description: The scientific work is devoted to interrogation of a fiber Bragg grating by a smartphone. A literature review was conducted and various methods of interrogation of fiber optic sensors by a smartphone were examined. The interrogation of a fiber Bragg grating by a smartphone was done, to the best of our knowledge, for the first time. The sensor interrogation system was assembled and calibrated. The polling system for polling consists of a smartphone and inexpensive off-the-shelf components: a piece of DVD, an optical slit made of two halves of a razor blade, and a case printed on a 3D printer. The smartphoneâs LED flashlight was used as the light source, and the spectra of the fiber Bragg grating were detected using the smartphoneâs camera and the diffraction grating based on the DVD. The fiber Bragg grating was recorded in a multimode fiber, the ends of which are connected to the camera and LED. The operation of the interrogation system of the fiber Bragg grating using a smartphone was demonstrated by an experiment on stretching of the fiber Bragg grating caused by the applied longitudinal force. The differences between measurements made using this system and a commercial spectrometer are about 1%, which indicates successful work.
