Abstract

A vibrating pattern of interference fringes produces in a short-circuited photoconductor an ac current (nonsteady-state photoelectromotive force).1 This effect is highly promising for the highly sensitive adaptive detection of optical phase-modulated signals.2 The dynamics of the effect are usually determined by a process of dielectric (Maxwell) relaxation with a characteristic time τM inversely proportional to the average photoconductivity of the sample σ.1
