An optimized calibration strategy for high order adaptive optics systems : the Slope-Oriented Hadamard Actuation
نویسندگان
چکیده
The correct calibration of the interaction matrix D deeply affects the performance of an adaptive optics system. In the case of high-order systems, when the number of mirror modes is worth a few thousands, the actuation strategy is critical. This is a very first draft of a future paper, so feel free to contact the corresponding author for more accurate and up to date information.

The Slope-Oriented Hadamard scheme for in-lab or on-sky interaction matrix calibration
The correct calibration of the interaction matrix affects the performance of an adaptive optics system. In the case of high-order systems, when the number of mirror modes is worth a few thousands, the calibration strategy is critical to reach the maximum interaction matrix quality in the minimum time. This is all the more true for the E-ELT, for which on sky calibration procedures have to be co...
متن کاملMultichannel-Hadamard calibration of high-order adaptive optics systems.
we present a novel technique of calibrating the interaction matrix for high-order adaptive optics systems, called the multichannel-Hadamard method. In this method, the deformable mirror actuators are firstly divided into a series of channels according to their coupling relationship, and then the voltage-oriented Hadamard method is applied to these channels. Taking the 595-element adaptive optic...
متن کاملAdaptive Voltage-based Control of Direct-drive Robots Driven by Permanent Magnet Synchronous Motors
Tracking control of the direct-drive robot manipulators in high-speed is a challenging problem. The Coriolis and centrifugal torques become dominant in the high-speed motion control. The dynamical model of the robotic system including the robot manipulator and actuators is highly nonlinear, heavily coupled, uncertain and computationally extensive in non-companion form. In order to overcome thes...
متن کاملOptimized actuators for ultrathin deformable primary mirrors.
A novel design and selection scheme for surface-parallel actuators for ultrathin, lightweight mirrors is presented. The actuation system consists of electrodes printed on a continuous layer of piezoelectric material bonded to an optical-quality substrate. The electrodes provide almost full coverage of the piezoelectric layer, in order to maximize the amount of active material that is available ...
متن کاملCharacterization of Contour Shapes Achievable with a MEMS Deformable Mirror
An important consideration in the design of an adaptive optics controller is the range of physical shapes required by the DM to compensate the existing aberrations. Conversely, if the range of surface shapes achievable with a DM is known, its suitability for a particular AO application can be determined. In this paper, we characterize one MEMS DM that was recently developed for vision science a...
