High contrast imaging, also known as extreme adaptive optics, has been a topic of research in the astronomic community as an approach to image dim objects near bright objects, such as extra-solar planets. There are a variety of techniques ranging from coronagraphs, shaped pupils, pupil apodization, and the use of multiple deformable mirrors that have been employed to improve the contrast between the two objects. We integrated shaped pupils into our adaptive optics system. Here we will present experimental results exploring the viability of using our testbed to perform dim object detection using shaped pupils in the presence of turbulence.
