Abstract

The apodization technique has been applied to refracting telescopes but rarely to reflecting telescopes. This paper reports results obtained using a 16-sec of arc f/11 Cassegrain telescope. Aperture shapes were determined by imposing the condition that the diffraction pattern along one direction in the image plane be defined by a Sonine diffraction pattern. Polaris (α-UMin) and its companion were used as the test system.
