Abstract

We have designed a tip/tilt segmented mirror for the use in adaptive optics. The specific application that this device has been designed for, tracking a laser pulse through the sodium layer of our atmosphere, is well within the capabilities of this device. Through the use of finite element analysis simulations we have shown that the device has an operating voltage in the 100-150 V range, full mechanical stroke of 2.8&mgr;m, and is capable of reaching its full stroke in under 60&mgr;s. It also has shown good decoupling of the tip and tilt modes, allowing the device to track pulses that come in from any direction. Testing of the device has shown that there is a maximum of 22 percent error between the simulation and the testing results.
