| Research Abstract |
The author has developed a laser-applied measurement technique based on laser-induced thermal acoustics (LITA) for short-time and unsteady temperature history with micro-second-order time resolution. The author developed an experimental apparatus to reveal temperature history caused by planer shock with shock tube. The measurement technique has successfully revealed temperature history caused by shock waves, with accuracy of 10% (at maximum). The developed measurement technique would be utilized to reveal, the temperature profile of flow field around aerospace craft at supersonic speeds, which the thermometer with micro-second-order response time is required to measure.
