Motion-Capturing Method


Figure. Concept of motion capturing method.

Advantages in unsteady pressure/temperature measurements in:

1.  Moving / free flight object
2. Oscillating / vibrating object
3. Deforming object
4. Time variation in illumination

Application Examples

Surface pressure over a free flight object.
Unsteady surface pressure over a rotating blade.
Unsteady surface pressure over a fluttering airfoil.
Shock detection under transient plasma as a time dependent illumination.

Key Person

Currently this topics is done by Daiki and Tatsu.
