Thermal Transient Test Apparatus
An apparatus for evaluating the thermal transient behavior of an electroexplosive device is described. The thermal response provides nondestructive testing insight with respect to device design and behavior. Abnormal responses may be indicative of imminent failure and the apparatus provides a rapid evaluation method for quality control.
Exponential-like responses analysis method
An exponential-like responses analysis method is presented. The method enables one: 1) to evaluate the similarity of a curve to the ideal exponential characteristic; 2) to find the most appropriate final value of a curve; and 3) to find the value of Τ giving the best approximation between the analyzed curve and the ideal exponential one.RésuméOn présente une méthode d'analyse des réponses exponentielles. La méthode permet: 1) d'évaluer la similitude d'une courbe à la caractéristique exponentielle idéale, 2) de trouver la valeur finale la plus appropriée d'une courbe, 3) de trouver la valeur Τ qui donne la meilleure approximation entre la courbe analysée et l'exponentielle idéale.ZusammenfassungEs wird eine Analysenmethode für exponentiell-Ähnliche Antworten beschrieben. Die Methode ermöglicht 1) die Ermittlung der Ähnlichkeit einer Kurve mit dem Idealen exponentiellen Charakter, 2) Erforschung des geeigneten Endwertes einer Kurve und 3) Auffindung des Wertes welcher die beste Approximation der analysierten Kurve zur idealen exponentiellen ermöglicht.РЕжУМЕпРЕДстАВлЕН МЕтОД Ёк спОНЕНцИАльНО-пОДОБ НОгО АНАлИжА ОтклИкА.

17 &mgr;m pixel 640 x 480 microbolometer FPA development at BAE Systems
BAE Systems has developed an advanced 640 x 480 focal plane array (FPA) with a 17 &mgr;m pixel pitch. Sensitivity of ≤ 50 mK was demonstrated and the FPAs were used in imaging demonstrations. Successful scaling of BAE Systems' patented single contact per pixel, single-level microbolometer process to 17 &mgr;m pitch provides a path toward next generation microbolometer imaging systems.
