Description
Technical field
The present invention relates to a kind of ophthalmic camera for shooting anterior chamber of eye, specifically, the present invention relates to a kind of shines
The flash lamp light of camera is coupled in the light beam of crack and goes to shoot the ophthalmic camera of anterior chamber of eye.
Background technology
Slit-lamp microscope is mainly used in oculist office and checks anterior chamber of eye, including cornea, anterior chamber, iris and crystalline
Body.Then can be used to shoot and record the image of anterior chamber of eye as being equipped with camera.Become more and more popular with high-definition digital camera, more
More favored, slit lamp photography has become a big event of slit lamp examination.With internet and mobile phone remote doctor
Treat the popularization of concept, slit-lamp camera is just becoming the general inspection of examination and the strong tools of slit-lamp image management.
Generally, structural fracture lamp camera has two kinds of approach: has or not synchronous with camera flash lamp.It is being furnished with
In the approach of flash lamp, slit lamp photography machine is typically mounted in slit-lamp microscope, by optical splitter from microscopical observation
Light path is producing an image strip path.Therefore, camera can be taken a picture by this extra image strip path, with
When without interference with slit-lamp microscope normal use.Do not have in the approach of flash lamp, an available special adapter will split
Gap lamp camera is connected on microscopical eyepiece.This is simple to connect that make to become using the intelligent camera of low price can
Energy.
Shoot high-quality crack photo it is necessary to the white light source of a high brightness is producing bright and narrow splitting
Gap illuminates.The white light source of this high brightness is common in the flash lamp of photograph, and this special standby flash lamp needs and takes a picture
Machine synchronously uses.As a rule, the slit lamp photography machine being furnished with special standby flash lamp is expensive, and carrying charge can be shown with slit-lamp
The price of micro mirror itself is suitable.
On the other hand, most commercial digital cameras are all equipped with built-in flash.Particularly inexpensive and handy is stupid
Camera on melon type camera and cell phone is each equipped with embedded flash lamp, but they are usually not configured to
Drive the hot shoe seat of external flashing lamp.Therefore, the necessary embedded flash lamp by camera provides crack illumination for shooting.
Another factor to be considered of slit lamp photography machine is throughput, that is, the thang-kng effect in picture shooting path
Rate.Under normal circumstances, slit lamp photography machine passes through slit-lamp microscope shooting image, and this complicated facilities for observation can not be kept away
Exempt from there is larger light intensity loss.For the application only needing digital slit-lamp image to check without micro- sem observation, for example
Include the general inspection of examination of Telemedicine System, being then more likely to use does not have microscopical slit lamp photography machine.
Therefore, for examination general inspection and tele-medicine health system for, popularization slit lamp photography machine be very necessary
's.Whether the slit lamp photography machine for this purpose more stresses easy to use, competitively priced, accessible wireless network, and join
Standby microexamination is not but always too important.

Just receive the light 24 from flash lamp 23.Photoconductive tube adapter 25 is optical-mechanical components, when slit-lamp 32 is from instrument
When the side of axle 11 moves to opposite side, this optic-mechanical part can ensure that constant optical coupling.
In coupling flash lamp light the 24 to the second illuminating bundle 36 can also by other kinds of photoconduction such as fibre bundle or
Photoconductive tube.Assume to use fibre bundle, the first end of fibre bundle receives the light 24 from flash lamp 23, is connected to slit of illumination
Second end of beam generator 32 generates the second illuminating bundle 36 by adapter 39.The second illumination light in the second embodiment
Bundle 36, flash lamp 23 and fibre bundle are together as the second lighting source and synchronous with the flash lamp 23 of point-and-shoot camera 20.
Micro-lens 17 is located at the front end of point-and-shoot camera 20, the preferably achromatism of about 60 millimeters to 100 millimeters of focal length
Lens, are conventionally positioned at the position apart from 2 one focal lengths of working face.The for example same slit-lamp microscope of the function of micro-lens 17
Object lens, anterior chamber of eye 4-7 is imaged on position away from point-and-shoot camera 20 so that point-and-shoot camera 20 is focused simultaneously
Shot at a distance.In this way, the optical zoom of camera gun 22 continuously can be continuously regulated to the visual field and manages most
The state thought, makes the image-region that eyes 10 are selected fill up camera display.The pixel of camera and display screen therefore can be optimized
Resolution ratio.
Micro-lens 17 and the combination of camera gun optical zoom 22, there is provided a kind of micro- similar to conventional slit-lamp
The light multiplying power of mirror.In such analogy, similar to object lens, optical zoom is similar to microscopical magnifying glass rank for micro-lens 17
Section.Additionally, passing through micro-lens 17, when point-and-shoot camera 20 is anterior chamber of eye 4-7 to be carried out shooting characteristic in normal mode,
And show more reliable auto-focusing ability.So, point-and-shoot camera 20 need focus on and are produced by micro-lens 17
Range image.Therefore, when the anterior chamber of eye 4-7 to eyes 1 carries out feature shooting, external micro-lens 17 can make point-and-shoot take a picture
Machine 20 works in the normal mode rather than under macro mode.
Fig. 2 shows another slit lamp photography machine 200, and point-and-shoot camera 20 is arranged on slit-lamp microscope 10 by it
On, wherein, the flash light 24 of lamp of point-and-shoot camera 20 is coupled in crack light beam 30, with for shooting eyes 1
Anterior chamber of eye 4-7.Slit lamp photography machine 200 is mainly by a crack beam projector 32, point-and-shoot camera 20, photoconductive tube
60, microscope 10, and a camera adapter 26 forms.
In preferred version shown in Fig. 2, crack beam projector 32, point-and-shoot camera 20 and photoconductive tube 60 can be found in
Identical element in Fig. 1.Microscope 10 refers to any microscope of conventional slit-lamp microscope or portable slit-lamp microscope.Aobvious
Micro mirror 10 includes a micro objective mirror body 15, objective lens 12, and left eyepiece 13, right eyepiece 14.Camera adapter 26 is
Connect point-and-shoot camera 20 on microscope ocular 14.The selection of point-and-shoot camera 20 and be connected to microscope ocular 14 and be
Well-known to those skilled in the art.
Fig. 3 shows another slit lamp photography 300, and it adopts one to amplify mirror element 50 and cell phone cameras 40, hand
