Hyperspectral Non Destructive Detection of Cracks

Project period: 11/2015 - 09/2017

Stream Technologies and DT Square are building a new non-destructive test for detecting fine cracks in hard materials such as ceramic. Stream has patented technology for hyperspectral imaging and DT Square has years of experience in industrial measurements and algorithm development. The solution involves a series of multi-coloured LED lights and a hyperspectral camera. Surface defects such as cracks will reflect light differently than intact surface and will be captured and processed in real-time. An operator will be shown visual cues, such as a coloured overlay on a video monitor, allowing an action-decision. Industries affected include aerospace, medical, resource/oil, automotive, etc.
