Usage of diffractive optical elements (DOEs) in fiber sensors is rather promising. This work is dedicated to the investigation of dependence of transverse mode spectrum in fibers with the step-like refractive profile on the micro bending value by means of the diffractive optical elements. Description of an experimental setup is provided here as well as methods of the experimental data processing allowing to have accurate measurements of the mode power. Dependence ofthe LP mode power on the fiber micro bending value is received. The received results allow expecting to design fiber sensors with advanced characteristics-dynamic range and accuracy.
