Tymchik G.S., NguyenQ.A., Kolobrodov V.G. The boundary characteristics of a coherent optical spectrum analyzer

The influence of the component dimensions and parameters of a coherent optical spectrum analyzer on its performance was studied. One of the criteria for evaluating the performance of this instrument are the spatial resolution and the spatial bandwidth product. The purpose of this article is to study the dependence of the limiting characteristics on the changing of the component parameters of the coherent spectrum analyzer. It was considered, that the influence of the Fourier lens aberrations and the geometric dimensions of the CCD sensor on the spectral resolution and spatial bandwidth product in the schema of the analyzer, where the input transparency is located at the front focal plane of the Fourier lens. As the input transparency we used a circular aperture. The expressions, that show the dependence of the limiting characteristics on the size of the system components, were obtained in the case of using matrix sensor of a large resolution. The following example shows that the large size of the sensor allows obtaining the high spatial resolution and the large spatial bandwidth product of the device.
Keywords: coherent spectrum analyzer, spatial resolution, spatial bandwidth product, point spread function.

The structure of the control system of quality of a well-bonded coupling fitting onto high-pressure gas-main pipelines is introduced in the article. The control system consists of information parameters measuring instrument, a calculating instrument for optimal preset parameters values and an analyzer which evaluates discrepancy between measured values and optimal ones and making a decision about the system actions relevant to the given discrepancy elimination. The effect of geometrical pipe parameters, a coupling construction, an under-coupling layer material strength parameters, technological parameters of an under-coupling layer forming on a pipeline strengthening has been analyzed. Furthermore, it has been described the requirements to getting control of a pipeline strengthening efficiency and given the system of interrelated equations for calculating optimal controlled parameters values. The proposed control method allows gaining a maximum pipeline strengthening efficiency using a molten metal for an under-coupling space filling. The represented experiment data have confirmed the increasing a pipeline strength by means of installing couplings proposed construction. A good agreement between experimentally derived data and results of theoretical measurements is shown. Also, the optimal technological parameters of an under-coupling layer forming have been defined and proposed.

The paper deals with the specific nature of assembly processes in instrument-making and considers the current state of development of computer-aided design technology assembly and their suitability for conditions of instrument making production. In addition, we develop the mathematical model of the assembly product in instrument-making taking into account complexity and specificity of the assembly, adjustment and test work. We propose the method of forming the model describing the structure of the assembly product which represents it as a hierarchical system of interconnected structural elements. The proposed model is integrated in the CAD system. It is informative and suitable for the process of automated assembly design. Relying on the proposed method describing the product structure we develop the software AsCAM containing the procedures and database design and technology information. This software can effectively solve the problem of technology preparation of small-scale assembly plant in construction of the circuit assembly of the product and flow diagram of assembly.

The paper contains the results of the research carried out to create new approaches to ensure the high accuracy of the precision detail's manufacture, which will accurately determine the distance of the tool to the workpieces, which greatly affects the accuracy of the detail's manufacture by the automated production. Purpose of the work was to create the principles of the operation of a two-parameter measuring probe for the control system of the workpiece's setting relatively to the instrument. On based of the processing system of the informative parameters of complex electromagnetic fields (in particular, the optical range), which prevents the destruction of process equipment in the detail's manufacture for precision devices. Consequently, the principles of construction of two-parameter electromagnetic systems of control and measurement of space-time coordinates of technological objects location in the workspace of the machine are proposed. The proposed action of the probe for the information-measuring system of contact provides an increase in the accuracy of the metalworking process during the manufacture of precision details of devices, which is especially important in the processing of metals on CNC machines.
