Abstract | Summary form only given. Recently various time-gating techniques have been applied to imaging through random scattering media, in particular animal tissues. Because scattered photons travel longer paths, by time-gating one can reject scattered photons, thereby reducing interferences from scattering. An interesting question about time-gated imaging through random scattering media is the limit of spatial resolution. Because the gating width cannot be infinitesimally small, it is not clear how parameters such as the gating width and the medium thickness determine the resolution or, furthermore, in what way the image degrades as the object size becomes smaller than the resolution limit. To answer these questions, we analyze spatial distributions of time-gated photons, which have traveled through random scattering media, by a method at random-phase path integration and from the distributions we derive the resolution limit. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
