Abstract
The present invention relates to a method and a device for the photoelectric image conversion of an optical microscope. In the method, optical images are directly converted into electrical image signals by the coincidence of the photosensitive surface of a CMOS (Complementary Metal Oxide Semiconductor) imaging sensor and the image surface of an objective lens of the optical microscope. The device for realizing the method comprises a cylindric casing body with a positioning lug boss; an infrared cut-off filter, the CMOS imaging sensor and a CMOS driver circuit board are orderly arranged in the casing body from bottom to top. When in use, only the device needs to be inserted into the eye lens cylinder of the optical microscope. The present invention has the advantages of simple structure and low cost; the present invention can realize the photoelectric image conversion with high quality without any relay optical system.
Description
Technical field
The present invention relates to a kind of conversion equipment of optical microscope photoelectric image.
Background technology
People become can be monitored the electricity picture signal of device or computer Recognition by the Optics in Microscope image transitions of photoelectric image conversion with visualization, so that the Optics in Microscope image is carried out screen display or processing, analysis and storage.Obviously, the application function of optical microscope has been widened in the application of photoelectric image switch technology effectively, is widely used in fields such as teaching, medical science and fine detection, analysis, demonstration.For a long time, the photoelectric image conversion for optical microscope rests on the employing charge-coupled device (CCD) always.Because the driving circuit of CCD is quite complicated, bulky, all need adopt relay optical system that optical imagery is transformed into the CCD photosurface when therefore being used for microscope, could realize the opto-electronic conversion of image, not only picture element difference and cost height, big, the use inconvenience of structure.
Summary of the invention
The objective of the invention is to propose the directly method of conversion of a kind of optical microscope photoelectric image that can obtain to have good picture element, simultaneously for adopting this method to design the photoelectric image conversion equipment of a kind of low cost, light structure, optical microscope easy to use.
In recent years, developed a kind of on chip piece imaging sensor---complementary type oxide semiconductor (the being abbreviated as CMOS) imaging sensor of integrated light-sensitive array device and treatment circuit.
The direct transformation approach of optical microscope photoelectric image that the present invention proposes is the cmos imaging sensor of placing cutoff filter and drive circuit board is housed in optical microphotograph eye-lens of the eyepiece tube, and the photosurface of cmos imaging sensor is overlapped with the imaging surface of micro objective, the optical imagery after directly will filtering through IR-cut converts the electricity picture signal to.
For realizing that the photoelectric image conversion equipment that said method designs comprises the housing with positioning boss that is used to insert optical microscope eye lens tube, cutoff filter, cmos imaging sensor and CMOS drive circuit board are installed in housing from bottom to top successively, wherein the photosurface of cmos imaging sensor is positioned on the imaging surface of micro objective, and the power lead and the image signal line of CMOS driving circuit stretch out housing.During use, the photoelectric image conversion equipment is inserted in the tube of optical microscope eye lens tube, then the optical imagery of micro objective can be directly changed into the electricity picture signal through the cmos imaging sensor again and be passed to display screen or computing machine through cutoff filter.
Because being the photosurface with the cmos imaging sensor, the present invention overlaps with the micro objective imaging surface, therefore needn't can directly convert the optical imagery high-quality to the electricity picture signal by any relay optical system, again because the light-sensitive array device and the treatment circuit of cmos imaging sensor are to be integrated in in the chip piece, its volume is little, price is low, so the photoelectric image conversion equipment that adopts the cmos imaging sensor to make has the characteristics of low cost, light structure, brings convenience to use.
Description of drawings
Fig. 1 is a kind of concrete structure synoptic diagram of the present invention;
Fig. 2 is a kind of application example of the present invention.
Embodiment
The photoelectric image conversion equipment that is used for optical microscope shown in Figure 1, comprise cylindrical shell 1 with positioning boss 2, cutoff filter 4, cmos imaging sensor 5 and CMOS drive circuit board 7 are installed in cylindrical shell from bottom to top successively, and the power lead 3 and the image signal line 6 of CMOS driving circuit stretch out housing.Can cooperate closely with the eye lens tube for this device is inserted in the microscope eye lens tube, guarantee image stabilization, example is set O shape rubber ring 9 on the cylindrical wall below the housing positioning boss 2 as shown.Because the imaging surface of microscopical object lens 12 generally is in 10mm place (see figure 2) in eye lens tube 11 end faces, therefore making the photosurface 8 of cmos imaging sensor and the distance between the positioning boss 2 usually is 10mm, like this, this device is inserted microscope eye lens tube, utilize positioning boss 2 near eye lens tube end face location, microscopical object lens imaging surface is overlapped with the photosurface of cmos imaging sensor.
