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.

Abstract: Disclosed is a linear array scanning Brillouin scattering elastic imaging device. In the device, a signal generating system consists of a narrow linewidth continuous wave laser, a half-wave plate, a beam expander, a Y-direction scanning galvanometer, a microlens array, a pinhole array filter, a first plano-convex lens, a polarization beam splitter, a quarter-wave plate and a microscope objective. A signal receiving system consists of a microscope objective, a quarter-wave plate, a polarization beam splitter and an eight-channel optical collimator array. Each channel of an eight-channel spectrometer consists of an optical collimator, a convex lens, a scanning Fabry-Perot interferometer, a photomultiplier tube and an eight-channel photon collection card.
