Abstract
Analysis of the first interferometric fringes recorded
at Dome C, Antarctica are presented. Measurements were taken 31 January and 1 February
2005 during daytime. Our purpose in performing
the analysis was to measure temporal fluctuations of the atmospheric
piston, which are critical for interferometers, and determine their sensitivity.
These scales are derived through the motion of the image that is formed in
the focal plane of a Fizeau interferometer.
We could establish a lower limit to the coherence time by studying the decay
rate of correlation between successive fringes. Coherence times are measured to
be larger than
