The results of the elaboration, testing, and application 
(in bench studies) of fiber sensors of linear ablation of a heat shield 
material are presented. The measuring technique and the structural 
arrangement of the sensors designed for products of the research and 
production association (RPA) "Energiya" and the design office "Novator" 
(Russia) have been described. Methods for manufacturing a ceramic 
tip equipped with fiber ablation sensors have been developed.
