How do interferometers work? - Explain that Stuff
WebAn interferometer can be defined as an instrument that uses two or more beams of light to make precise measurements by analyzing the interference between them. Interferometry plays a vital role in the advancement of modern science. The Laser Interferometer Gravitational-Wave Observatory (LIGO) is a perfect example of this. WebSingle Baseline Interferometry4 The oscillations in the sensitivity pattern have the same direction as the baseline, with a period determined by the baseline length in wavelengthsbaseline, with a period determined by the baseline length in wavelengths Point Spread Function for the VLA5 The uv-coverage is the set of all baseline vectors. Web19 jul. 2024 · Medicus began with a brief introduction to how interferometry works: “there is a reference wave, and light reflects off the optic. The comparison of these two ways tells you the shape of the optic.” “Sensors in the interferometer read the wavelength of the light and convert that to a height. curnutt hafer llp
