This can be accomplished using a beam splitter. 利用一個(gè)分束器就能完成上述過(guò)程。
One is the development of coherent beam splitters, which divide a beam of atoms into two beams. 其中一個(gè)是發(fā)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(fā)出的散射光將集中到一個(gè)反射面，并指向一偏振分光鏡。
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(gè)透鏡，即可調整影像的焦點(diǎn)，使它看起來(lái)像是隔著(zhù)某個(gè)舒適的觀(guān)察距離。
