• Requirements:
– 4-5 nm mechanical resolution, – active vibration control– µrad resolution for spectral scans
• Approach:
– Laser Doppler interferometer onreference frame measures absoluteposition of optics, sample.
– SMALL-RANGE flexures+ piezo-feedback respond to laserinterferometer input
– Fine scan x/y of zone plate
