![]() The laser light source has a wavelength of 405 nm. ![]() The 3D structure of the object from the 2D hologram is reconstructed using a numerical algorithm (Kirchhoff-Helmholtz transform). The interference pattern produced is displayed as a hologram stored as a digital image. The wave illuminates the object and forms a geometrically magnified diffraction pattern on a charged couple device (CCD) screen. A laser is directed into a pinhole from which a spherical wave emanates. ![]() It uses the principle of digital inline holography (DIH) to produce enlarged images of an object and its 3D structure. It outputs up to 22 images per second in real-time. Plankton net described as 1-metre ring net designed with single circular (ring) mouth piece with measurements: mouth diameter (metre)=1 with opening area (square metre)=0.8 with total filtering net length (metre)=not specified with filtering net shape conical with additional features: can be used for qualitative sampling or the capture of live animals or quantitative sampling if used with flowmeter with mesh size (millimetre)=0.333 as a standard but may vary and equipped with NO closing mechanism.Ĥ-Deep Inwater Imaging HoloSea S7 submersible holographic microscopeĪ submersible holographic microscope for use in water profiling and monitoring applications, as well as particle, phytoplankton and zooplankton imaging for counts and morphological analysis.
