The Hard X-Ray Nanoprobe

Hard X-Ray Nanoprobe, the laser decoder, and the piezo controller.

It’s extremely sensitive to operation conditions (noise, vibration, hysteresis, etc). However, we want the instrument to be robust and give us repeatable and reliable measurements.

The Plan

July 8, 2010 2

Decoding

LabView & Matlab

Decode the LDDM processor

unit signal and reconstruct the position.

Identify and model the

dynamics of the existing system

Implement a control system

and quantify the performance.

GOAL: Develop a new control algorithm to precisely control the nanoprobe motion.
