Fig. 1 is a schematic view of the appearance structure of the present invention;
fig. 2 is a schematic diagram of an optical system according to the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.
According to the utility model discloses an embodiment provides a two mesh three-dimensional and confocal scanning eye ground cameras of laser.
As shown in fig. 1-2, according to the utility model discloses two mesh three-dimensional and confocal scanning eye ground cameras of laser, including body 1, body 1 openly is provided with imaging window 2, imaging window 2 is provided with eye-shade 3 outward, the left and right sides of 2 positions of imaging window is provided with an observation window 4 respectively, wherein, this internal two optical system that are provided with of body 1, 2 inside imaging optical system that are equipped with of imaging window are used for observing human eyes, near-far vision focusing and fundus image acquisition, and 4 inside observation windows that are equipped with two mesh stereovision optical system are used for observation and location to human eyes. The imaging optical system is sequentially provided with a mesh film objective lens 5, a hollow reflector 6, a focusing mirror group 7, a spectroscope 8, an imaging objective lens 9 and a CCD camera 10 from the imaging window 2 to the inside of the main body 1, wherein a light uniformizing mirror 11 is arranged below the hollow reflector 6, a light source 12 is arranged below the light uniformizing mirror 11, the light source 12 is an integrated module of a wide-spectrum xenon lamp and an infrared LED, and a xenon lamp flash lamp flashes at the moment of shooting. An imaging lens group 13 is arranged below the spectroscope 8, and an infrared camera 14 is arranged below the imaging lens group. The binocular stereoscopic vision optical system is provided with a hollow reflector 6, a focusing mirror group 7 and a CCD camera 10 from the observation window 4 to the inside of the main body, and an LED light source 15 is arranged below the hollow reflector 6. The hollow reflector 6 has a hole in the middle for light to pass through, the mirror surface for light reflection, the spectroscope 8 is a half-mirror with front for light reflection and back for light transmission.
Binocular stereoscopic principle: during operation, the LED light sources 15 of the two binocular stereoscopic vision optical systems reach the pupils through the hollow reflector 6, so that the illumination of the anterior segment of the eye is realized, the illuminated anterior segment of the eye sequentially passes through the hollow reflector 6 and the focusing lens group 7 to finally form an image on the CCD camera 10, the eyeground is imaged and calculated through the two binocular stereoscopic vision optical system lens groups and the CCD camera, and the determination of the front and rear distance dimensions can be realized in real time
The common imaging technology is that imaging is carried out through a light path, so that the dimensions of the image such as up, down, left and right can be determined, but the distance between the eye ground and the CCD camera cannot be determined because the eye ground and the CCD camera are on the same straight line.
Principle of confocal scanning: the common imaging technology is an image captured instantly when a focus is aligned to a certain position, which causes the image at the focus to be clear and the images at other positions to be relatively fuzzy, so that fundus images shot on a CCD camera are not clear enough. And then can carry out thorough comprehensive disease screening to the eye, and then guarantee the diagnostic effect of doctor to patient's eye disease, and then improve the treatment to patient's eye.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
