Abstract

A method of wave-front tilt sensing (sensing wave-front fluctuations) that uses two quadrant detectors (QD) is described in this paper. The error in the detection of wave-front tilt that is caused by dispersion of the intensity distribution at the aperture of the receiving telescope can be reduced. The tilt can be detected more accurately than when the conventional single focal plane QD method is used. when the intensity distribution is not uniform. A function to extracting the variation in a wave-front tilt was confirmed by observation of a fixed star.
