WebMar 1, 2006 · A two-beam photo-carrier radiometry (PCR) technique of semiconductors has been developed. The technique operates on the superposition of superband-gap and subband-gap laser beams which results in the cross-modulation of the backscattered subband-gap laser intensity by the harmonically varying free-carrier-wave density … WebInfrared photocarrier radiometry (PCR) has not been widely used to characterize metals, especially steels. In the case of metals such as carbon steel, thermal and electrical properties depend on the electron excitation movement. PCR images were obtained through thermal changes analyses of different carbon content steels.
