Abstract
A method for determining the acceleration due to gravity is suggested. Two falling interferometer reflectors illuminated by a laser are used. The falling reflectors are separated by a AT and thus have a constant velocity differential, this generates a frequency linearly proportional to acceleration ( g = kf ) Thus, the metrology of measuring g is simplified by having g linearly proportional to frequency.
