Ferro-fluid mirror with shape determined in part by an inhomogeneous magnetic field |
| 摘要 |
A controllable optical mirror system incorporating a ferro-fluid having a surface which acquires an equilibrium shape in response to a gravitational field, rotational motion, and applied magnetic fields. The magnetic field has a predetermined spatial variation which produces an advantageous optical shape in the ferro-fluid surface.
