A coronagraph using a liquid crystal array and a deformable mirror for active pupil apodizing and phase correction Deqing Ren, Cal State University Northridge High-contrast imaging coronagraphs proposed until now all based on passive designs. That is, the coronagraph cannot be actively controlled to be optimized for best performance. Pupil apodizing that modifies the light transmission on the pupil is one of the promising techniques for high-contrast imaging. Here, we proposed, in the first time, a high-contrast imaging coronagraph that integrated a liquid crystal array for active pupil apodizing and a deformable mirror for active phase correction. In such a way, source errors such as the initial transmission error and wave-front error can be actively controlled and compensated based on an optimized algorithm, which is optimized for maximum contrast in the discovery area. In addition, the using of a liquid crystal array makes this system more flexible that may create any apodizing pupil, including square or circle aperture with or without central obstruction, which make a universal coronagraph possible. In this talk, I will discuss the working principle and estimated performance of the coronagraph that is aimed for the high-contrast imaging with a ground-based and a space telescope, respectively.
