Example Embodiment
[0038] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings, and the preferred embodiments described herein are intended to illustrate and explain the present invention, and are not intended to limit the invention.
[0039] like figure 1 As shown, the OCT image reconstruction method based on non-uniform discrete Fourier transform is included in the present invention contains the following steps:
[0040] Step 1, place the mirror at the reference arm and the sample arm to adjust the interference signal in the OCT system. The light source is a broadband source that uses a fiber optic optical path system. Broadband light source reaches the reference arm and the sample arm after the coupler spectrophotometry, the reference arm is returned to light is a R Exp (IK · 2R), in the formula K is a wave number, 2R is the optical path of the reference arm, A R It is the reflection coefficient of reference light. At the sample ar...
