Most of the time the lasers are dark, producing areas of light with low intensities with the occasionally brief but brilliant flashes of high - intensitylight.
大部分的时间里激光是暗的，产生低强度的光区伴随着偶尔短暂的高强度光的闪烁。

These researchers were encoding digital data by varying the intensity of a pulse of light. For example, high intensity would represent a 1 and low intensity would represent a 0.
这些研究者通过改变光脉冲的强度来重编电码，比如，用高强度来表示1低强度来表示0。
