抄録

The change of luminance of visualized image is caused by the motion of tracer particles or dyne transported by fluid, and it is expressed by a governing equation using the Lagrange's derivatives. The so-called spatio-temporal derivative method is well known as an image measurement technique which has a high spatial resolution. The technique also has disadvantages such as small dynamic range and the unsteadiness for the image noise. In the present paper, the principles of the measurement techniques based on the spatio-temporal derivatives are explained, and the applications are shown. The spatio-temporal derivative method would have much wide application field.
