Fast steering mirror system: a sharp tool for controlling beam direction with high precision

First, the working principle of the rapid steering mirror system

The rapid steering mirror system uses four voice coil actuators to provide fast, high-bandwidth rotation, while push-pull paired actuators provide smooth, even torque to the mirrors. An internal optics-based feedback loop provides positional feedback for accurate, stable pointing and tracking. The included controller/driver creates a feedback interface between the Angle sensor and the driver to provide current to the voice coil that tilts the mirror assembly. It also provides a convenient interface between the user and the mirror, allowing control voltage to be applied and mirror position to be monitored.

Second, the characteristics of the rapid steering mirror system

1. High precision: The fast steering mirror system uses an internal optically based feedback loop, which can achieve bi-axial high-bandwidth rotation with sub-micro resolution and has very high accuracy.

2. High reliability: The rapid steering mirror system uses a unique bending design to limit the movement of the mirror, thus eliminating the bearing surface often used in galvanometer scanners. This design allows for ultra-smooth motion, very high accuracy, and almost unlimited service life.

3. High performance: The fast steering mirror system uses four voice coil actuators to provide fast, high-bandwidth rotation, while the push-pull pair of actuators provides smooth, uniform torque to the mirror, which is characterized by high performance.

Third, the application scenario of the rapid steering mirror system

The rapid steering mirror system can be used for commercial purposes such as stabilizing laser beams, laser aiming, tracking, and stabilizing images. In laser processing, laser cutting, laser marking and other fields, the rapid steering mirror system also has a wide range of applications. In addition, in scientific research, medical equipment, aerospace and other fields, the rapid steering mirror system also has important application value.

In short, the fast steering mirror system is a high performance, high precision, high reliability equipment for a variety of applications requiring fast and accurate control of the direction of the beam.
