MÖBIUS BAND INTERFEROMETER AND ITS APPLICATION TO FOURIER SPECTROSCOPY

The first experiment will comprise a Fabry-Perot interferometer crossed with an echelle spectrograph to give a spectral resolution in the fringes of about 0.03 .A at 2 800 A

(ii) When the variations in thickness occur within the coherence area of the illuminating radiation, the amplitude reflection coefficients must be averaged and the

- Une lame cristalline uniaxe (( Z cut )) placee entre deux polariseurs circulaires identiques donne un reseau de franges qui est la transformke de Fourier du spectre

Channel 4 of the output system records the moire fringes whilst Channel 5 records temperatures and the relative azimuth of the biaxial Sun-seeker (descri- bed

The instrument is currently being used to measure at high resolution the vibrational spectrum of gaseous hydrogen induced by a strong electric field.. To attack such problems

Equation (1) gives a form that, when N is greater than its minimum legitimate value, contains the inten- sity error due to a finite resolution (path difference)

Il existe des preuves que le traitement de la malformation lymphatique peut être effectué efficacement avec une chirurgie ou une sclérothérapie, mais des études

One can avoid the contribution of the background to the signal, when the spectrum under study is constituted of narrow lines by using wavelength modulation spectroscopy ; but
