Historical NDT Imaging- CRT

early CRT photos of Honeycomb panels

For the first time on the internet, these historical images of various scans were made of brazed titanium test panels. 7-7a and 7-7b shown at different intensities. The uneven pattern imaging the honeycomb I believe was due to a variety of possible variables in the inspection process- off axis scanning, internal excessive braze material or alternative imaging methods. These were produced in 1956, and no specific notations were available from the research lab.
