WebFlame photometric detector (FPD) theory of operation A FPD measures trace sulfur compounds. It uses the reactions of sulfur components in a hydrogen rich flame as a source for analytical detection. The source of the FPD’s signal is derived from the light produced by an excited molecule created in the flame’s combustion. WebThe presented algorithm can tolerate up to N − 3 missing points, even tough the more points are missing the higher the chance of a wrong detection is. The complexity of the algorithm is O (K 3 N), where K is the number of image features kept after the photometric test and N is the number of object points.
