Working Principle of Two-Frequency Machine Shaking
The two-frequency machine shaking mechanism involves generating two slightly different laser frequencies within a ring-shaped optical cavity. These two frequencies interact to form a beat frequency, which is sensitive to rotational changes. This design mitigates mode locking and enhances measurement precision.
| Parameter | Traditional RLG | Two-Frequency Machine Shaking RLG |
|---|---|---|
| Bias Drift | 0.01°/hr | 0.001°/hr |
| Noise Level | 0.005°/√hr | 0.0005°/√hr |
| Stability | Good | Excellent |
| Application Range | Moderate | Wide (Aerospace & Military) |
JIoptics utilizes advanced optical components and vibration damping mechanisms to ensure the two-frequency RLG maintains exceptional performance under dynamic conditions.
