1. A launch monitor system for measuring launch conditions of an object moving in a predetermined field-of-view, the system comprising:
- a light source directing light into the predetermined field-of-view at least when the object is in the predetermined field-of-view;
a first camera unit pointed toward the predetermined field-of-view, wherein the first camera unit captures at least a first pair of images of the object on a single frame while the object is moving in the predetermined field-of-view, and wherein the first pair of images correspond to electronic activations of a first electronic shutter;
a second camera unit pointed toward the predetermined field-of-view, wherein the second camera unit captures at least a second pair of images of the object on a single frame while the object is moving i the predetermined field-of-view, and wherein the second pair of images correspond to electronic activations of a second electronic shutter;
a computer to control the system and determine the launch conditions of the object from said images;
a calibration fixtore having reflective markings in at least three different planes;
a line-of-sight of each camera unit; and
at least one telescoping member for calibrating the system, wherein said calibration fixture includes a receiving element for receiving an end portion of said telescoping member, thereby placing the calibration fixture at an intersection of line-of-sight of the camera units.

Abstract
A launch monitor system including a light source and at least one camera unit with an electronic shutter. The camera unit captures at least one image of an object in flight when the electronic shutter is activated. A computer receives signals related to the image and computes launch conditions for the object. The system also computes and displays object trajectories from the computed launch conditions and a predetermined set of lift and drag parameters which account for the characteristics of the object and the atmospheric conditions.
