HOERBIGER inside – Precision in space
When satellites transmit data via laser or space telescopes capture razor-sharp images, the highest level of precision is essential. Even the smallest vibrations or movements can cause a satellite’s laser to miss its target or images to become blurred.
To prevent this, tilt mirrors from PI (Physik Instrumente) provide fine alignment. As satellites travel through orbit at speeds of up to 28,000 km/h, these highly dynamic mirrors move through minute angles, correcting deviations in real time. This keeps laser beams precisely on course and stabilizes optical systems even under the demanding conditions of space. At the heart of the technology are piezoelectric drives, which can execute movements faster and more precisely than many conventional systems. They enable the highly accurate alignment of laser systems and telescopes in satellites and space missions. In this way, an almost invisible mirror becomes a critical building block for communication, navigation, and research in space.
