|Abstract||Introduction Fiber optic sensors for temperature and pressure using the optical system based on the Mach-Zehnder interferometer have been proposed by several workers. In order to eliminate the e#ect of noise in the reference fiber of two single-mode fibers, several methods which use only one fiber have been proposed , . However, in these methods the special birefringent fiber is required. Instead of using such special fibers, a sensor which is constructed using a conventional multimode optical fiber has been proposed by the author. In this proposed method, two modes in a multimode fiber are excited by the mode-division multiplex  using a computer-generated hologram . In the previous report , a temperature change was measured by the interference between two modes. However, the theoretical analysis of the interference was inadequate in the report. In this letter, we intend to present a theoretical analysis to describe the interference phenomena by a conventio|

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.
