The invention discloses a coaxial ultra-high-speed multi-sequence laser shadow imaging device which comprises a multi-cavity light source system, an optical fiber coupling system, a parallel light transmission imaging system, an imaging system, a data acquisition system and a control system. The multi-cavity light source shares one light path outlet, laser beams of different sequences share one imaging light path to enter the parallel light transmission device and the imaging light splitting device, and the light sensing time and the laser flash time of the camera are synchronous, so that the optical axis and the light path structure of imaging of different sequences can be consistent; and the same test area is imaged, the background quality of imaging light spots can be kept consistent, and multi-sequence imaging of an ultra-high-speed phenomenon is realized. 本发明公开了一种同轴超高速多序列激光阴影成像装置，包括：多腔光源系统、光纤耦合系统、平行光透射成像系统、成像系统、数据采集系统和控制系统。本发明通过采用多腔光源共用一个光路出口，不同序列的激光束共用一套成像光路进入平行光透射装置和成像分光装置，通过相机的感光时间和激光闪光时间同步，能够实现不同序列成像
