Abstract
The utility model relates to an ultrahigh pixel digital image optical imaging instrument which comprises an optical system assembly, an optical system imaging surface, an auxiliary coefficient lens, a CCD collecting instrument, a digital circuit processing device, a computer, a display, a printing device, etc. The utility model is characterized in that the auxiliary coefficient lens is an auxiliary correction lens which can further amplify the imaging surface of an optical system, and the CCD collecting instrument is a dynamic scanning CCD collecting instrument which is matched with a step motor of which each step is less than 1 mum. The dynamic scanning CCD collecting instrument greatly enhances the image resolution, and the definition can reach the effect of a photosensitive picture in a darkroom. The utility model solves the technical problems of the discrepancy between image multiplying power and image taking area, the discrepancy between image definition and amplification ratio, etc. which exist for a long time.
Description
Technical field
The utility model relates to optical instrument, particularly a kind of very-high solution digital picture optical imagery instrument.
Background technology
Optical instrument comprises all kinds of microscopes, telescope, X-ray machine, spectrometer and electron microscope etc.With MIcrosope image digital signal acquiring instrument is example, all is so far to adopt fixing static CCD target surface.Size from 1/4 inch to 1 inch between, effectively light-sensitive surface 2 * 2 is to 20 * 30mm, the valid pixel value is 180,000 to 8,000,000, best result distinguishes that ability is more than the 3 μ m.Because its auxiliary correction is thrown to the CCD target surface after camera lens artificially compresses the microscopic system imaging surface, must reduce the due resolution of micro-image like this, and the capture area is little, can produce new image aberration again, as spherical aberration, aberration, filed curvature etc., (under 90 * 120mm) requirements, the own multiple of image multiple and microscope produces difference at the standard breadth.Because CCD is static the collection, and its maximum resolution characteristic is subjected to the restriction of target surface fixed measure, pixel value can only reach 8,000,000 pixels (about 3000 * 2700) at present at most in addition.The image effective resolution is then lower, at most only reaches 600dpi.
Summary of the invention
The purpose of this utility model is the above-mentioned difficulties that will overcome on the prior art, and a kind of very-high solution digital picture optical imagery instrument is provided, and image resolution ratio is significantly improved, and sharpness reaches the effect of darkroom sensitization photo.
Solution of the present utility model is: this imager comprises module of optical system, optical system imaging face, auxiliary coefficient camera lens, CCD Acquisition Instrument successively, digital circuit treating apparatus, USB output interface, computing machine and display and printing equipment etc. is characterized in that said auxiliary coefficient camera lens is the auxiliary correction camera lens that the optical system imaging face is further amplified; Said CCD Acquisition Instrument is a dynamic scan CCD Acquisition Instrument.
Above-mentioned dynamic scan CCD Acquisition Instrument is provided with the stepper motor of every stepping 0.6-2 μ m.
The utility model compared with prior art has following advantage:
1. many optical instruments such as microscopical imaging surface further can be amplified, significantly improved the resolution of optical imagery, not only can avoid new aberration to occur, and guaranteed that image multiplying power and microscope should have multiplying power consistent, the capture area significantly improved, solved a series of guardian technique problems such as contradiction between contradiction, image definition and the magnification between the image multiplying power and capture area for a long time.
2.CCD the dynamic acquisition mode is step-scan, every stepping can be less than 1 μ m, but and high speed acquisition, effectively light-sensitive surface can reach 40 * 290mm, so need not system diagram is looked like to dwindle, valid pixel is broken through ten million high point easily, and can reach the desired resolution of user by regulating motor stepping sweep parameter.The highest picture pixel of image can reach more than 900,000,000 (32760 * 32760dpi), can reach more than 3,600,000,000 (6500 * 6500dpi) by maximum after the Computer Processing.Sharpness reaches the image definition of having only the darkroom photo just can obtain fully.Efficient is tens times of darkroom photo, complete alternative heavy dark room operation, and avoid the pollution that suffers in the Darkroom Disposal Process.Solved that people thirst for solving for a long time but the technical barrier of not succeeding all the time.
3, the consumptive material and the cost of taking pictures have been reduced.
Description of drawings
Fig. 1 is a very-high solution digital picture microscope optical system structural representation.
Embodiment
Referring to accompanying drawing, light path system and dynamic scan CCD are the cores of this device.The light transmission microscope optical system assembly 2 that observing object 1 sends is dispersed the picture of amplification through optical system imaging face 3 and 4 formation of auxiliary coefficient camera lens, projects on the dynamic scan CCD Acquisition Instrument 5 again.Dynamic scan CCD comprises charge-coupled device, probe and step motor drive etc., and effect is that the light signal with the camera lens imaging changes into electric signal.Those skilled in the art can both be made dynamic scan CCD as required, belongs to prior art.Dynamic scan CCD acquisition mode is step-scan, and every stepping can be less than 1 μ m.5 signals converted of dynamic scan CCD Acquisition Instrument are carried to computing machine 8 through digital processing circuit 6, line and USB output interface 7.The image that is input to computing machine is stored in the hard disc of computer.Print final photo by printer 10 then.Can also direct viewing on display 9.The primary optical axis of above-mentioned each eyeglass should overlap.The said optical imagery instrument of the utility model comprises all kinds of microscopes, as type microscopes such as metallographic, physics, biology, ore deposit phase, polarisation, details in a play not acted out on stage, but told through dialogues, fluorescence, Nuo Mansiji phase contrast, infrared, ultraviolets.Also comprise professional telescope, infrared telescope, X-ray machine, spectrometer, electron microscope, diffractometer and special-purpose microhardness testers etc. in addition, have wide range of applications.
