History of the Ballistic Chronograph
The history of the ballistic chronograph dates back to the 18th century, with the first attempts to measure the speed of bullets. In 1742, Benjamin Robins, a British mathematician, developed the ballistic pendulum, which measured the speed of a bullet by recording the movement of a pendulum struck by the bullet. This was an important step, although it was not a chronograph in the modern sense.
In 1865, artillery captain Le Boulengé developed a chronograph that used the rotation of a drum to record the time a bullet passed through two points. Later, in the 19th century, Francis Bashforth introduced an electromechanical chronograph that used wires cut by the bullet to activate a time-recording mechanism. During the 20th century, ballistic chronographs evolved further with the introduction of optical sensors, radar and digital technologies.
