Abstract :
An acoustic micro-imaging (AMI) technique for the evaluation of microelectronic packages and populated circuit boards is proposed. The technique is based on the concepts of sparse signal representation in overcomplete time-frequency dictionaries. The experimental results demonstrate its superior ability to conventional AMI techniques.
