Gas type Lineup
In the combustion measurement by LIF, it is possible to measure the molecular species of gas such as acetone, OH, CH, NO and their instantaneous distribution.
The system configuration varies depending on each gas type.
Acetone （Nd：YAG laser + CCD camera）
The easiest method is acetone LIF which seeds acetone at very high evaporation pressure in the flow field at room temperature.
This acetone absorbs in the range of 225 nm to 320 nm with the maximum value of 280 nm.It fluoresces for a short time in a wide range from 350 nm to 550 nm.
A CCD camera without an image intensifier can obtain a signal with sufficiently high resolution.
