Basics of High-Speed Video Camera
What is High-Speed Video Recording?
High-speed video recording is the science of capturing images of very fast phenomena that cannot be observed by the human eye.
Using a high-speed video camera enables the observation of ultrafast phenomena, such as those occurring in less than 1 microsecond.
What is a High-Speed Video Camera?
While a typical home video camera captures video at about 30 frames per second (fps), a high-speed video camera can record video at hundreds of fps or more. High-speed video cameras are used for varied applications, such as slow-motion sports footage, observation of collision phenomena and shockwaves, and destructive observation in material testing. Shimadzu’s high-speed video camera delivers outstanding performance in capturing ultrafast phenomena at more than 1 million fps (Mfps).

Visualizing High-Speed Phenomena
In this video, we can observe a single droplet as it falls into water at a frame rate of 1,000 fps (kfps).
High-speed video cameras allow us to capture high-speed phenomena that would be impossible to visualize using a conventional video camera.

Magnifying an Object
In this video, we can observe popcorn kernels popping at a frame rate of 10 kfps.
The unmagnified popcorn is still visible in the field of view (FOV) after 10 msec. However, in an imaging system at 3× magnification, the popcorn moves out of the FOV. The higher the magnification, the sooner the object must be captured before it moves out of the FOV. For this reason, high-magnification imaging systems using microscopes and the like require high recording speeds.
