Abstract :
It was demonstrated that all thermo-emission materials possess considerable emission heterogeneity; therefore the current take-off shall be described accordingly. An original current take-off equation was suggested with account of emission heterogeneity. The equation structurally represents a linear first kind Fredholm integral equation. It was demonstrated that the inverse problem - emission heterogeneity determination from emission test results - is ill-posed and requires involvement of a priori information for its solution. Good agreement of theoretical and experimental results was demonstrated.
