Reducing sample stage drift velocity

High-contrast imaging in transmission electron microscopes requires that thermal drift of the sample stage is minimised.


For this, the use of a Kalman filter strategy within the control structure of the stage has been investigated. A Kalman filter requires a thermal model of the stage construction, various inputs, and temperature measurements. In conjunction with a deformation model, this technique can compensate for drift. The compensation control strategy presented in this Mikroniek article has been validated using simulations based on multiple measurements.
