Optimized geometry in infrared arrays for remote sensing of forest fires

The array proposed in this paper improves the characteristics of standard infrared arrays for remote sensing, in particular, of those used for incipient forest fires detection. The consequences are of interest mainly in staring non-imaging, large-range, large field of view and low cost-sensors. Furthermore, non-uniformity effects in the focal plane as the azimuth angle increases can be properly minimised. Another important advantage is the field of view and fill factor enlargement, maintaining the optics and connection low-level complexity.
