Paper Abstract

In this work, we offer a method of a field formation with given spatial features at the output of multimode fiber sensors using interference phenomena. Then method consists of a field two-stage correlation transformation at a fiber output. Transformation is realized by a phase modulator and a hologram. The developed method is practically realized in the fiber Doppler anemometer and vibrometer scheme. Features of sensors are discussed in this work.
