- It simply states that every point on a wavefront can be considered as a source of new spherical waves.
它簡單地指出,波陣面上的每一點都可以被視為新球面波的來源。

- Far away from the antennas, the waves join to form a wavefront that is a planar wave, kind of like ocean waves crashing on a shoreline.
在遠離天線的地方,波浪匯合成一個平面波的波陣面,有點像海浪拍打海岸線。
- Just as before, by continuously changing the timing of when each wave peak is emitted by each antenna, we can change the angle at which the wavefront is formed, essentially steering the beam in one direction or another.
和以前一樣,通過不斷改變每個天線發射每個波峰的時間,我們可以改變波面形成的角度,從而將光束轉向一個方向或另一個方向。

- Somewhere, it's like a status monitor, where we can see the status of the laser beacons, which are these four images we see up here, and also what commands are being sent to the deformable mirror to correct the wavefront.
- The lasers generate, like, a point source that we can measure with the wavefront sensor.
