Motivated by the desire to image exosolar planets, recent work by us and others has shown that high-contrast imaging
can be achieved using specially shaped pupil masks. To date, our masks...
Pupil mapping is a promising and unconventional new method for high contrast
imaging being considered for terrestrial exoplanet searches. It employs two
(or more) specially designed aspheric...
We present yet another new family of masks for high-contrast imaging as required
for the to-be-built terrestrial planet finder space telescope. We call these masks
checkerboard masks. They...
The optimal configuration of a satellite formation consisting of a telescope and an occulter
around Sun-Earth L2 Halo orbits is studied. Trajectory optimization of the occulter
motion between...

An occulter is used in conjunction with a separate telescope to suppress the light of a distant star. To
demonstrate the performance of this system, we are building an occulter experiment in...
An occulter is an instrument designed to suppress starlight by diffraction from its edges; most are designed
to be circular, with a set of identical “petals” running around the outside....

We use our automated Design Reference Mission construction framework to evaluate the performance of multiple
direct exoplanet imager mission concepts on a variety of metrics including: total...
