Abstract
A kind of optical coherence tomography system, is characterized in that comprising lasing light emitter (1), beam splitter (2), the first lens (3), reflecting mirror (5), clavate mirror (6), the 3rd lens (7), the 4th lens (8) and reference mirror (9).The optical resolution of optical coherence tomography system of the present utility model improves 5-10 doubly, solve the problem because lack of resolution causes subcellular fraction aspect organizational information to lack, clinical practice is more deep, wider, optical coherence tomography system of the present utility model provides clinical feasible submicron resolution OCT equipment, exceed the OCT equipment that on current world market, resolution is best, great development space will have been had clinically with on market.
Description
Technical field
This utility model relates to optics technical field of medical detection, especially a kind of optical coherence tomography system.
Background technology
Means of optical coherence tomography (OCT) is a kind of noninvasive, forms the optical image technology of high-resolution biological tissue profile with flank speed.Be mainly used in ophthalmology, skin, dentistry, vascular medical diagnosis and material Non-Destructive Testing, current clinical OCT equipment imaging and B ultrasonic similar, its spatial resolution (5-10 micron) exceeds 10 times than B ultrasonic, even so, such resolution is still not enough to discernable cell and subcellular structure, and therefore the organizational information information of a lot of cell and subcellular fraction aspect lack.
Summary of the invention
The purpose of this utility model is to provide a kind of optical coherence tomography system, doctors can diagnose ophthalmology and other diseases according to the in vivo image with cell and subcellular definition, improve diagnostic accuracy, reduce the number of times of biopsy sampling, alleviate patient's body and mind and financial burden.
The technical solution of the utility model is:
A kind of optical coherence tomography system, comprise lasing light emitter 1, beam splitter 2, first lens 3, reflecting mirror 5, clavate mirror 6, the 3rd lens 7, the 4th lens 8 and reference mirror 9, described lasing light emitter 1 is by Fiber connection to the first lens 3, first lens 3 opposite side is provided with beam splitter 2, beam splitter 2 side is provided with reflecting mirror 5, reflecting mirror 5 side is provided with clavate mirror 6, clavate mirror 6 two ends are respectively equipped with the 3rd lens 7 and the 4th lens 8, being reference mirror 9 outside 4th lens 8, is target acquisition region 11 outside the 3rd lens 7.
Described beam splitter 2 side is provided with the second lens 4, second lens 4 opposite side by Fiber connection to spectrogrph 10.
The beneficial effects of the utility model are:
The optical resolution of optical coherence tomography system of the present utility model improves 5-10 doubly, solve the problem because lack of resolution causes subcellular fraction aspect organizational information to lack, clinical practice is more deep, wider, optical coherence tomography system of the present utility model provides clinical feasible submicron resolution OCT equipment, exceed the OCT equipment that on current world market, resolution is best, great development space will have been had clinically with on market.

Fig. 1 is structural representation of the present utility model.
In figure: 1 be lasing light emitter, 2 be reflecting mirror, 6 be reference mirror for clavate mirror, 7 be the 3rd lens, 8 is the 4th lens, 9,10 be spectrogrph, 11 be target acquisition region for beam splitter, 3 to be the first lens, 4 be the second lens, 5.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further described:
As Fig. 1, a kind of optical coherence tomography system, comprise lasing light emitter 1, beam splitter 2, first lens 3, reflecting mirror 5, clavate mirror 6, the 3rd lens 7, the 4th lens 8 and reference mirror 9, described lasing light emitter 1 is by Fiber connection to the first lens 3, first lens 3 opposite side is provided with beam splitter 2, beam splitter 2 side is provided with reflecting mirror 5, reflecting mirror 5 side is provided with clavate mirror 6, clavate mirror 6 two ends are respectively equipped with the 3rd lens 7 and the 4th lens 8, being reference mirror 9 outside 4th lens 8, is target acquisition region 11 outside the 3rd lens 7.
Described beam splitter 2 side is provided with the second lens 4, second lens 4 opposite side by Fiber connection to spectrogrph 10.
The optical design of optical coherence tomography system of the present utility model is made up of 3 major parts: lasing light emitter, imaging control console and scan arm.The light that a super-radiance light emitting diode light source sends, by fiber guides to imaging control console.Light in optical fiber, through a collimating lens, 50/50 beam splitter and another condenser lens, is finally coupled in another optical fiber.From the light of light source, half is had to be delivered to scan arm from beam splitter.Light is returned from scan arm transmission, by a spatial filter, imports spectrogrph into.
Distance with reference to minute surface and light source can regulate, and just can produce interference when the optical path difference of two light paths is mated with the coherent wave appearance of light source, so the axial resolution of OCT is determined by the relevant wavelength of light source, is inversely proportional to the spectral bandwidth of light source.The lateral resolution of OCT is not only by the impact of wavelength, and pupil diameter and pixels across density are also important factor in order.
Vibration mirror scanning mirror, once be triggered, will produce another signal, triggers camera and takes pictures simultaneously.The software that we use also can from image pick-up card obtaining information.After snapshot clapped by camera, image pick-up card can import data into internal memory, can through fast Fourier transform before snapshot data imaging.
Embodiment recited above is only be described preferred implementation of the present utility model; not design of the present utility model and scope are limited; do not departing under this utility model design concept prerequisite; the various modification that in this area, common engineers and technicians make the technical solution of the utility model and improvement; all should fall into protection domain of the present utility model, the technology contents of this utility model request protection is all recorded in detail in the claims.
