Light splits into two beams when passing through a double refraction material.
证据在于，当两束光交叉照射时，它们不会相互影响。
For one thing, two beams of light that cross paths don't interact with each other at all.

这组人员设计了一个反射和干涉系统，将激光分成两束，分别对准抛光硅晶片的两面，将两束光限制在硅当中。
By splitting a laser beam and aiming each part onto opposite sides of a polished silicon wafer, the group engineered a system of reflection and interference that traps both beams in the silicon.

返回的两束光在分束器处汇合，产生由亮区和暗区组成的干涉图案，图案中，光波要么相互抵消要么相互增强。
The returning light beams merge together at the beam splitter and create an interference pattern of light and dark regions where the light waves either cancel out or reinforce each other.
