不同于通常的透镜通过衍射来压缩或者改变光的形态，时间透镜通过光的弥散放大或者压缩光波的时间。

Unlike a normal lens, which compresses or changes the actual shape of a light wave through diffraction, a time lens magnifies or compresses the time of a light wave through dispersion.

随后用激光穿过第一块透镜，导致两块透镜之间发生的时间周围的光产生弥散，随后光通过第二块时间透镜回到初始相位。

This dispersed the light around the events happening between the lenses. The light then passed through the second split time lens and returned to its original phase.

对于实际光学系统，由于光的衍射和像差，使所成的点像为一弥散斑。

However, for the actual optical system, its point image become a speckle because of diffraction of light and aberration.
