A piezoelectric motion detector is disclosed. The device is particularly suitable for use in analyzing a golf ball when hit from a golf tee (60). A piezoelectric film (68) is affixed to the bottom of a tee having a base (62). A signal generated by the piezoelectric film (68) is amplified and is used, for example, to open a camera shutter and initiate a sequence of light flashes. <IMAGE> |
