A system and method for X-Y alignment and tracking of moving targets having angular displacement with a fiber optic sensing surface comprising a sensor (5, 6, 17) comprising a sensing array (5) for providing an indication of the position of a beam of radiation incident on the sensing array, a radiation source for providing a beam of radiation (laser), means for simultaneously directing said beam of radiation along two separate paths (4), inhibiting circuitry for alternately inhibiting travel of the beam of radiation in each of the separate paths (13, 14), reflecting means (3, 15) in each path deflecting the beam of radiation in each path to the sensing array and responsive to the position of a beam of radiation incident on the sensing array for altering the position of the beam relative to the sensing array and circuitry responsive to the position of the beam for providing a desired object parameter indication (18, 19).
