Thermographic techniques include:• PassiveThermography:SimplyusingIRcameras tocheckforhotspots

• Photo-ThermalCamera:Laser-generatedheat stripepropagatesmoreslowlyacrosscracks. Timesequenceprocessedimagescanidentify thesecracksaswellorbetterthanPTremotely (toseveralfeetandwithnochemicals)

• FlashThermography(inductive,radiant, conductive):Transientheatdissipationrates canindicatewallthinningfromanumberof damagemechanisms

• Vibrothermography:Ultrasonicenergycan causecracksto“light-up”fromfrictionbetween cracksurfaces

Features and Benefits• Remote:IRcameracanbelocatedremotely (uptoseveralfeet)

• NoChemicals:UnlikePTandMTsurfacetests, thermographictechniquesgenerallydonotrequire anycoatingsorchemicals

• IRimagesareanalogoustovisualimages,so anomalylocationsandorientationsareeasily relatedtothecomponentgeometry
