In brief
High-speed imaging began with Eadweard Muybridge's 1878 sequential photographs of a galloping horse. It became a research tool in the 1930s, when Harold Edgerton at MIT used stroboscopic flash to freeze motion. Since the move from film to digital sensors, high-speed cameras record from thousands to millions of frames per second for research, defence, automotive safety and manufacturing.
From novelty to essential research tool
High-speed cameras have evolved from curious inventions into indispensable tools for research, engineering and even sports science. They capture events too fast for the eye to follow, and that has changed how scientists and engineers study motion, failure and flow.
Early beginnings: capturing motion
High-speed photography dates back to the 19th century. In 1878, photographer Eadweard Muybridge set up a row of cameras along a track in Palo Alto to settle whether all four of a galloping horse's hooves leave the ground at once. Each camera captured one frame as the horse passed, producing one of the earliest sequential photographs and a forerunner of the motion picture. Muybridge later built the zoopraxiscope to project his sequences as moving images.
Étienne-Jules Marey took the idea further with his chronophotographic gun in 1882, which recorded multiple frames in quick succession, an essential step towards the cameras used today.
These early inventions were limited in frame rate and image quality. It was not until the 20th century that high-speed cameras became practical for scientific research.
High-speed imaging becomes a research tool
The 1930s marked the start of high-speed cameras as true research instruments. In the early 1930s, Harold Edgerton at MIT adapted the stroboscope to photography, using short, intense flashes to freeze motion. His images of a bullet piercing an apple and a drop of milk splashing became famous, and his methods spread quickly through academic and industrial research. As frame rates increased, high-speed cameras moved into military testing to record projectiles and explosions in ballistics work.
Their importance grew during and after the Second World War. In the Cold War era, governments and defence agencies relied on high-speed cameras in aerospace engineering and weapons testing, slowing down events such as missile launches so they could be analysed frame by frame.
Digital sensors and wider use
The move to digital sensors in the late 20th and early 21st centuries was a major leap. Film-based high-speed cameras meant slow processing, limited storage and quality loss with repeated playback. Digital sensors brought instant playback, easy storage and direct analysis.
Today's high-speed cameras record from thousands to millions of frames per second, depending on the application. Ultra-high-speed cameras reach the top of that range. Crash testing relies on them to analyse the forces in a collision, biologists use them to study how insects and animals move, and coaches use them to refine athletes' technique. See automotive and combustion, biomechanics and sports and motion analysis.
High-speed cameras are also valuable for manufacturing quality control, where they help diagnose mechanical failures, find inefficiencies on production lines and document problems for troubleshooting.
The future of high-speed imaging
Higher resolutions, 3D measurement and ever-increasing frame rates continue to push what can be observed and measured. In fields such as nanotechnology and particle physics, where events happen at nearly imperceptible speeds, high-speed cameras are expected to play a central role.
What began as an attempt to photograph a galloping horse has become a technology that supports progress across science and industry, and a reminder of how curiosity drives the tools we build to see the world in more detail.
Frequently asked questions
Who invented high-speed photography?
Eadweard Muybridge's 1878 sequential photographs of a galloping horse are among the earliest examples. Harold Edgerton at MIT turned high-speed photography into a scientific tool in the early 1930s by using stroboscopic flash to freeze motion.
