Embodiment 1
[0062] In this embodiment, the samples are outer skin, cerebral cortex, and cornea, etc. There is no lens-like medium between the sample to be imaged and the imaging lens, and a focusing imaging lens is selected; at this time, the corresponding samples of different sample arm branches are in At different positions in the horizontal direction, the beam penetration depth of each sample arm branch is the same, and the optical path difference between each sample arm branch and the reference arm is different; different sample arm branches correspond to different OCT interference signal frequency segments , do not cross each other.
[0063] like image 3As shown, the sample arm includes a collimator, an optical field modulation module, a first and a second polarizing beam splitter, a first to a third Faraday rotator, a 1 / 4 glass slide, a first and a second mirror and a three-way Sample arm branch; the second port of the universal fiber coupler is connected to the collimator of the ...
Embodiment 2
[0068] In this embodiment, the sample is the eye, and among the three sample arm branches, the first and third sample arm branches are the optical path of the posterior segment of the eye, and the second sample arm branch is the optical path of the anterior segment of the eye; when imaging the posterior segment of the eye , there is a lens-like medium between the sample and the imaging lens, so the imaging lens of the posterior segment optical path adopts a 4F imaging lens. When imaging the anterior segment, there is no lens-like medium between the sample and the imaging lens, so the optical path of the anterior segment The imaging lens adopts focusing imaging lens; the optical path of the anterior segment coincides with the optical axis of the eye; the angle between the first optical path of the posterior segment and the optical axis of the eye is 10°~40°; the optical path of the second posterior segment and the optical axis of the eye The included angle is preferably -10°~-40...
