Geometric Solution of Image Degradation by Diffraction in Lensless Sensing and Microscopy
Sanjeev Kumar, Manjunatha Mahadevappa, Pranab Kumar Dutta
This paper proposes a non-computational method of counteracting the effect of image degradation introduced by the diffraction phenomenon in lensless microscopy. All the optical ima…
Lensless in-line holographic microscopy with light source of low spatio-temporal coherence
Sanjeev Kumar, Manjunatha Mahadevappa, Pranab Kumar Dutta
Lensless microscopy with coherent or partially coherent light sources is a well known imaging technique, commonly referred as digital in-line holographic microscopy. In the establi…
Photonic crystal fiber for high resolution lensless in-line holographic microscopy
Sanjeev Kumar, Manjunatha Mahadevappa, Pranab K. Dutta
We propose to use high numerical aperture single mode optical fibers like photonic crystal fiber for lensless in-line holographic microscopy. Highly divergent beam helps to overcom…
