interferogram

[‚in·tə′fir·ə‚gram]
(graphic arts)
A photograph of a shock wave or other fluid flow, produced with the aid of an interferometer, in which the displacement of interference fringes is proportional to the density change across the fluid.
(spectroscopy)
A graph of the variation of the output signal from an interferometer as the condition for interference within the interferometer is varied.

The results of the research obtained in the format of holographic interferograms proved statements of the set hypothesis that the surface deformation character of the forged and the original reference data pages should differ.
Interferogram is generated by multiplying of the SAR image pair co-registered, which contains the topographic information but modulo 2[pi] (wrapped phase).
This method gave us a double-exposure holographic interferogram which presents the state of object at the moment of the second exposure.
Sixteen scans of the interferogram were coadded, representing a data acquisition time of about one hour for each spectrum.
To allow comparing between interferograms created from data of different wavelengths, the ALOS interferogram phase values were recomputed (and wrapped to dimensions of -[pi];[pi])to the scale of ERS/Envisat using a simple formula:
Samples of pictures of holographic interferograms of temperature fields around the cylinder and their quantitative analysis are in the Fig.
Moreover for this case a different master scene has been used and different number of interferograms.
