我们将介绍下一代近红外（0.84 - 2.45微米）成像仪和积分场摄谱仪（IFS）仪器，Liger，这是为W。M.凯克天文台。Liger成像仪和IFS同时在天空中运行，并经过优化以采样Keck全天空精密自适应光学（KAPA）系统。Liger IFS设计能够通过扩展到更蓝的波长覆盖范围、更大的视场和光谱分辨率范围来提供新的科学能力。我们将讨论整个Liger的技术设计，科学要求和整个计划的实施计划。
We will present the status of the next generation near-infrared (0.84 - 2.45 micron) imager and integral field spectrograph (IFS) instrument, Liger, that is being designed for the W. M. Keck Observatory. The Liger imager and IFS operates concurrently on-sky and are optimized to sample the Keck All-sky Precision Adaptive optics (KAPA) system. The Liger IFS design is able to offer new science capabilities by extending to bluer wavelength coverage, larger field of views, and range of spectral resolving powers. We will discuss the overall Liger technical design, science requirements, and implementation plans for the entire program.
