Temperature measurement by holographic interferometry in liquids for transient flame spread
To study flame spread over liquids and liquid pool fires leading to boilover, a holographic interferometry (HI) technique was developed, which is capable of detecting a sudden and sensitive temperature change occurring in a distributed area nearly instantaneously. This was need since conventional thermocouple point-by-point measurement technique has limitations due to the effects of the wire disturbances and spatial resolutions. In both studies, it was shown that HI is a very useful temperature measurement technique, and the estimated errors are so small that it causes no significant effects when the HI data were used for quantitative analysis. Recent progress is reported on the application of HI to highly transient phenomena, such as the studies of flame spread and liquid pool fires.
