What is this page?
This page lists the scientific contributions of an author, who either does not have a ResearchGate profile, or has not yet added these contributions to their profile.
It was automatically created by ResearchGate to create a record of this author's body of work. We create such pages to advance our goal of creating and maintaining the most comprehensive scientific repository possible. In doing so, we process publicly available (personal) data relating to the author as a member of the scientific community.
If you're a ResearchGate member, you can follow this page to keep up with this author's work.
If you are this author, and you don't want us to display this page anymore, please let us know.

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...
The coherence holography offers an unconventional way to reconstruct the hologram where an incoherent light illumination is used for reconstruction purposes, and object encoded into the hologram is reconstructed as the distribution of the complex coherence function. Measurement of the coherence function usually requires an interferometric setup and...

In this paper, we demonstrate a digital micromirror device (DMD) based optical microscopic apparatus for quantitative differential phase contrast (qDIC) imaging, coherent structured illumination microscopy (SIM), and dual-modality (scattering/fluorescent) imaging. For both the qDIC imaging and the coherent SIM, two sets of fringe patterns with orth...

... Learning based methods have also been used for imaging through random scattering media [16,40,41]. Other important methods for imaging through random scattering media are auxiliary [42] and structured light [43,44] etc. ...

... The resolution is expected to be further improved by continuously reducing the pixel size of the DMD (see Texas Instruments Products, TI), increasing the magnification of the projection objective, and shortening the wavelength of the ultrafast laser. In DMD-PL systems, the laser beam collimated with a flat-topped energy distribution is incident on the DMD at a fixed azimuth and incident angle [14], and the output beam comprises a lot of diffraction orders with the discrete angles due to the grid effect [15,16]. The optical objective lens receives one or several diffraction orders as object information for exposure. ...
