摘要: An example method and hyperspectral imaging (HSI) system for imaging a scene are provided. The method is for imaging the scene with the HSI system including a sensor with a plurality of sensor pixels and a plurality of spectral filters, each of the spectral filters being associated with one of the sensor pixels. The method comprises obtaining a higher-resolution spatial image by illuminating the scene with a first set of wavelengths, wherein each spectral filter passes the first set of wavelengths to the sensor pixel it is associated with. The method further comprises obtaining a lower-resolution hyperspectral image by illuminating the scene with a second set of wavelengths, wherein each spectral filter passes only a subset of the second set of wavelengths to the sensor pixel it is associated with.

摘要: The inventive concept relates to a collector for collecting particles in air and a device for detecting particles in air comprising said collector. Said collector comprises a substrate, which is adapted to enable imaging of the particles, an adhesive layer arranged on a collector side of the substrate, said adhesive layer being formed by an adhesive material. The collector further comprises a protection element, which is configured to protect the adhesive layer before collection of particles. The collector is configured to allow release of protection of the adhesive layer by the protection element to expose an adhesive surface of the adhesive layer to ambient air for collecting particles on the adhesive surface. The collector is further configured for presenting a particle sample carrier having a smooth top surface and a smooth bottom surface for preventing light from being diffusely scattered by the particle sample carrier.
