Method of and aparatus for measuring the transverse moments of the electromagnetic field associated with an optical beam. |
| 摘要 |
<p>A method and an apparatus are provided wherein a light beam is passed through a slit (7) oscillating with respect to the beam, and a periodic signal is obtained from the beam portion traversing the slit and is split into its spectral components. Moment values are derived from the values of the amplitudes of such components.</p> |
