ABSTRACT:
A focal plane array (30) for a thermal imaging system (20). The focal plane array (30) may include a number of thermal sensitive elements (42) formed by a first series of slots (78) and a second series of slots (80). The thermal sensors (40) may be bounded by a border (41). The thermal sensors (40) may provide a sensor signal output representative of thermal radiation incident to the focal plane array (30). The first series of slots (78) may include a leading first slot (82) and a trailing first slot (84). Additionally, the first series of slots (78) may include a number of substantially parallel first slots therebetween. The second series of slots (80) may include a leading second slot (86) in a trailing second slot (88). The second series of slots (80) may also include a number of substantially parallel second slots therebetween. One of the first slots may extend beyond the leading second slot (86). Additionally, one of the first slots may extend beyond the trailing second slot (88). A common electrode (36) may be coupled to the thermal sensitive elements (42) and to the border (41). An optical coating (34) sensitive to infrared radiation may be provided in communication with the common electrode (36).
