This can be accomplished using a beam splitter. 利用一個分束器就能完成上述過程。
One is the development of coherent beam splitters, which divide a beam of atoms into two beams. 其中一個是發展同調的分束器，它可以將一束原子分為兩束。
The unpolarized light from a lamp would be concentrated by a reflector and directed to a polarizing beam splitter. 燈發出的散射光將集中到一個反射面，並指向一偏振分光鏡。
Lenses can be placed between the beam splitter and the computer display to focus the image so that it appears at a comfortable viewing distance. 在分光鏡和電腦顯示器之間放幾個透鏡，即可調整影像的焦點，使它看起來像是隔著某個舒適的觀察距離。
