Laser speckle patterns were used for characterization of skin topography (DermaSpec, 13N13841). A set of parameters were obtained for skin surface characterization.Preliminary data has already shown differences between skin tumor and healthy skin are

The lens-free inline holographic microscopy will be extended by the use of microfluidic chips with a total thickness up to 5.5 mm. The microfluidic chip contains an integrated pinhole mask and additional reference markers inside the channel. Blood ce

We present the digital inline holographic microscopy for blood cell counting. The microscope unit contains a pinhole chip for illumination, a micro-fluidic chip, and a CMOS-chip for detection. The design is adapted and tested for blood cell diagnosti

For lensless digital in-line holographic microscopy a new state-of-the-art spatial resolution corresponding to an NA of 0.8 is shown based on the tile superposition propagation. The result is proved using a common glass sample carrier with a refracti

For applications in the domain of digital holographic microscopy, we present a fast algorithm to propagate scalar wave fields from a small source area to an extended, parallel target area of coarser sampling pitch, using the first Rayleigh-Sommerfeld

In lensless digital in-line holographic microscopy, currently applied fast reconstruction techniques use approximations limiting the usable NA for optical resolution. The computational effort for an exact scalar reconstruction with straightforward al

Holographic micro-imaging setups commonly use high coherent laser light sources, which cause coherent noise. It is shown how a partially coherent illumination suppresses the coherent noise and optimizes the imaging quality.

A self-calibration technique for lensless compact chip-microscopes based on inline holography with pinhole illumination is presented. The pinhole illumination wave acts as reference and is needed for the reconstruction process. This reference wave is
