Sven-Åke Ljungberg passed away on 14 June after a battle with cancer.
Ljungberg was instrumental in the early development of SPIE Defense, Security, and Sensing (DSS), and the building of the AeroSense conference. He authored and submitted 15 papers starting with DSS 1989-2002, and served as a session chair 13 times, from 1992-2004.
"On behalf of SPIE, I send our heart-felt condolences on the loss of Sven-Åke Ljungberg, who was an important long-standing member and pioneer of the Thermosense Working Group," said DSS event manager Diane Cline.
Along with being a long-time contributor for DSS and and the Thermosense community, Ljungberg had been also a long-standing, valued member of SPIE. He retired as senior research associate at Högskolan i Gävle in Sweden.
