Abstract
  • High resolution images of a dim companion in a binary star system can be obtained using a Digital Micromirror Array (DMA) as an optical mask. Imaging can be problematic because the intense light from the main star can saturate the detector and leave the companion unnoticed. Placement of the DMA in the image plane allows for the replication of widely-used optical masking techniques. A laboratory model of a binary star system with a bright source that is about 5000 times brighter than the dim companion is resolved at 25 ± 5 arcseconds. Another simulation uses the pixels of a monitor to acquire an angular resolution of 3.4 ± 0.1 arc seconds. The system uses a 12” Cassegrain reflecting telescope to focus light onto the 1024 x 768 pixel D4100 DMA, the light is then taken from the masked image plane to a charge coupled device (CCD) via a 150 mm lens. Lyot Stop masks and Aperture Masking Interferometry will also be discussed.
