Abstract: A new family of radiation sensors is introduced which do not require anyoptics. The sensors consist of arrays of elementary sub-sensors with naturalcosine-law or similar angular sensitivity supplemented with a signal processingunit that computes optimal statistical estimations of source parameters. Weshow, both theoretically and by computer simulation, that such sensors arecapable of accurate localization and intensity estimation of a given number ofradiation sources and of imaging of a given number of sources in knownpositions. The accuracy is found to be dependent only on the sub-sensors noiselevel, on the number of sub-sensors and on the spacing between radiationsources.
