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.

If and only if no such band exists, then the interferogram is smooth with respect to the chosen sampling nodes, and missing to sample exactly at [x.sub.0] has no profound impact.
As it will be shown in Section 3, the grating's period needs to be 600 nm; hence a phase maskproducing a 600 nm period interferogram has been designed.
The object's heights are obtained in the same fashion as in noncoherent interferometry, by adding the interference patterns obtained by the different discreet wavelengths to obtain the interferogram and calculating the position of the centered maximum of the interferogram.
