© 1991 SPIE. All rights reserved. The use of step-scan Fourier transform infrared (FT-IR) spectroscopy combined with photoacoustic (PA) detection is used to depth profile laminated polymeric materials. Depth profiling can be performed using a combination of the modulation frequency dependence and phase lag of the PA signal.
