Roemer J. The concept of Laser Spot Thermography test rig with real-time data processing. The International Journal of Multiphysics. 2020;14(1):31-38 https://doi.org/10.21152/1750-9548.14.1.31Abstract
The paper shows the concept of Laser Spot Thermography test rig with real
time data processing. Laser Spot Thermography is a promising method for
non-destructive testing applications especially, when fully non-contact
procedure is required. Unfortunately, the procedure as of now is hard to
apply, due to technical difficulties related with data processing. Laser
thermography test procedure involves recording of multiple sequences
(even hundreds), which have to be processed and evaluated as a whole.
The industry requires quick and precise results, which is hard to achieve with
the amount of output data from the currently known test procedure. The
paper gives a proposal for improving the laser thermography test procedure
through data parameterization (curve fitting) for infrared sequences. The
data parameterization allows for reduction of output data size, in particular
temporary data storage in RAM. The reduction of data size leads to faster
real time processing.
