Memory and recording workflow

Internal RAM, removable CineMag and continuous streaming are three ways of handling the data volume of high-speed imaging; the choice changes the recording time and the pace of the test.

Trigger and synchronization

The camera records in a loop and the trigger sets time zero; the pre-trigger keeps what came before and synchronization aligns cameras, lasers and instrumentation on the same clock.

Lenses and optics for high-speed imaging

A wide aperture, the right focal length for the field of view and, when the subject is small or far away, macro lenses, microscopes or long-distance lenses.

Lighting for high-speed imaging

With exposures of microseconds, light is the scarcest resource: use continuous flicker-free sources, high-intensity LED or pulsed laser, and calculate the exposure before recording.

fps versus resolution: how to choose the camera

Choosing a high-speed camera means deciding between temporal and spatial resolution: 1 Mpx at 76,000 fps and 4.2 Mpx at 9,350 fps solve different problems.

What is a high-speed camera

A high-speed camera records thousands to hundreds of thousands of frames per second to play back in slow motion events that are too fast for the eye, with sensors, memory and triggering designed for the purpose.

Frame rate and recording time

Choose the model and the resolution to see the maximum fps and estimate how long the memory records.

Maximum exposure without motion blur

Find the longest exposure at which a moving object still looks sharp in the image.

Lens focal length

Find the focal length that frames the desired field of view at a working distance.
