Description

technical field [0001] The invention relates to a detection device, in particular to a three-dimensional optical coherence elastography detection device applied to corneal refractive surgery. Background technique [0002] Optical coherence elastography is a technology that uses elastic parameters such as Young's modulus, shear modulus, stress and strain of soft tissue as the imaging object. With the development of optical coherence tomography (OCT), optical coherence elastography (OCE) has been favored by people due to its micron-level resolution, real-time image processing, and non-invasive imaging. For corneal refractive surgery, real-time image processing and analysis are required, so the use of optical coherence elastography is inevitable. [0003] At present, the convex lens is a common optical element in corneal refractive surgery. In order to better observe the image, it is necessary to test the light transmittance of the convex lens. When people test the light trans...
