摘要：The present invention utilizes, in combination, an irradiator, a screen and anoptical sensor. The irradiator generates a parallel light band to form a linear imageregion on the screen. A spherical flying object is made to pass transversely through theparallel light band to form a silhouette within the image region. The silhouette isdetected by the optical sensor to determine the instantaneous spatial position of theflying object. The position thus determined may be utilized for example to calculate theinitial trajectory angle of a golf ball hit from a fixed position.
