Developing new criteria of efficiency for road LED luminaires
Engineering Education # 07, July 2013
DOI: 10.7463/0713.0579034
This article is important because of both wide assortment of road LED luminaires on the Russian market and a large set of their technical parameters and characteristics. New criteria of energy efficiency for road LED luminaires were elaborated and scientifically corroborated. These criteria of energy efficiency of LED luminaires allow one to prevent a wrong choice of a luminaire and to identify the most suitable model. Appropriateness of criteria introduction was confirmed by the example of choosing the most energy-efficient LED luminaires for the selected scheme of road illumination. The introduced criteria allow experts in road and street illumination to choose the most suitable luminaire from all available ones on the LED luminaire market in order to replace the incandescent luminaires for the purpose of energy-saving.

Study of the influence of angular aberrations of the optical-electronic coordinator lens on the quality of measuring the mutual angular misalignment of the laser beams
Engineering Education # 11, November 2012
DOI: 10.7463/1112.0479575
This article considers a self-alignment system (SAS) designed to measure the mutual angular position of laser beams while designing, operating and adjusting high-precision laser optical-electronic systems (OES). A method of measuring angular misalignment of optical axes of receiving and transmitting system channels with the use of various algorithms of digital signal processing is proposed. Measurement error is analyzed; technique for reducing this error by means of optimization of lens optical system, which is used to perform those measurements, is proposed

Surface roughness measurement methods analysis and experimental study of diffusive scattering reflectometry-based method
# 06, June 2012
A review of the most promising methods for measuring the roughness of a nanometer level showed that the most promising method for measuring the standard deviation of the optical surface roughness is a method of dynamic interferometry. An experimental study of the effect of diffuse scattering on the intensity of radiation reflected in the specular direction, for surfaces with parameter Rq, equal to 5 nm, 10 nm and 50 nm. Found that diffuse scattering leads to intensity fluctuations and the contribution of this scattering in the specular reflected radiation is 0.25% for Rq = 10 nm.active media

Engineering Education # 10, October 2011
The article considers a system of automatic adjustment of high-precision laser devices that are using a powerful mainlaser radiation. This system performs alignment of optical axes of receiving and transmitting channels with additional marker laser. Considered problems arising due to the spread of high-power infrared operating laser close to receiving channel, designed for visible light. A method for study of the influence of diffraction on parameters of radiation of the mainlaser is proposed. The technique of study of influence of thermal blooming on the parameters of radiation of the mainlaser on the basis of approximation of the thin lens is developed.
