Scientific paper
Two sensor systems for the direct detection of nonsolar planets from earth orbit are evaluated: (1) an apodized visual telescope (APOTS), and (2) a spinning infrared interferometer (IRIS). Their performance characteristics and technology requirements for a five-year mission are determined. The simpler instrument, APOTS, requires a substantial improvement in mirror fabrication techniques before it can approach its full performance potential. The IRIS requires technology development in the areas of long-lifetime cryogenic systems and of active control techniques. Technology issues of secondary importance are discussed.
