Abstract
The Princeton occulter testbed uses long-distance propagation with a diverging beam and an optimized occulter mask to simulate the performance of external occulters for finding extrasolar planets. We present new results from the testbed in both monochromatic and broadband light. In addition, we examine sensing and control of occulter position using out-of-band spectral leak around the occulter and occulter position tolerancing. These results are validated by numerical simulations of propagation through the system.
