Summary
A new expansion of a general stationary stochastic optical field is derived. Each term of the series is seen to represent a recently defined new class of optical fields, the so-called spectrally quasifactorizable fields. Alternative expansion in terms of nonstationary fields that obey the wave equation is also shown. A relationship between temporal and spatial features of stationary free optical fields is discussed.
Riassunto
Si deriva un nuovo sviluppo di un campo ottico stocastico stazionario generale. Ogni termine della serie appare rappresentare una nuova classe recentemente definita di campi ottici, i cossiddetti campi spettralmente quasi fattorizzabili. Si mostra anche un’espansione alternativa in termini di campi non stazionari che obbediscono l’equazione d’onda. Si discute una, relazione tra comportamenti temporali e spaziali di campi ottici liberi stazionali.
Резюме
Предлагается новое разложение стационарных стохастических полей. Каждый член разложения представляет новыи класс оптических полей: так называемых спектрально квази-факторизуемых полей. Также показывается, что альтернативное разложение на основе нестационарных полей подчиняется волновому уравнению. Обсуждается связь между временными и пространственными характеристиками стационарных свободных полей.
