| Abstract | This paper proposes measurements of a two-dimensional inclination angle of a mirror, and its distance to the mirror, using four infrared LEDs that are located around a position sensitive detector (PSD). The light of each LED is reflected by a mirror and focused on the two-dimensional PSD through a lens. This method has many advantages. The mirror's inclination angle is able to be measured by two LEDs at opposed positions without having to depend on information about the distance to the mirror. Since the LEDs act as point sources of light, it is unnecessary to have to adjust the axis of light. This device has a simple structure, and the light itself is safe since the source is an LED, not a laser light. It was confirmed that the measurement accuracy of the inclination angle was less than 0.5 degrees in a wide range of −10 to 10 degrees and the result was sufficiently satisfied. This equipment can also measure the distance between the sensor and the mirror with an accuracy of 5 percent. |

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.
