Paper Abstract

Several different configurations of wavefront sensing instruments, that are based on the Hartmann sensor concept have been reported in the literature during the past years. The present paper describes experimental results that were obtained by using a novel technique that was first reported last year.1 This technique is aimed at interrogating wavefront deforming characteristics of an optical system under test by injecting a pencil beam of light (typically a diffraction limited, well collimated laser beam), that is translation scanned across the entrance aperture, and analyzing in real time the transmitted or reflected pencil beam. The two most important characteristics of the pencil beam that arrives at the receiver; i.e., the angle of arrival and intensity are both monitored simultaneously. This data is processed and displayed in a choice of formats. The present paper shows experimental results based on this diagnostic technique. The measured data is shown in the form of isometric plots of the angle of arrival. These re-sults are then compared to analytically expected behavior.
