AOA Xinetics provides a wide range of electronics options for deformable mirrors. A high-speed driver provides performance over a broad range of operating conditions and requirements. The high source current insures operation into the 20 kHz bandwidth range. In contrast, the XiMux multiplexer electronics take advantage of the nearly perfect capacitor characteristics of PMN ceramic to provide an extremely compact, lower cost alternative. AOA Xinetics also offers a 1 to 10 channel driver system for low order systems, micropositioners, and/or individual actuators.

High-Speed Driver Electronics

The AOA Xinetics 9U Series Deformable Mirror Driver Assembly consists of a hierarchical assembly of 19" Rack Assemblies, 9U Eurocard chassis, and 9U x 400 mm printed wiring boards of two types: High Voltage Amplifiers (HVA) and Chassis Controller Cards. Each HVA incorporates the electronics to service 32 channels of mirror actuators. Each rack can support up to four chassis or a combination of power supplies and chassis. The larger systems use multiple rack assemblies. The AOA Xinetics drivers have a digital front end that uses a parallel interface, which can be connected to computers or reconstructors at rates up to 10 million bits/sec. A custom backplane maps the actuators to the zener protection arrays. Built-in-test diagnostic circuitry can be accessed through a second digital port to monitor mirror system health.

Low-Cost XiMux Multiplexer Driver Electronics

The deformable mirror multiplexer driver gives the end user a new lower-cost option for mirror electronics. By using multiplexer addressing schemes and the inherent properties of the AOA Xinetics PMN actuators, a lwo-bandwidth, low-cost system results. Data communication and control signals protocol simplicity gives this driver system bench-top-rights as building block for open loop or closed loop system configurations. The single package design can support up to four multiplexer driver boards each controlled by an individual data and cannoned channel. The end user has flexibility selecting a single multiplexer driver board dedicated package or a two to four multiplexer driver board package applicable for large single or multiple deformable applications.
