Abstract: Disclosed is a Brillouin-optical coherence tomography angiography (OCTA)-speckle multi-mode elastography system device, including a Brillouin-OCTA sample scanning unit, a Brillouin scattering elastography system, an OCTA system, a speckle detection system, and a time sequence controller. According to the present invention, advantages that the Brillouin scattering elastography system can perform high-resolution measurement on a bulk elasticity modulus, the OCTA system can perform high-resolution structure imaging, and the speckle detection system can perform wide-field blood flow velocity measurement are utilized to perform in-situ synchronous imaging on a blood vessel structure and elasticity distribution, and to quantify a blood flow velocity, so that scientific basis and technical support are provided for early diagnoses of clinical blood vessel diseases.
