Abstract
The heat flux q(w)(t) evaluated by using data on isotherms in the coor dinate-time plane is considered in this work. The possibility of optic al heat flux sensor creation is discussed. The isotherms are recorded by using temperature indicators. The mathematical statement of this pr oblem is formulated as an optimization problem. It is solved with grad ient methods and in each iteration the heat equation is solved by the finite-difference method. The results of the numerical experiments are presented.
