Abstract
An improved interferometric system with reduced air turbulence error. The system includes an optical retarder that functions as a quarter wave plate for two harmonically related frequencies. The retarder may be formed by a pair of quartz disks cut so that the C axis lie in the plane of the disk and are oriented orthogonally relative to each other.
