| Abstract | Here is presented a concept of a compact optical Fourier-transform spectrometer (FT) working in a wide spectral range in real time and containing no moving parts. Most of the existing FT spectrometers consist of optics to create an image of the interference pattern on the detector plane. The concept presented here does not require these optical components because interferometer consists of multi channel Fabry Perot interferometer with stepped or gradually changing thickness attached directly to the detector array or detector matrix. As a result this allows complete integration of the interferometer with the detector together to one of the main spectrometer units. Two types of these spectrometers were simulated and experimentally tested. The first type with the wedge interferometer is suitable for analysis of optical radiation with partially coherent radiation and exhibits higher resolution and response to coherent radiation and lower response for non coherent radiation. Second one with cylindrically shaped interferometer suitable for spectroscopy with white sources shows lower spectral resolution. Both types of the spectrometers were tested from 0.6 mum to 2 mum with a 256 pixels extended InGaAs array detector. |

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.
