An interferogram is generated by making measurements of the signal at many discrete positions of the moving mirror. A Fourier transform converts the interferogram into an actual spectrum.

An interferogram is defined as the pattern produced by an interferometer that reflects the degree of mutual coherence between two combined beams, capturing information essential for extracting the …

The two beams are combined together to make an interferogram. Interference of light is very simple to understand if you think about waves on a pond. If you throw in two stones into a pond, the expanding …

Jul 23, 2025 · The image produced is known as an interferogram. It looks a bit like a rainbow-colored oil slick on the surface of water. This “fringe” of colored pixels shows the difference in signal phase …

Dec 11, 2024 · Volcanologists use interferograms to detect unrest by observing how the surface of a volcano is deforming in response to migrating magma beneath the ground. We can see changing …

INTERFEROGRAM definition: a photographic record of light interference patterns produced with an interferometer, used for recording shock waves and fluid flow patterns.

Dec 6, 2016 · The meaning of INTERFEROGRAM is a photographic record made by an apparatus for recording optical interference phenomena.

In this informative video, we will break down the concept of an interferogram and its role in Fourier Transform Spectroscopy. The interferogram is a crucial element in analyzing light and...

Just like sets of ripples meeting in water, the combination of radar signals that have different phases sets up interference patterns - hence the term 'interferogram'.

Aug 2, 2016 · Moiré patterns are extremely useful to help understand basic interferometry and interferometric test results. Figure 16.1 shows the moiré pattern (or beat pat-tern) produced by two …
