Free-space optical communication (FSOC) enables high-data-rate intersatellite links in low Earth orbit (LEO) constellations. Achieving stable optical connections under dynamic orbital conditions requires highly precise beam control. A recent development project required a space-qualified fast steering mirror for use in FSO terminals that would also be suitable for high-volume production. The goal was to ensure reliable optical link stability while complying with stringent requirements regarding mass, mechanical footprint, environmental robustness, and scalability. Read more
