In complex optical systems conversion of their characteristics, such, as: a magnification, a focal distance, a field of vision etc., without entering of any changes into the circuitry of the instrument, is carried out by different application of nozzles. In view of the fact that they are, a removable part of an optical system, therefore, shan't influence provisions of input and output pupils of the instrument in general. Most often as those nozzles the calculated telescopic systems and continuous or variable increase are used separately. This operation is devoted to the analysis of the pancratique nozzles with the smooth magnification, with a possibility of their application in high-aperture systems.
The article investigates the possibility of using diffractive optical elements on an example of the kinoform in the optical coherence tomography (OCT). The article gives a brief overview of modern methods of research in the OCT, the expediency of development hyperchromatic lenses for spectral OCT systems. The authors made the aberration analysis of diffractive optical element (DOE), conducted a review of its application, and the DOE proposed to use in the example of a kinoform as the main force component of the hyperchromatic lens. In conclusion, the article provides examples of developed hybrid lenses for two spectral ranges, lens transmittance analysis and the assessment of their adaptability.
The article presents the research result and the optical design of long-focus telephoto lens for photo shooting by the academician Maksutov’s scheme. It shows a review of lenses for photo shooting on the market today, and also an analysis of the correctional possibilities which is based on the scheme is presented; studied long-focus telephoto lens is compared with its closest analog, the calculation of a new telephoto lens with higher image quality is made on the basis of that comparison.
Inter-satellite link (ISL) is a system of several satellites, which encircle the earth and spaced at a fixed distance from each other - of about 3000 kilometers. The optical-mechanical module (MOM) for the ISL is designed to transmit data over long distances in a small range of angles.
The article is devoted to problems of research and development of hyper - chromatic lenses for optical coherence tomography. The article discusses the possibility of developing hyper - chromatic lenses for a given spectral range made of glasses only. It is proposed to use the kinoform as the main power element of lens. There are shown the results of the analysis of the aberration properties of kinoform, as well as conclusions about the impossibility of its use as a single component of hyper - chromatic lens. There are shown the formulas for calculating the overall characteristics of a kinoform. The study also considered the method of calculation of hybrid lens consisting of a kinoform and lens parts. The article gives examples of hybrid lenses developed with the main characteristics and overall quality characteristics.
Improving of the autocollimating systems characteristics is a line of optical engineering development. It is associated
with study of initial errors and ways of their reduction. Study is devoted to the influence of tetrahedral reflectors
properties (errors of dihedral angles) on the characteristics (accuracy et al) of autocollimating and autoreflection opticalelectronic
systems for positioning control. The MATLAB mathematical model of tetrahedral reflector was developed for
these purposes; results of simulation were compared with Zemax simulation. It is important to notice that the process of
image formation is quite complex, it explains by superposition of six reflected and deflected beams. Because of the
dihedral angle errors six compound images separate or overlap; that causes the redistribution of energy and image
becomes complicated for processing. The aim is to study the influence of reflector properties on position of the image
energy center, because it defines the measurement error. The influence of the tetrahedral reflector properties on system's
characteristics is shown by example of shift control system based on autoreflection scheme.
