Abstract
Experimental results are presented for an adaptive optics system based on a quadrature Twyman–Green interferometric wave-front sensor. The system uses a circularly polarized reference beam to form two interferograms with a π/2 phase shift. The experiments conducted used Kolmogorov phase screens to simulate atmospheric phase distortions. Strehl ratio improvements by a factor of 8, to an absolute value of 0.45, are demonstrated.
