摘要

A technique adapted from the echo-location method used by bats and used to improve radar performance could prove to be an effective way of detecting dangerous defects in aircraft, racing cars and spacecraft.An Anglo-Indian project will analyse the efficiency of a thermography method called Frequency Modulated Thermal Wave Imaging. Thermography involves examining heat as it flows across an inspected part. If a crack that could lead to failure is present, it will trap heat and this will show up on infrared camera scans.
