Achieving the ambitious science goals for ELTs will rely heavily on the successful implementation of adaptive optical systems delivering very high order correction over substantial angular fields. Our aim is to build on our successful development of a unique hardware-accelerated AO simulation code to develop tools that are capable of accurately and rapidly modelling full-scale ELT-scale AO systems. For an ELT, the AO system must coordinate with system-wide control loops encompassing both the telescope and instrument systems. The traditional approach of combining independent error budgets for different parts of the telescope/instrument system will not be viable for an ELT. For example, the interaction between the active optics (aO) and adaptive optics (AO) control systems will be complex and will form an integral part of the telescope control system. Realistic modeling of AO for ELTs must therefore involve integration with models of the telescope and active optics systems and in many cases with the science instrument itself. Hence a key part of the modelling programme will be to create efficient interfaces to other components of 'end-to-end' ELT simulation, via in-house development and through collaboration with the relevant external groups. The goal will be to create models that can determine the parameters of a complete telescope + AO system + instrument package to meet specific scientific performance goals. The availability of such facilities will greatly enhance the UK's position with respect to the design and development of instrumentation for ELTs.

实现ELT的雄心勃勃的科学目标将在很大程度上依赖于成功实施自适应光学系统，从而在实质性角度上提供非常高阶的校正。我们的目的是建立在我们成功开发独特的硬件AO模拟代码的基础上，以开发能够准确，快速地建模全尺度ELT尺度AO系统的工具。对于ELT，AO系统必须与系统范围的控制循环进行协调，该环路包括望远镜和仪器系统。结合望远镜/仪器系统不同部分的独立错误预算的传统方法对于ELT不可行。例如，活动光学（AO）和自适应光学（AO）控制系统之间的相互作用将很复杂，并且将形成望远镜控制系统的组成部分。因此，针对ELT的AO的现实建模必须涉及与望远镜和主动光学系统模型以及在许多情况下与科学工具本身的集成。因此，建模程序的关键部分是通过内部开发以及通过与相关外部组的协作来为“端到端” ELT仿真的其他组件创建有效的接口。目标是创建可以确定完整望远镜 + AO System +仪器软件包的参数以实现特定科学性能目标的模型。此类设施的可用性将大大提高英国在ELT仪器的设计和开发方面的立场。
