Provided is an analysis system of golf ball and club head data using lasers and 4-axis light sensing. The analysis system includes a horizontal sensor array, a vertical sensor array, a control unit, and a display unit. The horizontal sensor array is installed on a floor and includes a plurality of light sensors arranged in straight lines a predetermined distance apart from each other. The horizontal sensor array receives light from a light source installed thereabove so as to detect the silhouette of a golf ball or a club head according to movements of the golf ball or club head. The vertical sensor array is installed to protrude from a floor at a perpendicularly offset angle, in order to receive a laser beam from a laser installed to a rear thereof and detect the silhouette of the golf ball when the golf ball passes through the laser beam. The control unit derives position coordinates of the golf ball in space using data of the silhouette of the golf ball detected by the horizontal and vertical sensor arrays, and calculates a ball speed, a club head speed, a ball directional angle, a ball launch angle, a club head path, a sidespin, and a flight distance, using the position coordinates of the golf ball. The display unit displays the calculations on a screen according to controlling by the control unit. The analysis system detects the flight of a golf ball after it is struck in a practice range, calculates ball speed, flight distance, direction, initial angle, trajectory, landing point, etc. and shows this data in terms of an image and numbers on a screen, and provides a detailed, three-dimensional graph showing the trajectory of the ball against a background image of a golf course, so that the user who hit the ball can easily see the analysis results.
