Two-Mirror Apodization for High-Contrast Imaging

  title={Two-Mirror Apodization for High-Contrast Imaging},
  author={Wesley A. Traub and Robert J. Vanderbei},
Direct detection of extrasolar planets will require imaging systems capable of unprecedented contrast. Apodized pupils provide an attractive way to achieve such contrast but they are difficult, perhaps impossible, to manufacture to the required tolerance and they absorb about 90% of the light in order to create the apodization, which of course lengthens the exposure times needed for planet detection. A recently proposed alternative is to use two mirrors to accomplish the apodization. With such… CONTINUE READING
