Anomaly Detection In Additively Manufactured Parts Using Laser Doppler Vibrometery
- Lawrence Livermore National Lab. (LLNL), Livermore, CA (United States)
Additively manufactured parts are susceptible to non-uniform structure caused by the unique manufacturing process. This can lead to structural weakness or catastrophic failure. Using laser Doppler vibrometry and frequency response analysis, non-contact detection of anomalies in additively manufactured parts may be possible. Preliminary tests show promise for small scale detection, but more future work is necessary.
