With this instrument it is possible to record in one sweep a spectral range of 10 000 cm-1. The interferograms contain 106 points (corresponding to a resolving power of about 106) and the reproducibility of the measurements of the wavenumbers of recorded lines in emission spectroscopy is 10-7 in relative value; the accuracy of the measurements of the position of the lines, is proportional to line intensity, and is of the order of a few hundreths of mK (1 mK = 10-3 cm-1) for the strongest among them. Finally, the intensity of the weakest measurable line is one thousandth of the intensity of the strongest line of the spectrum. Compared to a conventional grating spectrometer, the Fourier transform spectroscopy has the advantage among others, of maintaining the throughput gain (Jacquinot) constant for all the lines of the spectrum; the multiplex gain (Fellgett) does not disappear entirely; it depends strongly on the intensity of the lines. The work presented here, proves clearly that the extension of Fourier transform spectroscopy to regions where the noise is principally photon-noise, is effectively possible.","PeriodicalId":286899,"journal":{"name":"Nouvelle Revue D'optique","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1976-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121968669","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}
