Abstract
Methods and apparatuses provide holographic contact-free imaging of aerosol particles in an efficient manner. One apparatus for holographic imaging of an aerosol particle may include: a delivery device configured to deliver the particle into a region; a light source for outputting a first beam of light and a second beam of light, wherein the first beam travels into the region producing a first light wave which is un-scattered by the particle and a second light wave that is scattered by the particle, and the second beam does not travel into the region; a beam splitter for combining the second beam with the scattered light of the first beam into combined interference light; an image sensor for sensing an interference pattern created by the combined interference light; and an image processor configured to generate an image of the aerosol particle based on the sensed interference pattern.
