Paperback. Etat : New. Print on Demand. This book presents an early study of a chronograph that measured the velocity of projectiles using polarized light. Prior to this, chronographs measured the time interval between screens, and thus errors were possible. This book describes how a new method was developed using polarized light as a "shutter" for the beam. By measuring the time it takes the polarized light to change, the time it takes for the projectile to pass through the beams could be measured. The author believed this method would have many applications beyond just projectile velocity, and the book explores these applications. The book offers an in-depth look at a nascent technology in the realm of chronographs and provides a valuable historical account of the development of this technology. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. N° de réf. du vendeur 9780282176051_0
