to determine the temperature profile in the material.

Abstract: Described herein are systems and methods for detecting a physiological response based on multispectral data. In one embodiment, a system includes an inward-facing head-mounted thermal camera (CAM) that takes thermal measurements of a first region of interest (THROI1) on a user's face, and an inward-facing head-mounted visible-light camera (VCAM) that takes images of a second region of interest (IMROI2) on the face. The first and second regions of interest overlap, and the system includes a computer that detects the physiological response based on THROI1, IMROI2, and a model. Optionally, the model was trained based on previous THROI1 and IMROI2 of the user taken during different days. Optionally, the physiological response is indicative of an occurrence of an emotional state of the user, such as joy, fear, sadness or anger.

Abstract: Described herein are systems and methods for detecting a physiological response based on thermal measurements while accounting for effects of the environment. In one embodiment, a system includes an inward-facing head-mounted thermal camera (CAMin) that takes thermal measurements of a region of interest (THROI) on a user's face, and an outward-facing head-mounted thermal camera (CAMout) that takes thermal measurements of the environment (THENV). CAMin does not occlude the region of interest, and the system further includes a computer that detects the physiological response based on THROI and THENV. Optionally, the computer generates feature values based on sets of THROI and THENV, and utilizes a machine learning-based model to detect, based on the feature values, the physiological response.

Abstract: Techniques are provided for an image processing device to receive image information comprising image data for a plurality of mid-wave infrared region (MWIR) channels, where the image data is obtained during a first imaging period and during a second imaging period temporally different from the first imaging period. A plurality of sets of atmospheric wind vectors are calculated using differences between image data obtained during the first imaging period and the image data obtained during the second imaging period for corresponding sets of MWIR channels. An altitude is assigned to the plurality of atmospheric wind vectors in each set based on a brightness temperature of each wind vector and a pre-computed atmospheric temperature profile to generate a set of two-dimensional wind fields comprising one two-dimensional wind field for each set of MWIR channels.
