Abstract
In absolute gravity measurements, a laser interferometer tracks the motion of a free falling retroreflector. The value of the local acceleration due to gravity is obtained by timing the traveling interference fringes. This paper presents the accuracy assessment of digital fringe processing for the extraction of gravity value from the digitized data.
