We present an experimental study of the flutter instability of a flag. Our experiments are performed in a low turbulence horizontal wind tunnel. The flags tested are made of paper or plastic of different flexural rigidities. One end of the flag is clamped to a profiled and vertical mast, the other end is left free. At low velocities, the flag is parallel to the flow and motionless. Above a critical wind velocity, the flag exhibits periodic flutter. The bifurcation is subcritical and the system shows a strong hysteresis cycle. We particulary focus on the variation of the instability threshold with respect to two non-dimensional parameters: the mass ratio and the aspect ratio. When the mass ratio increases, different flutter modes appear. We have studied systematically the effect of aspect ratio on the instability threshold. In agreement with a recent theoretical study [1], the critical velocity is a decreasing function of aspect ratio as long as three-dimensional effects are negligible (when the flag span is not too large).

Illumination Mode

The tilted beam illumination method is used to improve the resolution comparing with the axial illumination mode. Using this advantage, a restoration method of several tilted beam images covering the full azimuthal range was proposed by Saxton, and experimentally examined. To make this technique more reliable it seems that some practical problems still remain. In this report the restoration was attempted and the problems were considered. In our study, four problems were pointed out for the experiment of the restoration. (1) Accurate beam tilt adjustment to fit the incident beam to the coma-free axis for the symmetrical beam tilting over the full azimuthal range. (2) Accurate measurements of the optical parameters which are necessary to design the restoration filter. Even if the spherical aberration coefficient Cs is known with accuracy and the axial astigmatism is sufficiently compensated, at least the defocus value must be measured. (3) Accurate alignment of the tilt-azimuth series images.
