Abstract A new family of radiation sensors is introduced that does not require any optics. These sensors consist of array of bare radiation detectors whose angular sensitivity is determined solely by their surface absorption. This array is supplemented with a signal processing unit that uses the detector outputs to compute optimal statistical estimates of the intensities and coordinates of radiation sources. Such sensors are capable of accurate localization and intensity estimation of a given number of radiation sources and of image forming when assuming of a given number of sources in known positions. The estimation accuracy is found to depend on the detectors' noise level, on the number of detectors and on spacing between radiation sources. Advantages and limitations of proposed opticsless sensors are discussed. In addition a hypothesis is advanced that the operational principle of the sensors can shed a light on possible mechanisms of cutaneous vision in Nature and on evolution of vision.

About National Digital Library of India (NDLI)
NDLI logo

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.
