Laser beam interferometric modulation technique for moving object trajectory correction

摘要

The laser beam interferometric modulation technique has an object guided by correction signals from a laser beam. The laser beam tracks the object position, and error signals are produced. The error signals are relayed to the object receiver (6), using modulated codes. The codes are passed to an interferometer (3) which produces an interferometric pattern at the moving object receiver after passing through a lens (5).
