The invention discloses a dynamic system multi-physics field imaging detection system which comprises a digital projection illuminating device. The digital projection illuminating device is arranged right in front of a measured vibration object, multi-spectral cameras are symmetrically arranged on the two sides of the digital projection illuminating device, and the surface of the measured vibration object radiates under the irradiation of the digital projection illuminating device. A synchronous sampling device controls the multi-spectral cameras to capture a radiance image of the measured vibration object at the same time, an image capture card is connected with the multi-spectral cameras to be used for collecting data and outputting the image data to an information storing device and an information processing system, the synchronous sampling device is connected to the information processing system, and the information processing system is a PC. According to the dynamic system multi-physics field imaging detection system, a digital projector is used for lighting, the synchronous sampling system is additionally arranged, so that measuring errors are reduced, and the measuring accuracy is improved; the wavelength measuring range is wide, a plurality of wavebands can be measured, the multiple physical quantities such as the vibration source temperature and the materials can be detected, and therefore the measuring reliability and the measuring precision are improved.
