文摘

Heat sources are reconstructed from noisy temperature fields using a GAD filter. The GAD filter is optimized using synthetic temperature fields corrupted by noise. Rectangular heat source concentrations are considered in two-dimensional plates. Results are compared with those obtained using a Gaussian derivative filter. Experimental fields on plates heated by electric patches are successfully processed.
