Illustration of the ultrafast LS-CUP laser camera that captures what happens during combustion.
By illuminating a sample surface with short laser beam pulses, it is possible to film sequences of various chemical and physical reactions. A research team that included researchers from the University of Gothenburg has now developed the world’s fastest single-shot laser camera, which is at least a thousand times faster than today’s most modern equipment for combustion diagnostics. The discovery has enormous significance for studying the lightning-fast combustion of hydrocarbons.
What happens to a material that is burned in different conditions? To investigate this question, researchers use a laser camera that photographs the material in a two-dimensional layer, known as LS CUP (single-shot laser sheet compressed ultrafast photography). By observing the sample from the side, it is possible to see what reactions and emissions occur over time and space. Researchers have used LS-CUP to study the combustion of various hydrocarbons.
