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). WebbIn the holographic dual we re-visit well-known solutions for a probe D3-brane that describe this theory with a symmetric-representation Wilson line “impurity”. We present evidence that the adjoint scalar screens the Wilson line, by showing that quasi-bound states form at the impurity, producing U(1)-impurity scattering phase shifts and …
