摘要：An apparatus for performing in-line lens-free digital holography of an object, comprising: • - a single point light source (2) adapted for emitting coherent light; • - an image sensing device (5) adapted and arranged for recording interference patterns wherein • - the point light source comprises a broad wavelength spectrum light source and a pinhole structure, • - the image sensing device is adapted for receiving and recording, at the same moment in time, a plurality of interference patterns by a respective plurality of disjoint subsets of pixels (I, II, III, IV); • - the image sensing device comprises for each of the disjoint subsets of pixels, a respective narrow band wavelength filter positioned above each of the pixels of the disjoint subset of pixels, wherein a wavelength range of each narrow band wavelength filter falls within the broad wavelength spectrum of the point light source, these wavelength ranges of the narrow band wavelength filters being non-overlapping;
