WebbIn-line holography relates to the original holographic scheme proposed by Gabor [1, 2, 3]. It is of conceptually simple design, does not include optical elements between sample and detector and has been employed since its invention in numerous experiments using various types of waves, be it light, electrons or X-rays, to name just a few.

"WebbIn line-holography permits only the view of silhouettes (profiles) of individual particles. It permits undisturbed views of the most fragile flocculated particles (flocs), or plankton and other material. The name ‘in-line’ derives from the fact that a laser beam passing through water is directly imaged on an imaging sensor (e.g. CCD or CMOS). " - In line holography
