The technological development which efficiently checks the huge infrastructure structure is urgent need. From several years ago, we have studied using a laser Doppler velocimeter capable of remote non-contact measurement in vibration measurement. However, a seal for retro-reflection is employed as a laser illumination target by LDV measurement, but installation is sometimes difficult. Furthermore, it is difficult to multi-directional vibration measurement at a single target for normal measurement. Therefore, in order to solve the problems described above in the present study, we examined the new vibration measurement using heterologous laser irradiation targets.
