Abstract
Disclosed is a Brillouin-optical coherence-speckle based multi-mode elasticity measurement device, including a Brillouin-optical coherence elastography common-path scanning unit, a Brillouin scattering elastography system, an optical coherence elastography system, a speckle elastography system, and a time sequence controller, where the Brillouin scattering elastography system and the optical coherence elastography system share the Brillouin-optical coherence elastography common-path scanning unit. According to the present invention, advantages that Brillouin scattering elastography can perform high-precision measurement on a bulk elasticity modulus, optical coherence elastography can rapidly obtain an elasticity distribution of an entire sample to perform three-dimensional elasticity mapping, and laser speckle elastography can perform wide-field elasticity measurement are utilized to perform in-situ synchronous imaging on elasticity distribution of lesion tissue, so that scientific basis and technical support are provided for early diagnosis of clinical diseases.
