High-Precision Astrometry Using a Diffractive Pupil and Advancements in Multi-Laser Adaptive Optics
Detection of earth-size exoplanets using the astrometric signal of the host star requires sub-microarcsecond measurement precision. One major challenge in achieving this precision using a medium-size (< 2-m) space telescope is the calibration of dynamic distortions. A diffractive pupil can be use...
