A structural diagram of such a spectrometer is presented and the choice of its element base are discussed. The modes of operation of the spectrometer based on AOTF for various types of control signal are considered: a signal with linear frequency modulation (LFM) and a signal with stepwise frequency tuning (SFT). The results of computer simulation of the spectrum spread function for different types of modulation are presented. The results show broad prospects for the use of an AOTF-based spectrometer when using the SFT in monitoring systems for scanning a specific set of spectral lines, from which it is possible to obtain comprehensive information about the state of the controlled process. An essential advantage of the spectrometer when using the SFT-modulation is its speed, because in this case there is no need to scan the whole range and therefore the time of spectrum analysis is significantly reduced.","PeriodicalId":303530,"journal":{"name":"2020 Wave Electronics and its Application in Information and Telecommunication Systems (WECONF)","volume":"173 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122998705","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the analysis of time diagrams, integral equations are written, the solution of which allows us to derive calculation formulas. The results of calculations are presented.

The requirements for the image stabilization algorithm in the video streaming processing system for unmanned aerial vehicles (UAVs) are formulated. An improved modification of the video stabilization algorithm is proposed based on a comparison of key image points. As a descriptor of the found local features, the modern high-performance FREAK method was applied, surpassing existing algorithms both in the speed of generation and comparison of feature vectors and in the accuracy of comparison and resistance to image transformations. This made it possible to significantly increase the performance of the stabilization algorithm and improve the quality of stabilized video images due to a more accurate calculation of the parameters of inter-frame transformations, which, in turn, depends on the accuracy of matching sets of singular points. The results of testing the proposed algorithm on real and synthesized video sequences are presented.","PeriodicalId":303530,"journal":{"name":"2020 Wave Electronics and its Application in Information and Telecommunication Systems (WECONF)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125234043","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
