The ARL is currently performing work on the effects of low velocity impact damage on subsequent damage levels in opaque ceramics caused by higher velocity threats. Microwave frequency (interference) scanning is a relatively new NDE method that has undergone significant basic development and technical advancement over recent years. It has significant advantages in ease of use, one sided inspection, compactness, portability, applicability in varied environments, non-ionizing radiation, and no need for transferring medium between probe and specimen. A series of microwave scans were performed on a set of damaged metal backed ceramic tile modules used in the ARL research using the new technology. Microwave scans of a number of different damaged ceramic tile modules will be shown. The characteristics and quality of the scans will be discussed as well as some comparisons to results from other NDE methods, such as ultrasonic and x-ray digital radiography/computed tomography scans or images.
