... 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 . ...

Limiting Resolution . The terms MTF cutoff frequency, limiting resolution, and resolving power have all been used interchangeably to define the smallest target that can be resolved with an imaging system. Although the term 'limiting resolution' is often used to describe the smallest target length that can be imaged. ... For example, high frequency targets can be reproduced from their low frequency fundamentals and phase errors can produce 'phantom' images that resemble high frequencies. ...

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. ...
