OCT endoscopic imaging probe and manufacturing method thereof

Abstract

The invention provides an OCT endoscopic imaging probe. The OCT endoscopic imaging probe comprises a self-focusing optical fiber, wherein a spherical lens is connected to the light-outgoing end of the self-focusing optical fiber, a reflecting surface and a light-outgoing window corresponding to the reflecting surface are arranged on the spherical lens, light emitted from the self-focusing optical fiber is projected through the light-outgoing window under the reflecting effect of the reflecting surface, and the reflecting surface and the light-outgoing window are planes. The invention further provides a manufacturing method of the OCT endoscopic imaging probe. The OCT endoscopic imaging probe has the beneficial effects that the focusing of light can be optimized, the signal attenuation can be avoided, and the firmness of the probe is enhanced.

Description

technical field

[0001] The invention relates to a probe, in particular to an OCT endoscopic imaging probe and a manufacturing method thereof. Background technique

[0002] Optical coherence tomography (Optical Coherence Tomography, OCT) uses near-infrared light and the principle of optical interference to detect the back reflection or several scattering signals of incident near-infrared light at different depths of biological tissues. Through scanning, it can be obtained Two-dimensional or three-dimensional structural images of biological tissues. In recent years, although it has been found that it has the advantages of non-destructive and high resolution in vascular imaging and intracavitary tissue (stomach) examination, it is difficult to achieve large-scale application due to problems such as complex manufacturing process and poor imaging effect.

[0003] At present, most OCT probes on the market adopt the following two implementation methods:

[0004] One is to bond gl...
