But instead of taking a single path, light can bend around the object in one of two, or four different routes, thus doubling or quadrupling the amount of information scientists receive.
但是光并非只走一条路径，而是可以从两个或四个不同路径中的一个绕过物体，这样科学家可以获得两倍或四倍的信息量。
The resolution of the laser interferometer is improved by using optical path difference doubling technique.
