In this paper, a multi-channel high-rate laser displacement sensor system accompanied with an open-source data acquisition software for structural health monitoring was explained. Hardware part of the system composed of three laser triangulation sensors with a resolution of 0.1 mm and a measurement acquisition rate at 70 Hz each. The software part is developed under Python open-source environment and handles initiation of data acquisition, data synchronization and data logging. The developed system was tested for reliability using a free vibration of a three-story model with a set of shaking-table tests and results are presented.
