Shooting system and test system for shooting flow field structure in wind tunnel test

The invention provides a shooting system and test system for shooting a flow field structure in a wind tunnel test. The shooting system comprises a multi-cavity sensor that is used for outputting a laser pulse to a wind tunnel test section to illuminate a flow field in the wind tunnel test section and enabling tracer particles in the flow field to emit scattered light and a shooting device for carrying exposure and imaging by using the scattered light to shoot a flow field structure. The multi-cavity laser includes a plurality of dual-cavity lasers that respectively output laser pulses with different wavelengths. The shooting device includes a plurality of cross-frame cameras corresponding to the dual-cavity lasers one by one; the input terminal of each cross-frame camera is provided witha light filter assembly filtering light with specific wavelengths; and the wavelength of light which can pass through the light filter assembly can is identical with the wavelength of the laser pulseoutputted by the correspon
