FT-IR unit wavenumbers by dividing by 10 and taking the recip-rocal. An external source of wavelength calibration is required, since there is no high-precision laser wavelength to reference in the system. FT-IR Advantages There are three major advantages in the performance of an FT-IR spectrometer over a dispersive infrared . The PICO SCALE interferometer provides diﬀerential non-contact measurements between a target mirror and a reference mirror. This allows measuring displacements relative to a certain fixed point of an experimental setup, as well as minimization of noise. The diﬀerential displacement of these two mirrors is measured with very high.
One of the first uses of optical interferometry was applied by the Michelson stellar interferometer on the Mount Wilson Observatory's reflector telescope to measure the diameters of stars. The red giant star Betelgeuse was the first to have its diameter determined in this way on Decem In the s radio interferometry was used to perform the first high . However, they have proven useful for making very high precision measurements of simple stellar parameters such as size and position and for imaging the nearest giant stars. For details of individual instruments, see the list of astronomical interferometers at visible and infrared wavelengths. Astronomical heterodyne interferometry.
One of the primary uses of interferometry in the field of stellar physics is the measurement of the intensity profile across the stellar disk, both as a function of position angle and of wavelength. High-precision fundamental stellar . The Infrared Spatial Interferometer (ISI), run by an arm of the University of California, Berkeley, is an array of three meter telescopes operating in the mid-infrared. The telescopes are fully mobile .

Results. We determined very precise stellar masses for all systems, ranging from % to % precision level.
We combined these measurements with stellar effective temperature and linear radius to fit stellar isochrones models and determined the age of the systems. We also derived the distance to the systems with a precision level as high.

Context. The precise determinations of stellar mass at ≲1% provide important constraints on stellar evolution models. Accurate parallax measurements can also serve as independent benchmarks for the next Gaia data release.
Aims: We measured the masses and distance of binary systems with a precision. Interferometry has been a time-honored technique for surface topography measurement. Interferometric measurements of surface shape are relative measurement techniques in which the.
