Abstract

PURPOSE: To measure the ball spin amount instantly with non-contact, by commonly providing the light projection and photo detection planes under the space through which a ball passes.
CONSTITUTION: The light projection plane 4 and the photo detection plane 5 of optical fiber are provided beneath the space through which the ball 10 passes, the reflection marks 1, 2 are stuck on the circle having back spin for the ball with a given angle θ, and light is projected on the marks 1, 2 via the plane 4 from the lamp 6 with the passage of the ball 10, and the reflected light is detected with the photo detector 7 via the plane 5. Further, the time interval t is obtained from the both detection signals with the marks 1 and 2 and the spin amount S is calculated from the equation of S=(60×θ)/(t×360) rpm.
