Abstract
The study describes sensors with an inclined grid de-signed to monitor the condition of structures installed on the bridge. The aim of the study is to study the possi-bility of using the developed sensors with an inclined grid to monitor the condition of structures by checking the deformation of various parts of bridges under highway loads, as well as comparing the characteristics of sensors with an inclined grid with conventional Bragg sensors. In this paper, experimental observations show that the results of using sensors with an inclined grid are in excellent agreement with the results obtained using conventional Bragg sensors. Also, a change in the wavelength of the VBR was detected and a comparison of the deformation characteristics for measuring tem-perature without deformation and the VBR for measur-ing deformation characteristics on a sensitive Bragg sensor for 700 seconds.
