Abstract: A device for detecting particles in air; said device comprising: a flow channel configured to allow a flow of air comprising particles through the flow channel; a light source configured to illuminate the particles, such that an interference pattern is formed by interference between light being scattered by the particles and non-scattered light from the light source; an image sensor configured to detect incident light, detect the interference pattern, and to acquire a time-sequence of image frames, each image frame comprising a plurality of pixels, each pixel representing a detected intensity of light; and a frame processor configured to filter information in the time-sequence of image frames, wherein said filtering comprises: identifying pixels of interest in the time-sequence of image frames, said pixels of interest picturing an interference pattern potentially representing a particle in the flow of air, and outputting said identified pixels of interest for performing digital holographic reconstruction.

Abstract: 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.
