Dobrovolsky Y. Primary transducers to measure the energy characteristics of the optical radiation. Manuscript

The object of research - the optical radiation detection processes and converting it to energy units. Research subject - primary converters and measuring instruments for the study of energy characteristics of optical radiation. The goal - the creation of an integrated theory and practice of development of primary converters for measuring power characteristics of optical radiation in the UV, V, near-infrared regions of the spectrum, as well as the laser radiation in the range of 0.2 to 2 m. The theoretical analysis is based on the provisions of solid state physics, microphotoelectronics, the theory of errors. In the experiments, the use of optical, electrical and thermal measurement methods, precision machinery, computer equipment. Basic theoretical and practical results are to develop the theory of photocurrent generation of photodiodes on the basis of germanium, silicon, gallium phosphide, zinc selenide; mathematical model of the mechanical vibrations of the Peltier thermoelectric modules; Mathematical models of two and three spectral photodetectors. The development of scientific and technological bases for the creation of photodiodes with high sensitivity in the shortwave UV region of the spectrum on the basis of silicon and barrier structures of Ni-GaP-SnO2-In and Ni-ZnSe(Te)-In; a number of p-i-n photodiode based on high-resistivity silicon p-type conductivity and minimized dark current, high sensitivity and resistance to background radiation; mathematical models of photodiodes sensitivity assessment based on epitaxial structures; thermally stabilized photodiodes (including avalanche) based single crystal and epitaxial germanium with minimized dark current and increased sensitivity at a wavelength of 1.5 m.
