摘要:

调零干涉测量法已被确定为探测太阳系外行星的一种有竞争力的技术。该技术包括将相位不同的望远镜对结合起来,有效地消除明亮恒星的光线,并揭示伴星的暗淡光芒。我们已经制造并测试了单色光的集成光学组件,它结合了一个线性阵列的4个望远镜在零模式设想的天使和狼(1997年)。我们的测试台模拟天空中恒星的运动。测试表明,调零缩放为基线延迟的四次方。

英文摘要:

Nulling interferometry has been identified as a competitive technique for the detection of extrasolar planets. The technique consists in combining out-of-phase pairs of telescopes to null effectively the light of a bright star an reveal the dim glow of the companion. We have manufactured and tested with monochromatic light an integrated optics component which combines a linear array of 4 telescopes in the nulling mode envisaged by Angel & Wolf (1997). Our testbench simulates the motion of a star in the sky. The tests have demonstrated a nulling scaling as the fourth power of the baseline delay.
