Abstract
A passive thermal imaging system, includes a first detection unit, a second detection unit, imaging optics and processing electronics. The first detection unit and second detection unit each include at least one first detector array. The imaging optics are configured to image a first wavelength range of received EMR onto the at least one first detector array, and to image a second wavelength range of the received EMR onto the at least one second detector array. The processing electronics are configured to receive a first detected signal from the at least one first detector array and to determine whether a first detection event has occurred based on the first detected signal, and to receive a second detected signal from the at least one second detector array and to determine whether a second detection event and a third detection event have occurred based on the second detected signal.
