In sinusoidal phase modulating laser diode interferometer, the main error source is the variation in output light intensity of light source.

在半导体激光正弦相位调制干涉仪中，光源输出光强的变化是测量误差的主要来源。

Nor is it possible simply to crank up the power of the source beam, because infra-red light at high intensity can cause eye damage.

他说，“多数光不会你想让它到哪它就到里”。 也不可能简单地增强光束的强度，因为高强度的红外光会伤害人眼。

Consequently, we adapt to use lamps as the main lighting source of the restaurant so the intensity of light can easily be adjusted.

从而，我们开始适应使用灯具作为我们餐厅的主要光源，这样一来，光照的强度能够很容易地进行调整。
