| Abstract: | The input pupil of interferometry-based observation instruments is necessarily segmented. Since the Optical Transfer Function (OTF) of any optical instrument observing in incoherent light is the auto-correlation of its input pupil, it follows that any combinations of size and position of each pupil segments will have an impact on the OTF behavior and therefore on the quality of the output image. The goal of this study is to propose computational geometry methods allowing to find pupil geometries leading to an isotropic OTF support with a controlled redundancy of viewed spatial frequencies in the Fourier domain. | ||
