What is “light bar testing”?

A photo of the Parker Solar Probe was captioned as follows:




In the Astrotech processing facility in Titusville, Florida, near NASA's Kennedy Space Center, on Tuesday, June 5, 2018, technicians and engineers perform light bar testing on NASA's Parker Solar Probe.




I wasn't able to find any references to this sort of process in NASA literature - even Armadillo's Ben Brockert was perplexed.



Is this something specific to the Parker probe, or a standard NDT process?

          This test was performed to ensure that the 44 series of solar cells (or "strings") were still connected. After the acoustic and vibration testing, there was a chance that some of the electrical connections could have been broken, so the test used a bar of purple lasers (a "light bar") to verify that the strings were still functioning properly. A laser bar was used because it could test a single string at a time. Purple lasers happened to be on hand, and the solar cells function efficiently at that wavelength. Infrared lasers were also used.

            I would have used a bunch of purple lensed LEDs taped to a stick and just held it a few cm away, but then again I don't work for NASA. Sharks with lasers!
