Abstract
A new concept has been proposed and developed to overcome some deficiencies of current infrared imaging systems and to improve future surveillance system for search and rescue operations. Based on the focal plane array detector technology and simulating the properties of the human eye, the concept allows surveillance and target acquisition in two fields of view simultaneously. A wide peripheral field of view (60 degress), optimized for sensitivity but of low resolution, is dedicated to search and detection. A narrower field of view (6 degree), which can be steered within the wider field, optimizes the recognition of detected objects means of an improved resolution obtained through the use of a microscanning technique. The high resolution required for the simultaneous display of projection and superposition. This display is well adapted to the human eye and hence mechanical and electronic designs imposed by the mobility of the narrow field within the large one; by the microscanning mechanism and by the calibration requirements of the focal plane array. The selected solutions are also presented. The limitations of the system in its current state of development are outlined and plans for future improvements are elaborated.
