论文摘要
Kalao是一种天然引导星自适应光学（AO）成像仪，该成像仪安装在智利拉西拉（La Silla）的120万Euler Swiss望远镜的第二个Nasmyth焦点上。该系统的初始设计是在Roboao上具有修改的Roboao启发，以便以自然导向星（NGS）模式运行。 Kalao的建立是通过跟进苔丝卫星调查的候选人来搜索星球上托管星星的二进制。光学设计针对450-900 nm波长范围进行了优化，并配备了SDSS \ emph {g，r，i，i，z}过滤器。该系统的设计用于波前控制，至$ i $ -magnitude 11星，以探测与径向速度仪器（如竖琴和NIRP）相同的参数空间。该系统的主要组件是11x11 10.9 cm子孔径乘以CCD（EMCCD）Shack-Hartmann Wavefront传感器，这是140个执行器微机械系统（MEMS）可变形的镜子，可变形的镜像，快速的尖端/倾斜镜子，图形处理镜子（GPU）的电图（GPU）式糖果胶质胶质胶质胶胶凉爽计算机计算机计算机计算机。它旨在以高达1.8kHz的速度运行，以便检测到150MAS可见光衍射极限的伴侣。实时自适应光学控制正在使用在GPU上运行的可可软件。如果取消了共同限制，该工具计划在2021年初在智利进行调试。
KalAO is a natural guide star adaptive optics (AO) imager to be installed on the second Nasmyth focus of the 1.2m Euler Swiss telescope in La Silla, Chile. The initial design of the system is inspired on RoboAO with modifications in order to operate in natural guide star (NGS) mode. KalAO was built to search for binarity in planet hosting stars by following-up candidates primarily from the TESS satellite survey. The optical design is optimised for the 450-900 nm wavelength range and is fitted with SDSS \emph{g,r,i,z} filters. The system is designed for wavefront control down to $I$-magnitude 11 stars in order to probe the same parameter space as radial velocity instruments such as HARPS and NIRPS. The principal components of the system are an 11x11 10.9 cm sub-apertures Electron Multiplying CCD (EMCCD) Shack-Hartmann wavefront sensor, a 140 actuators Microelectromechanical systems (MEMS) deformable mirror, a fast tip/tilt mirror, and a graphics processing unit (GPU) powered glycol cooled real-time computer. It is designed to run at up to 1.8kHz in order to detect companions as close as the 150mas visible-light diffraction limit. The real-time adaptive optics control is using the CACAO software running on GPUs. The instrument is planned for commissioning early 2021 in Chile if the covid restrictions are lifted.
