Mid-Infrared Adaptive Nulling for the Detection of Earthlike Exoplanets
2010
Publications of the Astronomical Society of the Pacific
Evidence of the habitability of nearby exoplanets could be found with future space missions using the technique of nulling interferometry. A nulling interferometer selectively suppresses the glare of starlight while allowing the light from planets to be detected. Here we report the first demonstrations of broadband mid-infrared nulling at the level required to enable such a space mission. In three separate 6 hr measurements, mid-infrared nulls were demonstrated at a mean level less than 1:0 ×
