Interferometry - Wikipedia
Interferometry typically uses electromagnetic waves and is an important investigative technique in the fields of astronomy, fiber optics, engineering metrology, optical metrology, oceanography, seismology, spectroscopy (and its applications to chemistry), quantum mechanics, nuclear and particle physics, plasma physics, biomolecular interactions,...
What is an Interferogram - Diffraction Limited
To make an interferogram, we combine light from two different sources. In practice, we use the same light source (a laser A device for producing monochromatic, coherent light. Laser is an acronym for Light Amplification by Stimulated Emission of Radiation.

Michelson interferometer - Wikipedia
The Michelson interferometer is a common configuration for optical interferometry and was invented by the 19/20th-century American physicist Albert Abraham Michelson. Using a beam splitter, a light source is split into two arms.
Interferogram - an overview | ScienceDirect Topics
An interferogram is considered an equation in three unknowns namely background, modulation, and object phase. Therefore, a set of N ⩾ 3 interferograms changed in known phase steps build a N × 3 system of equations. A calibrated phase shifter introduces experimentally the known phase steps sequentially with the time.
Fourier Transformation of an IR Interferogram. In this laboratory exercise we will use a Fourier Transform Infrared (FTIR) spectrometer to generate a time domain Interferogram for a simple organic liquid. We will then Fourier Transform this data to obtain a frequency domain Infrared Spectrum for the sample.
Interferogram: the pattern formed by the net irradiance as a function of delay. at this time, constructive interference destructive interference here Why is this interesting? One reason: because interferograms are easy to measure using a Michelson interferometer. What if …

Interferometry is an imaging technique in which waves are superimposed in a manner to cause interference. NISAR will use interferometry to compare three-dimensional observations of the same scene on Earth to reveal surface motion and change.
