When electrons or photons in a beam pass through the two slits, they act as waves and produce an interference pattern on the wall.
当一束电子或者光子通过这两条裂缝，他们就像波纹一样并产生互相干涉的图案。

If the two arms have identical lengths, then interference between the light beams returning to the beam splitter will direct all of the light back toward the laser.
如果两条边一样长，分光器发射的激光将被完全反射回分光器。

The Michelson interferometer system which has two-beaminterference is applied in Fourier Transform interferometer, the moving mirror could tilt in three directions in motion.
