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). WebbAbstract. Deep neural network (DNN) has been applied in many fields. Here, we use DNN to separate interference terms in in-line hologram and reconstruct the pure phase …

WebbNumerical hologram reconstruction was initiated by Yarosl avskii et al [11–13] at the early 1970s. They sampled optically enlarged parts of in-line and Fourier holograms recorded on a photographic plate. These digitized ‘conventional’ holograms were reconstructed numerically. Onural and Scott [14–16] improved the reconstruction

Webb20 nov. 2024 · Phase retrieval and the twin-image problem in digital in-line holographic microscopy can be resolved by iterative reconstruction routines. However, recovering the phase properties of an object in a hologram requires an object plane to be chosen correctly for reconstruction. In this work, we present … WebbHolograms and reconstructions with good resolution were achieved. However, they needed acquisition of over 1000 shots to get enough photons. These different works and their conclusions point out that digital in-line holography using high harmonics is possible. More important they showed that there is room for improvements of the method and …
