Abstract: A golf ball trajectory measuring system is provided, which measures the trajectory of the golf ball without decline of the precision through a number of light receiving elements. A golf ball trajectory measuring system comprises: a plurality of light emitting units(40) which are placed at the spot distanced at an interval from the golf ball hitting point and include light emitting elements emitting the infrared ray; a plurality of light receiving units(10) which are placed at the spot adjacent to the emitting element(42) and include light receiving elements sensing the infrared ray reflected by a golf ball; and a light shield wall(14) preserving interference between the infrared ray sensed from the light receiving element and the infrared ray emitted from the emitting element.
