6.9  Lockin 

 
General 

Lock-in technique is commonly used in thermography to improve the sensitivity of the camera 
and extract from the thermal signal the thermal effects correlated to an external excitation in 
the material under evaluation. 

 

 

 

 

 

The X8400sc camera features a lock-in signal input BNC connector on the back panel of the 
camera (ref 7 on Figure 2: Camera back panel description). 

 
 

 

The  value  of  the  signal  is  digitalized  during  the  integration  of  the  infrared  image  and 
embedded  within  it.  It  is  then  recorded  by  ResearchIR  Max  and  stored  in  the  sequence  file 
image headers. 

 
 

 

Files recorded with ResearchIR Max can then be exploited with FLIR Thesa software. Please 
contact your FLIR representative for further information.
