| Abstract | In this paper, we studied image processing techniques for the fast measurement of wavefront with high measuring resolution. We investigated the relation between the measurement resolution and the measurement speed by using several measuring techniques of wavefront. And then, we decided on optimum conditions of signal processors for a wavefront measuring device using a Shack-Hartmann sensor and proposed an estimated weighting factor to rapidly calculate wavefront with a high measuring resolution. We designed an adaptive optics system using a Shack-Hartmann sensor to measure and correct wavefront distortions of a laser beam. We tested several wavefront measuring techniques including our proposed algorithm. From the experimental results, the proposed signal processing techniques provided fast measurement results with high measuring resolution. |

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.
