VR systems 110 include the first housing 111, eyepiece piece 112, the transmission microscope group 114, first of dichroscope 113, first
Refractive power speculum 115 and screen 116.
Wherein, eyepiece piece 112 is set in the first housing 111, and human eye is located at the side of eyepiece piece 112, dichroic
Mirror 113 is located at the other side of eyepiece piece 112, and dichroscope 113 is obliquely installed in the first housing 111, is used for infrared light
To external reflectance.First refractive power speculum 115, which is located at, transmits side of the microscope group far from dichroscope 113 for sending out screen 116
Light reflex to the first transmission microscope group 114, the first transmission microscope group 114 is set to dichroscope 113 far from eyepiece piece 112
Side.Human eye can be collected into the light that screen 116 is sent out, so as to see the content of the display of screen 116.Screen 116
The light sent out can pass sequentially through the first refractive power speculum 115, first and transmit microscope group 114, dichroscope 113 and eyepiece piece
112, eventually enter into human eye.
Specifically, the first transmission microscope group 114 includes the first planoconvex spotlight 117 and concave-convex lens 118, the first planoconvex spotlight
117 are set between dichroscope 113 and concave-convex lens 118.Side by side by the first planoconvex spotlight 117 and concave-convex lens 118
Being arranged can transmit the light that the first refractive power speculum 115 reflects well, can smoothly enter into human eye, realize that human eye can
Clearly see the content of the first refractive power speculum 115 reflection.
In the form of sheets, the minute surface of dichroscope 113 can be obliquely installed dichroscope 113 obliquely downward, can also direction
Oblique upper is obliquely installed, and imaging len 122 and camera body 123 are correspondingly arranged in the outlet of the light of the reflection of dichroscope 113
Place.Specifically, referring to Fig. 1, when the minute surface of dichroscope 113 tilts obliquely downward, imaging len 122 and camera body
123 are located at the bottom of the first housing 111.Referring to Fig. 2, when the minute surface of dichroscope 113 is tilted towards oblique upper, at
As lens 122 and camera body 123 are located at the second top of body.
It is worth noting that, dichroscope 113 not only reflects infrared light, it can be with reflective portion natural light.
Imaging system 120 includes the second housing 121, imaging len 122,124 and of the transmission microscope group of camera body 123, second
Second refractive power speculum 125.
The second housing 121 is for accommodating above-mentioned imaging len 122, the transmission microscope group 124 and second of camera body 123, second
Refractive power speculum 125, in the present embodiment, the second housing 121 is connect with the first housing 111, to realize that dichroscope 113 is anti-
The light shot out carries out collecting imaging.Specifically, the infrared light that imaging len 122 is used to reflect dichroscope 113 converges
To camera body 123.Second refractive power speculum 125 is located at imaging len 122 and second and transmits between microscope group 124 for will be at
As light that lens 122 collect reflexes to the second transmission microscope group 124, the second transmission microscope group 124 is located at the second refractive power speculum 125
Between camera body 123.Camera body 123 can take the image on human eye eyeground.
By the dichroscope 113 being arranged between the first transmission microscope group 114 and eyepiece piece 112, light is by two
When to Look mirror 113, most visible light-transmissives are gone, and infrared light and small part visible reflectance are returned, in this way, on screen 116
Content can still be seen by human eye, while infrared light can also the image on human eye eyeground spread out of come.
The light that dichroscope 113 reflects can be collected by the imaging len 122 of setting and be transferred to camera
Ontology 123, and then the image taking on human eye eyeground is got off, user oneself can see the image on oneself eyeground.Wherein, lead to
It crosses the second transmission microscope group 124 and the second refractive power speculum 125 is transmitted and reflected, to reduce the volume of the second housing 121.
Second transmission microscope group 124 includes that biconvex lens 126 and the second planoconvex spotlight 127, biconvex lens 126 are set to second
Between refractive power speculum 125 and the second planoconvex spotlight 127.Pass through being arranged side by side for biconvex lens 126 and the second planoconvex spotlight 127
The light that imaging len 122 collects can be transmitted well, can smoothly enter into camera.
Infrared illumination lamp 130 be set between the first housing 111 and the second housing 121 for dichroscope 113 into
The infrared light filling of row.Infrared illumination lamp 130 being capable of light filling, it is ensured that human eye can clearly see the content shown on screen 116.
In addition, the second housing 121 is additionally provided with the bluetooth transmission means and/or data-interface for being used for transmission image.Mobile phone
Both the image of bluetooth or data-interface transmission can also can be received, that is to say, that user can be certainly as ornamental amusement
Oneself sees the eye fundus image of oneself.
The present embodiment combines the ophthalmic medical equipment of popular VR products and profession, and professional equipment can be allowed to expand with rapid
The VR products of expansion enter household.
The operation principle of fundus camera 100 is：The light that screen 116 is sent out can by the first refractive power speculum 115,
First, which transmits microscope group 114, dichroscope 113 and eyepiece piece 112, enters human eye, and human eye can receive screen 116 and send out
Light so that human eye can see the content shown on screen 116 clearly.For light when by dichroscope 113, the overwhelming majority can
Light-exposed penetrate is gone, and infrared light and small part visible reflectance are returned, in this way, the content on screen 116 can still be seen by human eye
It arrives, while infrared light can also spread out of the image on human eye eyeground to come.It can be by dichroscope by the imaging len 122 of setting
The light of 113 reflections is collected and is transferred to camera body 123, and then the image taking on human eye eyeground is got off, user
It oneself can see the image on oneself eyeground.
In conclusion in fundus camera 100 provided by the invention, human eye can receive the light that screen 116 is sent out
And then human eye can see the content shown on screen 116 clearly.For light when by dichroscope 113, most visible lights are saturating
Past, infrared light and small part visible reflectance are returned, in this way, the content on screen 116 can still be seen by human eye, simultaneously
Infrared light can also spread out of the image on human eye eyeground to come.Dichroscope 113 can be reflected by the imaging len 122 of setting
Light is collected and is transferred to camera body 123, and then the image taking on human eye eyeground is got off, and user oneself can see
To the image on oneself eyeground.
In addition, the embodiment of the present invention additionally provides a kind of virtual reality imaging device comprising above-mentioned fundus camera
100, the image in human eye can be showed.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, any made by repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
