Termo-electric effect cоncept in inclination-condensed film of policrystal materials obtained by vacuum-thermal vaporization and condensation on the isolated heat conduction substrate is developed. The models for analysis of the peculiarities thermal-e.m.f. (thermal electrical moving force) in anisotropic medium, the estimation of sensitivity to continuos radiation, shape definition of outer signаl from short-impulse radiation and the role of surface film comb is proposed. Main parameters of created and investigated inclination-texture thermo-electrical converters of different types are presented: roud, snaked and spiral sensitive-measuring input-converter thermo-electrical elements. The inclination-texture thermo-electrical converters are analogs of the anisotropic monocrystal. It enabled to amlify the natural anisotropy and to create artibicial "anisotropy" of thermal-e.m.f. which extended the choice of initial materials including high-temperature and isotropic materials for increasing of laser ray stength. The improvement of the sensitive-measuring input-converter thermo-electrical elements is accompanied not by new materials attracting and not by the transition to more complex materials and/or technology but by returning to known simpler materials both on composition and on technology.
