Non-destructive testing of carbon reinforced plastics by means of phase retrieval

, 2012
In this work, the SLM-based phase retrieval system will be used to inspect carbon reinforced plastics samples (CFRP) under applying a thermal load. For this purpose, the system is used to capture a sequence of 8 spatially separated recording planes ...
