Paper Abstract

Modulation lifetime inspections a new kind measurement mechanism in Frequency Domain. A CW tunable Xe lamp is used as a pumping source, which is modulated first and excites sample sequentially. The lifetime could be obtained by analyzing its demodulation (m) and phase shift ((phi) ). Because the excitation light power density is only about 1W/s, the lifetime of delicacy material could be inspected beautifully, accurately and nondestructively. Thus it is undoubted that Modulation Inspection is the best method for lifetime measurement of delicacy material.
