| Abstract | A new non-contact method for measuring both surface and internal temperature distributions of heated materials is presented. A laser-ultrasound technique that enables non-contact ultrasonic pulse-echo measurements is employed in this work. An effective inverse method is developed to determine the temperature distributions quantitatively. To demonstrate the practicability of the developed method, some experiments with aluminum and steel plates heated up to 150 °C are carried out. Using the laser-ultrasound, surface acoustic waves and longitudinal waves of heated plates are measured to estimate the surface and internal temperature distributions, respectively. It is verified that the ultrasonically determined results almost agree with those measured using an infrared radiation camera or thermocouples. Thus, the ultrasonic method is believed to be effective in the in-situ or in-process monitoring of temperature distributions of materials being processed at high temperatures. |

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.
