Chirp coded ultrasonic pulses used for scanning acoustic microscopy
Fil(er) med begrenset tilgang er under embargo til 2019-11-02
In the present study, chirp coded pulses are investigated with respect to high frequency imaging. These pulses were used drive broadband polymer transducers assembled from an adhesive-free layer-be-layer deposition method. The image quality obtained from using a long chirp coded pulse was compared with images generated from shorter pulses. This includes the Ricker wavelet and the square pulse most commonly used for scanning acoustic microscopes.
