For the section of film measured, the Veeco software calculated the vertical distance between both interferograms
and consequently an average co-PET thickness value.
6 it is showns optical scheme for recording holographic interferograms
of the vibrating spring: 1--vibrating spring; 2--high-frequency signal generator; 3--amplifier.
The satellite reached its operational orbit on 7 August and just 12 days later, its radar images were used to generate interferograms
that map the topography of parts of Italy and Norway.
Polarization sensitive evaluation of the interferograms
can give additional information about sample birefringence enhancing image quality.
Field engineers empirically chose some combination of commercial optical filters by checking the corresponding interferograms
The acquisition of interferograms
is performed digitally with a color CMOS camera.
The radar targets, only slightly affected by decorrelation, allow creating a set of (N) differential interferograms
all referred to a unique master, regardless of temporal (even year long time spans) and normal baseline values.
are not useful as measures of instrument performance.
The resultant interferograms
are recorded as image stacks and converted into height data.
Instructions and diagrams are provided for interpreting interferograms
, and for testing curved surfaces, spheres, conics, concave mirrors, and other components of an optical system.
5] overcame this limitation by measuring the phase shift between interferograms
recorded with the sample placed alternately in subbeams I and II (Fig.
Spectra computed from 128 coadded interferograms
(collection time -50 s) were collected continuously before and during the treatment.
