Abstract
An apparatus for use in determining spin characteristics of an appropriately configured rotating object, such as a golf ball, includes a transmitter, a receiver, and a demodulator. The object is configured for reflecting radiation of at least a first frequency in a modulated fashion corresponding to at least one spin characteristic of the object. In this regard, an appropriately configured object may include at least one contrast area comprised of a material having different reflectivity than the rest of the object to electromagnetic radiation of at least the first frequency. The transmitter is positioned for transmitting electromagnetic radiation of at least the first frequency at the object. The receiver is positioned for receiving at least a portion of the modulated reflected radiation. The transmitter and receiver may comprise a single transceiver unit. The demodulator detects the modulated nature of the reflected radiation received by the receiver and outputs a demodulated signal including information about at least one spin characteristic of the object.
