| 内容記述 | Extremely Large ground based Telescopes (ELTs), with apertures between 25 and 100m, are now being seriously studied by a number of groups. These proposals have several majortechnological barriers to overcome, but it seems probable that on the same timescale as spacemissions such as NGST and HII/L2 (approximately 2010) one or more such telescopes may bebecoming operational. Their performance, with atmospheric seeing correction by multi-conjugateadaptive optics (MCAO), will make themdominant in sensitivity for both imaging and spectroscopyfor 1 < λ < 2.5 μm and, in the larger apertures being considered, competitive in sensitivity forspectroscopy with resolution R ≧ 10,000 in the atmospheric windows at λ = 3-4, 8-13 and 20μm.At all these wavelengths ELTs would have angular resolution far superior to that offered by anyalternative facilities yet proposed. | |||||||
