Feed-forward vibration compensation for small telescopes [PDF]

Advances in Optical and Mechanical Technologies for Telescopes and Instrumentation V, 2022
This publication investigates the applicability of feed-forward vibration compensation for small telescope systems in one axis, based on commercial-off-the-shelf accelerometers and a fast-steering mirror (FSM). The vibrations are measured with multiple accelerometers and their influence onto the optical path is reconstructed using a highpass filtered ...

Digital PWM controller with feed-forward compensation

Nineteenth Annual IEEE Applied Power Electronics Conference and Exposition, 2004. APEC '04., 2004
This paper describes a complete digital PWM controller IC with feed-forward compensation of the input voltage. The feed-forward compensation is accomplished through a delay-line digital pulse-width modulator (DPWM) where the cell delay is made inversely proportional to the input voltage.

Demonstration of a feed-forward PMD compensation technique

IEEE Photonics Technology Letters, 2002
We demonstrate a feed-forward technique, which characterizes first-order polarization-mode dispersion (PMD) and aligns it to a compensator. With appropriate components, the system could perform real-time compensation of first-order PMD with rapidly varying principal states of polarizations.
