This Small Business Innovative Research (SBIR) Phase I project provides a significant advancement of the state of the art in fast, high-precision calibration and control of deformable mirrors for adaptive optics (AO)applications. This is accomplished by the development of a detailed nonlinear model of deformable mirror performance and fast solvers for the differential equations that describe the situation. Inverse techniques are utilized in the calibration process and fast solvers are used in the control. This approach provides enhanced performance over conventional approaches which assume that the deformable mirror is linear and only approximately solves the differential equations involved in two important ways. The first is that convergence in closed loop operation will be accelerated and the second is that accurate open loop control is available. The two major results of the proposed effort, accurate calibration and high-precision control of deformable mirrors, will be demonstrated by using the appropriate level of analysis and simulation. The team will concentrate in applying these advances to extra solar planet detection. The commercial impact of this work will be significant as it will facilitate the application of AO technology to areas that are unavailable today such as laser communications, biomedical imaging, consumer electronics, surveillance, and solar energy. Although the purpose of the proposed work is to bring this capability to market the scientific merits of this work are significant in their own right. Since this effort develops fast solvers to differential equations and solving an inverse problem that leads to the practical calibration and control of hardware there is little doubt these techniques have scientific merit and will be useful in these areas."This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)."

这项小型企业创新研究（SBIR）I阶段项目在快速，高精度校准和自适应光学镜像（AO）应用程序的可变形镜子的控制方面为最新技术提供了重大进步。这是通过开发详细的可变形镜像性能的非线性模型和描述情况的微分方程的快速求解器来实现的。在校准过程中使用了逆技术，并且在控件中使用快速求解器。这种方法在传统方法上提供了增强的性能，该方法假设可变形的镜像是线性的，并且只能以两种重要方式求解涉及的微分方程。第一个是闭环操作中的收敛性将加速，其次是准确的开路控制。提出的努力的两个主要结果，准确的校准和对可变形镜的高精度控制，将通过使用适当的分析和仿真来证明。该团队将专注于将这些进步应用于额外的太阳能行星检测。这项工作的商业影响将非常重要，因为它将促进AO技术在当今无法使用的领域中应用，例如激光通信，生物医学成像，消费电子，监视和太阳能。尽管拟议的工作的目的是使这种能力销售这项工作的科学优点本身具有重要意义。由于这种努力将快速求解器开发到微分方程并解决导致硬件的实际校准和控制的反问题，因此毫无疑问，这些技术具有科学优点，并且在这些领域将很有用。
