Abstract: An infrared spectrometer for operation in the mid-infrared spectral range is presented, where the spectrometer includes a Bragg-mirror-based spectral filter that is operative for providing an interrogation signal whose spectral content is dispersed along a first direction at a filter aperture. The filter aperture is imaged through a sample by a thermal-imaging camera to create a focused image that is based on the interrogation signal and the absorption characteristics of the sample. As a result, embodiments in accordance with the present disclosure can be smaller, less complex, and less expensive than infrared spectrometers known in the prior art.

Abstract: Melanopic dose rate and dose are calculated in a virtual environment. A computer generated model of an actual or planned building is used as the virtual environment. Indirect and direct spherical irradiances are calculated using convex polyhedra throughout the virtual environment, and each is multiplied by a melanopic conversion factor. The two are added, then adjusted for a human's angular responsivity and age. Building design features or lighting devices may be adjusted to provide a required melanopic dose rate. A camera is used to capture a panoramic image, which is calibrated to tristimulus values, and used with the spectral power distribution of the light sources to derive the melanopic dose rate.

Abstract: Disclosed is an instrument including a multipath, monolithic optical component, made up of a portion of a transparent material between two opposite faces of the component. One of the two faces of the component is formed by a first refracting surface, and the other face includes several second refracting surfaces which are juxtaposed. Each optical path of the component is formed by one of the second refracting surfaces in combination with a corresponding portion of the first refracting surface. One such component is suited for being part, within the instrument, of a detection module with multiple optical paths arranged in parallel, with a matrix photodetector shared by the optical paths. Such a detection module may be compact enough in order to be integrated into a cryostat cold screen, improving cooling thereof, and may be combined with an objective in order to form an instrument with multiple optical paths.
