  • Abstract
    Surface-wave holographic techniques can be used to detect the presence of small defects. The detection limit is usually determined not by signal to noise considerations, but rather by the presence of spurious background signals, such as bulk waves. The letter describes a technique for eliminating this background, and demonstrates the improvement in the detection limit.
