The method of ultraviolet spectrum analysis is generally adopted in traditional ammonia concentration detection with a deuterium or xenon lamp, and its cost is relatively high. In this paper, white light-emitting diodes of a lower cost are used as an alternative light source. Then experimental research on ammonia concentration detection is carried out, and the results are compared with those using white light-emitting diodes, deuterium, and xenon lamps. The results show that, under the same experimental conditions, using white light-emitting diodes to measure the ammonia concentration can achieve the same accuracy as using deuterium or xenon lamps. This conclusion provides a solution for light source selection for ammonia concentration detection with low cost and guaranteed accuracy.","PeriodicalId":210050,"journal":{"name":"Оптический журнал","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121489015","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}

It is based on swapping of data bits belonging to two different channels to form two garbled bit streams. The encryptor and decryptor designs used here can be implemented by using commercially available components. The performance of the proposed technique is evaluated at the system level by considering multiple spans of optical fibers with in-line optical amplifiers. Numerical simulations show that the decoded bit streams can be recovered with acceptable bit error rates after 500 km.","PeriodicalId":210050,"journal":{"name":"Оптический журнал","volume":"126 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128420284","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}
