Abstract

A new auto-correlator has been developed, built and implemented. It contains eight mirrors on an optical bench, which are independent, adjustable in the nrad and nm range. A parallelogram-based delay stage moves two of the mirrors over ±15 mm with 30 nm resolution and without random parasitic motions. The paper presents the new ideas applied in the design of this device.
