Abstract:
1. A method of establishing position dependent focal laws for the ultrasonic inspection of a specimen with complex geometry, said method being performed by a computing device and comprising: (a) creating a computer model fully describing the geometry of the specimen; (b) partitioning said model into distinct first and second regions (c) determining a first set of focal laws for use with said first region, said first set of focal laws approximately accommodating said distinct irregular geometric characteristics of said sub-regions in said first region (d) determining a second set of focal laws for use with said second region, said second set of focal laws approximately accommodating said distinct irregular geometric characteristics of said sub-regions in said second region (e) associating each position of a scanner with at least one of said first or second regions and storing the association in memory; and (f) positioning said scanner to a portion of the specimen within said first region and applying said set of focal laws associated with said first region (g) repositioning said scanner to a portion the specimen within said second region and applying said second set of focal laws associated with said second region.
