Displacement measurement by Single-grating heterodyne Interferometry

Not Accessible

Your library or personal account may give you access


We presented a displacement measurement system based on single-grating heterodyne interferometry. Our prototype system was demonstrated to achieve a relative measurement accuracy of better than 69 nm with standard deviations of less than 28 nm.
