Optical coherence tomography side lobe artifact suppression method and device

The invention discloses an optical coherence tomography sidelobe artifact suppression method and device, which can effectively solve the counterbalance between the axial resolution and the sidelobe suppression effect in a spectral domain method and do not need to carry out any measurement and calculation and priori estimation on the PSF of an OCT system. The method comprises the following steps: (1) constructing a multi-window reconstruction window function, and performing multi-window shaping on an acquired spectrum to prepare for subsequent iterative optimization; (2) establishing an OCT (Optical Coherence Tomography) spectrum resolving model oriented to a sidelobe suppression reconstruction task; (3) based on the solution model established in the step (2), introducing sparse continuous priori knowledge constraints, and generating a multispectral sparse continuous priori iterative optimization reconstruction method; (4) carrying out a reconstruction optimization calculation process based on prior constraint
