Optical coherence tomographic imaging system

Abstract

The invention discloses an optical coherence tomographic imaging system, which comprises an OCT (optical coherence tomography) infrared source reference arm, an acquisition portion and a detection arm. The detection arm is provided with optical fibers, a collimator, an optical path galvanometer scanning system, a lens and a heat mirror along an optical path from the OCT infrared source reference arm to human eyes, infrared emitted from the lens is reflected by the heat mirror to human eyes, a slit lamp system is arranged on an optical path opposite to the optical path from the heat mirror to the human eyes, and white light from the slit lamp system passes through the heat mirror to be emitted into the human eyes. The optical coherence tomographic imaging system combines slip lamps with OCT, the OCT system is independent relatively, and mutual imaging is unaffected and mutually supplementary. OCT imaging and slip lamp imaging share a common focus, so that fundus surface or anterior segment surface information and deep structural information can be obtained simultaneously without more adjustment. The optical coherence tomographic imaging system is more reasonable in structure and more stable in imaging.

Description

technical field [0001] The present invention relates to an optical device, in particular to an optical imaging device. Background technique [0002] Multifunctional imaging is the development trend of medical imaging technology. In the past ten years, the research of Optical Coherence Tomography (OCT) has made important progress. It uses the basic principle of weakly coherent light interferometer to detect the back reflection or Scattering signals can be scanned to obtain two-dimensional or three-dimensional high-resolution microstructure images of biological tissues, and the resolution can reach several to more than ten microns. Because optical coherence tomography can realize non-contact, non-invasive, high-resolution detection of eye diseases, it has been widely used clinically. However, the imaging range of optical coherence tomography is small, generally a few millimeters, and it is difficult to locate the diseased tissue, so other imaging methods are often needed for...

Problems solved by technology

However, the independence of the OCT system is not enough, and the lens and objective lens used are all on the slit lamp system, which leads to the decline of OCT imaging quality and the scope of application is also limited.
