【Abstract】 The paper describes the definition and the calculation methods of the wave band detectivity D *Δλ. Considering the space application of 8-14 μm infrared detector, the article discusses the relationships between the wave band detectivity D*Δλ and the temperature T of the radiation sources. The conclusion demonstrates it is advantageous making the wave band detectivity D*Δλ (and the wave band response) instead of the peak wavelength detectivity D*Δλ(and the peak response) . At last, the measurement and the calculation methods of the wave band detectivity D*Δλ are introduced, too.更多还原
