- •
The new beam shutter configuration for optical laser sensors is tested on two disks.
- •
The Blade Tip-Timing technique is verified by the strain gauge measurements.
- •
A new method to identify the operative deflection shape of the disk is proposed.
- •
The travelling operative deformed shape is identified when small mistuning occurs.
