A trajectory calculator receiving data indicating initial values of golf ball flight angle, velocity and spin, calculates the apparent elevation and deflection angles at which the golf ball would be seen by an observer at the launch point. An optical object projector projects an image representing the golf ball on a screen. The size of the image decreases with time to yield the apparent perspective size decrease with range. An optional exerciser console enables input of changeable environmental quantities.

Golf ball trajectory presentation system

A video data acquisition system takes at least two snapshot views of selected points on a golf ball in the immediate post-launch time period. Analog video data are converted to digital data for analysis in an external system. A trigger generator, of a type well known in the art, senses the existence of a certain set of conditions associated with the launch of the golf ball and thereupon generates a set of precisely timed impulses which trigger the following sequence of events:

Monitoring system for measuring kinematic data of golf balls

An improved light emitter assembly for use in biomechanical electro-optical systems is disclosed. The device comprises a curved rigid or semi-rigid body to which at least three spaced light emitting diodes are affixed. The body is preferably cylindrical or hemispherical.

Light emitter assembly

A photographic projection screen formed of separate parallel filaments having a center-to-center spacing equal to their diameters allows a projectile to be driven through it with minimal disturbance to image projected upon it.
