Quantitative Infrared Thermography (QIRT) conference is a biannual international conference, in which Infrared Thermography (IRT) specialists from industry and academia discuss and present their current interests and novel developments. Since 1992, QIRT conferences have been held in Paris (1992), Sorrento (1994), Stuttgart (1996), Łódź (1998), Reims (2000), Dubrovnik (2002), Brussels (2004), Padova (2006), Krakow (2008), Quebec City (2010), Naples (2012), Bordeaux (2014), Gdańsk (2016), and Berlin (2018).

All conference proceedings are available through the QIRT Conference Open Archives at www.qirt.org.
