概要
- 論文の詳細を見る
A method of realizing two-dimensional temperature distribution in water by means of optical Fourier transform is described. Using this method, the water temperature distribution is obtained from a small spatial domain where an ultrasonic beam perpendicularly intersects a laser beam. The temperatures are measured at 64 points in a 28×28 mm^2 region. The error of measurement is within 1℃. The present method can be applied to measurements of concentration or density, because in this method, the water temperature is obtained from the acoustic wave velocity.
