Wireless frame synchronisation

View News Story - Wireless frame synchronisation

Frame sync’ing cameras together is one of the main benefits of using digital high speed cameras rather than analogue. The idea of frame locked cameras was unheard of in the days of cine cameras. Until very recently, frame sync’ing wirelessly has just been a pipe dream. Most digital high speed cameras have cables for sync’ing,…

Frame Synchronisation

View News Story - Frame Synchronisation

High speed cameras are often synchonised, (aka genlocked, framelocked) together. All but the most basic cameras include the ability to input or output a sync signal for this purpose. Creating movies with frames captured at exactly the same instant has many uses, including: Accurate motion analysis of an event with cameras at multiple viewing positions…

View Producing 3D Movies

Producing a 3D movie is not as complicated as you might think. There are a few different formats of 3D file that are played on various devices. Here, I’ll explain how to produce a side-by-side movie, which seems to be the most common for playing on a 3D TV. A side by side movie made…

View Particle Image Velocimetry – see the flow

Particle Image Velocimetry (PIV) is an optical method of flow visualisation, where particles are tracked, to form a vector diagram, showing the flow pattern and flow rates of a fluid. It is generally carried out in 2D, but 3D PIV is a powerful tool for more advanced users. PIV can be carried out in liquids…

Framing Rate vs. Shutter Speed

View Framing Rate vs. Shutter Speed

Many users of high speed cameras often ask about the difference between framing rate and shutter speed (aka exposure time). Both are to do with time, and to a certain extent there is a dependancy of one on the other, so I can fully understand where the confusion comes from. In short, frames per second…
