Introduction
Namaskaram,I am Manisha,currently a research scholar at the Laboratory of Information Photonics and Optical Metrology, in the department of Physics, Indian Institute of Technology (Banaras Hindu University) Varanasi. My work is mainly focused on imaging through random media.

Article
Imaging through random scatterer is a challenging problem due to spatial scrambling of the light wavefront and formation of the speckle pattern. Here, we present a new experimental configuration in holography with a two-point intensity correlation to reconstruct the orthogonal polarization modes from a single shot measurement of the speckle pattern...
Conference Paper
We present a ghost diffraction scheme with spatially fluctuating fields. This is implemented by replacing ensemble average with spatial average rather than temporal average as used in conventional ghost diffraction schemes.
Article
We report a new method to reconstruct a two-dimensional object in Ghost diffraction scheme using a spatial statistical optics approach. This is implemented by using a static diffuser rather than a pseudo thermal light source generated with a rotating diffuser as used in conventional ghost imaging systems. The experimental implementation makes use o...
Preprint
The wavefront is scrambled when coherent light propagates through a random scattering medium and which makes direct use of the conventional optical methods ineffective. In this paper, we propose and demonstrate a structured light illumination for imaging through an opaque scattering layer. Proposed technique is reference free and capable to recover...

We report the reconstruction of a transparency image in Ghost diffraction scheme using a statistical optics approach. This is implemented by using a static diffuser rather than a pseudo thermal light source with a rotating diffuser. The experimental implementation makes use of spatial ergodicity and spatial stationarity for spatially distributed ra...
Conference Paper
Full-text available
Phase of an object plays a crucial role in retrieving the complete information. Digital in-line holography is a simple and effective technique to retrieve the phase information and 3D features of object. However the twin image formation limits the total information that can be obtained using in-line holography. Here in this paper, we show how deep...

Coherence function is a complex quantity and follows wave equation similar to the optical field. Utilizing this analogy, wepropose a new method to craft the correlation structure of the light. This is realized by considering the interference of coherence waves due specially positioned incoherent sources in the Fourier space. Basic principle of the...
