A unique electronic sensing screen apparatus for automatically measuring various parameters of moving projectiles. Projectiles pass between an artificial or natural light source and light sensors, resulting in signals from the sensors, which are processed into data showing projectile profiles or photo-like images, shock waves, velocity, angle of attack, and dispersion. The apparatus provides quick turn-around times between parameter measurements, such as those of many projectiles fired in rapid succession, and readily usable results.
