Description
Technical field
The present invention relates to field of medical device more particularly to a kind of big visual angle virtual reality optical systems of magnetic resonance compatible.
Background technique
Existing reflective magnetic resonance compatible visual stimulator visual field is small, to environment without isolation, can not provide right and left eyes point view
And stereopsis.
Existing direct-viewing type magnetic resonance compatible visual stimulator is as shown in Figure 1, include image transmission optical fibre 1, reflective prism 2, the
Two image transmission optical fibres 3, VR eyepiece 4, the end face figure like 11 of image transmission optical fibre 1 pass sequentially through reflective prism 2, the second image transmission optical fibre 3, VR mesh
Human eye 5 is reached after mirror 4；As it can be seen that direct-viewing type magnetic resonance compatible visual stimulator visible angle is small, visual field is small, and eyespot is closer, visual field
Diaphragm is small.
Above-mentioned apparatus cannot achieve the visual effect of the virtual reality under Magneti Resonant Condition.
Summary of the invention
The present invention is intended to provide a kind of big visual angle virtual reality optical system of magnetic resonance compatible, utilizes high resolution imaging curtain
Cloth enables the real image of big field optical imaging to be dispersed into multiple directions, electromagnetism of the examinate in the intracavitary complexity of magnetic resonance
It can be seen that wide-angle scene, realizes big visual angle under environment, has and the VR visual stimulus of right and left eyes point view and stereopsis is provided
System.
In order to achieve the above objectives, realization that the present invention adopts the following technical solutions:
The big visual angle virtual reality optical system of magnetic resonance compatible disclosed by the invention, including image transmission optical fibre and light path system,
The light path system is located at the front for going out light end of image transmission optical fibre, and the curtain for imaging is equipped in the light path system.
Preferably, the light path system includes enlarging lens and reflective mirror, and the enlarging lens are located at image transmission optical fibre and anti-
Between light microscopic, enlarging lens be located at image transmission optical fibre go out light end front and with image transmission optical fibre go out light rectify pair, it is described reflective
For the reflective surface of mirror towards the light-emitting surface of enlarging lens, reflective mirror is not parallel with enlarging lens, and the curtain is towards the anti-of reflective mirror
The reflective surface of smooth surface, curtain and reflective mirror is not parallel.
Further, the invention also includes VR eyepieces, and the VR eyepiece is parallel with curtain, the curtain be located at reflective mirror with
Between VR eyepiece.
Preferably, the angle of the reflective mirror and enlarging lens is 45 °, and the angle of the curtain and reflective mirror is 45 °, curtain
Cloth is vertical with enlarging lens.
Preferably, the curtain is yellow.
Preferably, the curtain is high resolution imaging curtain.
Preferably, the VR eyepiece is big field stop VR eyepiece.
The principle of the present invention is as follows: fiber end face image projects reflecting mirror after amplifying by enlarging lens, and reflecting mirror will
Amplifying lens group generates real image and projects curtain, and curtain scatters big field-of-view image in order to watch, using big field stop VR
Eyepiece amplifies observation to real image on curtain.
Beneficial effects of the present invention are as follows:
1, the present invention utilizes high resolution imaging curtain, and the real image of big field optical imaging is enable to be dispersed into multiple sides
To examinate is under the electromagnetic environment of the intracavitary complexity of magnetic resonance it can be seen that wide-angle scene, realizes big visual angle, have and mention
For the VR visual stimulus system of right and left eyes point view and stereopsis.
2, present invention employs enlarging lens amplifying fiber end face figure likes；
3, the present invention enables big field-of-view image to be observed using curtain, can accomplish visual field effect required by VR.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of direct-viewing type magnetic resonance compatible visual stimulator.
Fig. 2 is schematic structural view of the invention.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with attached drawing, to the present invention into
