Features Of Application Of Mobile Laser Strainmeter In Winter Conditions The exploration technologies of Arctic resources require the results of fundamental studies dedicated to the structure and composition of the sea crust of both shelf and deep-water ice-covered Arctic waters. This article deals with the features of using a surface-type mobile laser strainmeter for solving similar problems. The results of an experiment for determining the speed characteristics of waves generated with a low-frequency hydroacoustic radiator that creates harmonic and complex phase-manipulated signals in water are described.

Measuring Method Of Relief-Frequency Response Of Laser Locators In The Relief Scanning The concept of "relief-frequency response" has been introduced, representing a laser scanner as a filter of spatial frequencies when probing the surface relief. A method for measuring the laser locator relief-frequency response has been proposed using test objects in the form of a step change in range (a spatial analogue of measuring the transient response). The article describes the installation design to determine the relief-frequency response, the method and the results of measurements.

Determination Of Heterocyclic Molecules Ionization Potential Based On Optical Absorption Spectra Of Electromagnetic Radiation In The Visible And UV Range A physical effect connecting the ionization potentials of oxygen- and nitrogen-containing molecules with the integral autocorrelate characteristic of the absorption spectrum in the visible and UV range 190–760 nm (6.53–1.63 eV) was observed experimentally. The research results can be applied in molecular electronics, photonics, photochemistry and physical chemistry to study electron transfer processes, the band structure characteristics of nanoparticles in condensed matter physics.

Optical Time-Domain Reflectometry Methods For Measurement Of Distribution Of Excess Optical Fiber Length In Fiber-Optic Cable Loose-Tubes The methods of excess fiber length measurement in loose-tube cable using optical time domain reflectometer are considered in this paper. The results of climatic tests for the construction length of a modular optical cable are presented. A method for estimating the excess length of an optical fiber via measurements of the fiber backscattering characteristics with a conventional optical reflectometer is proposed. A comparison of methods for determining the excess length of an optical fiber via estimating the bending loss is performed. The errors of line approximation of experimental curves related to excess fiber length dependency from temperature are used as error criterion. The error estimations of described methods are presented and conditions of their usage are considered.
