The influence of obtaining and heat treatment conditions on the structure of As₂S₃-SbSI system

Autor: Rubish, V.M., Bih, L., Mykaylo, O.A., Gorina, O.V., Maryan, V.M., Gasinets, S.M., Solomon, A.M., Lazor, P., Kostyukevych, S.O.

(As₂S₃)₁₀₀₋x(SbSI)x (x = 80 and 90) glasses were prepared by cooling homogenized melts from 720…750 K in cold water. Their structure and structural changes under heat treatment of glasses are confirmed by studies of micro-Raman scatteri

Perspectives for using technology of laser thermolithography

Autor: Kryuchyn, A.A., Lapchuk, A.S., Bryts’kyi, A.I., Kostyukevych, S.O.

Analyzed in this work are the requirements to an optical system for laser thermolithographic recording. It has been shown that possibilities of this type recording with decreasing the registered element sizes can be realized only when using special m

The new approach to identification of film reflecting holographic marks

Autor: Kostyukevych, S.O., Muravsky, L.I., Fitio, V.M., Voronyak, T.I., Shepeliavyi, P.E., Kostyukevych, K.V., Moskalenko, N.L., Pogoda, V.I.

The new approach for creation of film reflecting holographic marks for optical security is proposed. Such marks are replicas of a reflecting master hologram recorded on a chalcogenide glass layer. To receive the master hologram, the joint power spect
