Description
Technical field
The utility model relates to the amplification microscopic photography field in photoelectric detecting technology, especially relates to a kind of amplification micro image shooting device.
Background technology
In the end of the century in Christian era 16, the letter proper Li Yasi Jansen father and son of Holland has invented the first in the world platform microscope.Since then, the mankind start to carry out minute observation to microcosmos.The recording means of micro-imaging experienced by Freehandhand-drawing, film, until digital sensor of today.The utilization of digital sensor, directly can show shooting results after shooting completes, and significantly improves efficiency and the effect of photologging, significantly reduces shooting cost and technique for taking threshold simultaneously.
Amplification, microlens are limited to optical technology and material, often cannot take into account the depth of field and numerical aperture.The depth of field is that optical observation system in the direction of the optical axis can the scope of blur-free imaging, and the depth of field is larger, and the depth bounds can observed in the direction of the optical axis is wider.Numerical aperture is the important technological parameters of micro objective, and characterize the height of resolution of lens, numerical aperture is larger, and resolution is higher, but the depth of field is less.Therefore, how to ensure that high-resolution and the large depth of field are the active demands of current microscopic filming system simultaneously.
Under the high-resolution prerequisite of guarantee camera lens, synthetic technology is stacked by focus, by taking a series of continuous focusing in the image of subject different depth, using focus to stack software and this series of images being synthesized the image of a width in all shape library of each degree of depth.
The depth of field is less to be caused when carrying out amplification micro-image, and the fine setting of the focusing degree of depth seems very important, and electromotion focusing device is used in more and more to be amplified in microscopic system.The introducing of electromotion focusing device, also making automatic ranging change the focusing degree of depth becomes possibility.
Meanwhile, specialty amplifies the special ccd sensor of the many uses of micro image shooting system at present, and its image taking performance is generally poor, particularly in pixel and ISO imaging.Market today single-lens reflex plate optical finder digital camera or miniature single-lens digital camera more outstanding than the special ccd sensor of microscopic system far away in these two aspects, the highest valid pixel has reached 3,640 ten thousand, top high photographic sensitivity 409600, and relative low price.
And specialty amplifies the mode of micro image shooting system many employings imaging system and articles holding table integration at present, though enhance the integrality of system, but also cause the vibrations of digital imaging component and focusing component to be directly delivered to subject, captured a series of continuous focusings subject in the image of different depth is easily caused to be subjected to displacement, finally affect synthetic effect, even cause synthesizing unsuccessfully.
Photoflash lamp, as the introducing of photographic light sources, also significantly improves the intensity of photographic light sources, the shooting time for exposure is significantly shortened, reduces the shake caused because the time for exposure is longer fuzzy.
Summary of the invention
The purpose of this utility model is to provide the resolution not reducing and amplify microscopic filming system, take into account system cost and versatility, improve while amplifying micro-image pixel, increase automatic control function, the one possessing the super depth image ability of shooting synthesis amplifies micro image shooting device.
The utility model is provided with stepping motor, stepping The Cloud Terrace, Quick-mounting board, draws and dodge device, camera, controller, switching cylinder, photography bellows, camera lens, photoflash lamp and articles holding table;
Stepping motor is located on stepping The Cloud Terrace, stepping The Cloud Terrace is fixed on tripod, connect camera, switching cylinder, photography bellows and camera lens from top to bottom successively, camera is connected with stepping The Cloud Terrace by Quick-mounting board, drawing sudden strain of a muscle device is arranged on camera, and guarantee that the optical axis of camera lens is vertical, controller is connected with stepping motor by power line, controller is connected with camera by cable release, realizes the control articles holding table of controller to stepping motor and camera; Articles holding table is located at the below of camera lens, and the top of articles holding table is located at by photoflash lamp, and subject is placed on articles holding table.
The utility model is according to the camera lens used, select suitable adapter ring connection lens and photography bellows, photography bellows and camera use adapter ring to be connected, bellows spacing is regulated to make lens imaging in camera photo-sensitive cell, adjustment wireless flash lamp, control step The Cloud Terrace is observed camera optics view finder or liquid crystal screen of finding a view and is focused, and can control camera and take after confirming shooting focus.
When the shooting of super depth image need be carried out, only need set initial shooting focusing position, stop focusing position and always take quantity by controller, namely carry out the image of a series of continuous focusing change by controller automatic control step The Cloud Terrace and camera.Picture is imported computer, and utilize focus to stack high-resolution that software process quality one width contains each deep image information of subject surpasses the depth of field and amplifies micro-image.Here it should be noted that, between shooting image-forming assembly of the present utility model (containing camera, camera lens, stepping The Cloud Terrace etc.) and articles holding table without physical connection, use Wireless remote-controlled flashing lamp, and when taking adopt the modes such as The Cloud Terrace moves rear dwell interval, slr camera reflector rises in advance reduce thrashing.
The utility model do not reduce amplification, microscopic filming system resolution basis on, take into account system cost and versatility, improve and amplify micro-image pixel, possess abilities of single width shooting and several automatic shootings continuously simultaneously.
