1. Optical static Fourier spectrometer
Static Fourier spectrometers are often used for spectral measurements of the ionosphere emissions. There are two main advantages of Fourier spectrometers (FS) - large geometric factor and high spectral resolution; these parameters are two orders better than for grating spectral instruments. ... In scanning Fourier spectrometer optical and electric modulation of signal is used to avoid this problem, for static Fourier spectrometer there are no such ways. ...

7. Wavelength Calibration at Moderately High Resolution
... The calibration of astrophysical spectra in wavelength based on calibration lamp data suffers from different kinds of uncertainties. Besides inaccuracies in the observational phase, common data reduction practice adds ``pixelation'' errors, due to the fact that the centering method does not use the correct PSF. These model mismatch errors depend, for a given feature, on the sub-pixel location of the line center (David & Verschueren, private communication). ...

11. Transparency of the Stochastic Background
Next: Galactic Gravitational Wave Background Previous: Structure of the Galaxy . We will call ``transparency'' of the background the ability of the observer to detect a gravitational wave signal other than that produced by binary systems, by means of adjusting variable parameters of an imaginary GW detector (namely, its angular resolution and frequency band), so that less than one occasional binary system falls into the detector's beam at a given frequency in a given direction. ...

... December 21, 1997 . ... Advantages are briefly discussed of gaining in spectral resolution, which is accompanied by losses in signal level, as compared with the attempts to improve the accuracy of measurement of line parameters by means of rising the S/N ratio alone with increasing the exposure time. To partially solve the problem of observations of faint objects at the BTA a new design echelle spectrometer is proposed. high resolution spectroscopy . ...
