Abstract
The utility model relates to a beam-splitting structure of a digital pathological section scanner. The beam-splitting structure comprises a light source, an objective lens, a polarization splitting prism, a surface camera, and a linear camera, wherein the light source, the objective lens, the polarization splitting prism, the surface camera, and the linear camera are arranged on a support; and an incident light surface, a first polarized light surface and a second polarized light surface are arranged on the polarization splitting prism. The lights emitted by the light source enter the incident light surface of the polarization splitting prism through the objective lens and are respectively irradiated into the surface camera by the first polarized light surface of the polarization splitting prism and the linear camera by the second polarized light surface of the polarization splitting prism. According to the beam-splitting structure of the digital pathological section scanner provided by the utility model, the polarization splitting prism is used to split the incident lights into two beams of the lights, wherein one beam of the lights are used for scanning of the linear camera and the other beam of the lights are used for scanning of the surface camera, so that the surface camera and the linear camera can use the light source independently. And the operation personnel can select to use different camera modes according to different actual demands. To be specific, the surface camera can be used to carry out real-time global observation and the linear camera can be used to scan a picture rapidly, so that the application range of the digital scanner is widened.
Description
Technical field
The utility model relates to a kind of beam-splitting structure, relates in particular to a kind of beam-splitting structure of digital pathological section scanner.
Background technology
Optical microscope has been applied in every medical diagnosis and the scientific experiment research very early as a kind of exploration microworld strong tool.In recent years, along with the fast development of Computer Processing technology and image processing techniques, technology such as obtaining automatically of the online control of microscope, micro-image had been realized.Numeral pathological section scanner also is born thereupon.
Two kinds in the scanning camera separated time camera of numeral pathological section scanner and face camera.Its center line camera is once to obtain the image that pixel is wide, and the face camera is an image that once obtains the fixed pixel width, the synthetic complete figure of final all splicing seams; Adopt the line camera in the existing scanner or the face of employing camera comes scan slice.
Before invention the utility model, the inventor finds that there is following shortcoming in digital pathological section scanner of the prior art:
1, tradition is taked the scanner of line camera scanning, compares with the scanning of face camera, though more clear to the sectioning image of scanning, speed is also faster, need it to finish all scanning works after, just can observe and other operations digital slices;
2, the scanner of traditional employing face camera scanning is compared with the scanning of line camera, watches though can control in real time as conventional microscope, and the speed of making the digital scanning figure that cuts into slices is slower, and sharpness is also slightly inferior.
Therefore those skilled in the art is devoted to develop a kind of face camera that both can utilize and carries out real-time overall situation observation, can utilize the line camera to scan the beam-splitting structure of the digital pathological section scanner of picture fast again.
The utility model content
The beam-splitting structure of digital pathological section scanner of the present utility model utilizes polarization splitting prism that incident light is divided into two, and one uses to line camera scanning, and it is two for face camera scanning use, makes the use light source that both sides can be separate.
The beam-splitting structure of a kind of digital pathological section scanner of the present utility model, comprise light source, object lens, polarization splitting prism, face camera and the line camera be located on the support, described polarization splitting prism is provided with incident light plane, first polarization plane and second polarization plane, the light that described light source penetrates is injected the incident light plane of described polarization splitting prism by object lens, and respectively via first polarization plane of described polarization splitting prism inject described camera, second polarization plane is injected described line camera.
In a preferred embodiments of the present utility model, vertical mutually between first polarization plane of described polarization splitting prism and second polarization plane.
In another preferred embodiments of the present utility model, the top of second polarization plane of described polarization splitting prism also is provided with catoptron.
In another preferred embodiments of the present utility model, be the angle of 45 degree between described catoptron and second polarization plane.
In another preferred embodiments of the present utility model, also comprise condenser, described condenser is located between object lens and the polarization splitting prism.
The beam-splitting structure of digital pathological section scanner of the present utility model utilizes polarization splitting prism that incident light is divided into two, and one uses to line camera scanning, and it is two for face camera scanning use, makes the use light source that both sides can be separate.Operating personnel can select to use different camera modes according to different actual demands, both can utilize the face camera to carry out real-time overall situation observation, can utilize the line camera to scan picture fast again, have opened up the range of application of digital scanner.
