Albert Abraham Michelsoni 1887. a disainitud seade, mis tekitab valguse interferentsipildi olukorras, kus valgusallikas jagatakse kiirejaguri abil kaheks haruks ja need mõlemad valguskiired peegelduvad tagasi kiirejaguri poole, mis seejärel ühendab nende amplituudid superpositsiooniprintsiibi abil ning saadud interferentsipilt suunatakse tavaliselt mingit tüüpi fotoelektrilisele detektorile või kaamerale, device designed by Albert Abraham Michelson in 1887 that produces an optical interference pattern; in this setup, a light source is split into two paths by a beamsplitter, and both light beams are reflected back toward the beamsplitter, which then combines their amplitudes according to the principle of superposition, with the resulting interference pattern typically being directed onto some type of photoelectric detector or camera
