Abstract MARTIN, C. AST-9618811 The goals of this project are (1) to make possible new ground-based, diffraction-limited imaging spectroscopic observations of major astronomical significance, including imaging spectroscopy of protoplanetary disks and active galactic nuclei, and astrometric imaging of globular cluster cores; (2) to develop a new multi-aperture, wide-field interferometer that will record the field-angle and subaperture-dependent phase information required for diffraction-limited post-processed imaging spectroscopy; (3) achieving a deeper level of understanding of atmospheric turbulence, its optical consequences and correction; and (4) to develop an alternative approach to active correction (Adaptive Optics) that utilizes full post-processing.

摘要 马丁角 AST-9618811 该项目的目标是：（1）实现具有重大天文学意义的新的地面衍射限制成像光谱观测，包括原行星盘和活动星系核的成像光谱学，以及球状星团核心的天体测量成像;（2）研制新型多孔径，宽视场干涉仪，其将记录衍射限制后处理成像光谱所需的场角和子孔径相关相位信息;（3）实现对大气湍流、其光学后果和校正的更深层次的理解;（4）开发利用完整后处理的主动校正的替代方法（自适应光学）。
