Abstract

The motion of a golf ball or other projectile is determined as it passes through substantially-parallel fields of view (3, 4,-45, 46; 55, 56) of two line-scan sensors (1,2; 43,44; 53,54) that are spaced apart from one another. The fields of view of the two sensors are each substantially-planar or wedge- shape with respective mid-way planes offset or otherwise from one another, and each sensor responds at successive intervals of time to the angular position of the projectile in its field of view. From the sample measurements of angle, velocity vectors of the projectile and its direction are calculated.
