A new approach to linear measurements in the nanometric range based on the measurement of the transit time of an electromagnetic wave between two points that bound a linear region is proposed. Frequency methods that make it possible to increase the r

The use of an optical circulator to calibrate (check) linear measures by a frequency method is proposed. The possibility of remote frequency comparison of linear measures, kept in widely separated laboratories, is considered.

An optical device is described that maintains undamped circulation of a single short light pulse in a closed loop. A circulator based on the latest fiber-optic components can be used as a frequency measure in the radio range and also for frequency me

A unique design is suggested for a phase inverter with the output signal phase difference regulated by the frequency of an external frequency synthesizer. We examine the possibilities of using it as a basis for a phase-angle calibrator (standard) as

Experiments on rotating superfluid $^{3}\mathrm{He}$-$A$ in an open cylindrical geometry show a change in the NMR line shape as a result of rotation: The amplitude of the peak decreases in proportion to $f(T)g(\ensuremath{\Omega})$, where $\ensuremat
