Example sentences for: interferometer

How can you use “interferometer” in a sentence? Here are some example sentences to help you improve your vocabulary:

The relatively large number of complete cycles in the data, however, yield very reliable information about the periodicity; and if there is more than one rhythm, the two periods can more likely be resolved by Fourier-based spectral analysis in the same manner that two wavelengths of light can be resolved into separate lines in a spectroscope [ 60 ] . The relationship between the number of cycles present in the data record and resolution is mathematically equivalent to the gain in spectral resolution with the increase in distance between mirrors in an interferometer [ 60 ] . On the other side of the coin, if a very short series is transformed, information about local conditions in the time domain becomes more precise at the expense of resolution in the frequency domain [the information in the time domain is more precise; but the resolution in the frequency domain is greatly reduced [ 38 ] .
These issues are the same as those connected with resolution involved in optical interferometry and obey the same laws [ 60 ] . For example, the wider the spacing of the mirrors in the interferometer, the better the resolution [ 60 ] . Resolution in digital signal analysis is the capacity of a given system to separate two arbitrarily close frequencies into distinct peaks in the spectrum.
