A novel homomorphic signal processing method is presented for accurate thickness measurement of thin layers. The method consists in taking the envelope of the inverse Fourier transform of a corrected logarithmic derivative of the energy spectrum (ES) of the measured signal. Simulations show excellent agreement between estimated and actual values. The method is validated by in vitro experiments at 10 MHz on Teflon(R) films, where thicknesses down to 50-mu-m are recovered, and preliminary in vivo results on arterial wall thickness estimates are presented. |
