Abstract

The invention discloses an optical coherence tomography-based phase calibration method, which comprises the following steps of 1, acquiring a relationship I-n between spectrum intensity I of a space n and a pixel number n by virtue of a charge-coupled device; 2, acquiring a relationship k-n between the pixel number n of the charge-coupled device and a wave number k; 3, performing interpolation operation on the relationship I-n between the spectrum intensity of the space n and the pixel number n to obtain a relationship I-k between the spectrum intensity of a space k and the wave number k.

Description

Technical field [0001] The present invention relates to the field of imaging detection technology, in particular to a phase calibration method based on optical coherence tomography technology. Background technique [0002] Optical coherence tomography (Optical Coherence Tomography, OCT) technology was first proposed in the 1990s. It has the advantages of non-contact, non-invasive, high resolution, and fast imaging speed. It has advantages in biomedical research and clinical diagnosis. Wide range of applications. [0003] In OCT, the original spectrum collected by a charge-coupled device (CCD) is uniformly distributed with respect to the pixel n of the CCD, while the subsequent data processing requires a uniformly distributed spectrum with respect to the wave number k. For this reason, phase determination is required. Mark, transform the interference spectrum from n-space (I~n) to k-space (I~k). [0004] The traditional phase calibration method uses the calibration lamp to understan...
