Photoacoustic FT-IR depth imaging of polymeric surfaces : overcoming IR diffraction limits
It is well established that the photoacoustic effect based on absorption of electromagnetic radiation into thermal waves allows surface depth profiling. However, limited knowledge exists concerning its spatial resolution. The spiral-stepwise (SSW) approach combined with phase rotational analysis is...
