In the Olympics 100-meter sprint, just 0.08 seconds determined the difference between silver and gold — that, and a 10,000-frames-per-second camera behind the photo finish.

The official camera recording that photo finish and ones just like it throughout the games actually isn t from a big camera company though they use different Nikon lenses depending on the event , but Swiss watchmaker Omega.

It has recorded the finishes for the past 84 years.

In the latest tech being used at Rio, the finish line camera, called the Scan O Vision Myria, doesn t take your typical 3:2 aspect ratio photograph.

Instead, the camera scans just a small portion of the finish line at 10,000 frames per second, putting vertical slices together to create a detailed image.

An inclinometer adjusts the finish line camera to the optimal height, since different events have different rules on what needs to cross the finish line first.
