The utility model relates to a newton rings image acquisition device links together reading microscope with the camera is effectual for can estimate under the same environment and gather the image, clear, indeformable newton rings can be shot through the rotation plane mirror to accurate two kinds of methods of measuring plano -convex lens curvature radius of comparison, more accurate measurement plano -convex lens's curvature radius.
Description
Technical field
The utility model belongs to Application Optics equipment technical field, is specifically related to a kind of Newton's ring IMAQDevice.
Background technology
General Newton's ring is measured and is applied the mode that all adopts artificial reading, easily causes operator's eyesight tiredLabor, produces larger error in reading, affects measurement result. The precision of measuring for improving Newton's ring, can adoptDigital image processing techniques are measured accurately to the radius of curvature of Newton's ring.
Existing a lot of image collecting device, as machine vision instrument, scanner, digital camera etc., noBut cost is high and complex structure, and cannot reasonably be arranged on reading microscope and can be to the knot of measuringFruit is caused larger error.
Utility model content
The purpose of this utility model is to provide a kind of Newton's ring image collecting device, has solved in prior artNot problem accurately of measurement result when the Newton's ring existing is measured.
The technical scheme that the utility model adopts is that a kind of Newton's ring image collecting device, comprises " L "Type support, the length of support has circular the first through hole and square three-way groove in plane, and the first through hole is embedded withReading microscope, groove is embedded with camera, has circular the second through hole in the short plane of support, theIn two through holes, be provided with level crossing.
Feature of the present utility model is also,
The equal diameters of the internal diameter of the lens barrel of reading microscope and the first through hole, the object lens of reading microscope are wornCross the first through hole, the length that the short plane of the object lens of reading microscope and support is positioned at support is same to planeSide.
The base of camera is connected with support by nut, and the object lens of camera and reading microscope are positioned at and prop upThe length of frame is to the homonymy of plane.
Level crossing be positioned at camera under.
Camera is connected with computer by video line.
The beneficial effects of the utility model are: a kind of Newton's ring image based on image processing of the utility modelHarvester is simple in structure, easy to use, be convenient to remove and install. Owing to having connected reading microscope and having taken the photographPicture head, can successively obtain image that same Newton's ring instrument observes by reading microscope and by shootingThe image that head collects compares, and not affected by environment, temperature etc., more accurately relatively two kinds of measurementsThe quality of method.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
A kind of Newton's ring image collecting device of the utility model, structure as shown in Figure 1, comprises that " L " type props upFrame 1, as shown in Figure 2, the length of support 1 has circular the first through hole 2 Hes to support 1 structure in planeSquare three-way groove 3, the first through holes 2 are embedded with reading microscope 7, the internal diameter of the lens barrel of reading microscope 7With the equal diameters of the first through hole 2, the object lens of reading microscope 7 are through the first through hole 2, and reading is micro-The short plane of the object lens of mirror 7 and support 1 is positioned at the length of support 1 to the homonymy of plane, and groove 3 is embeddedHave camera 5, the base of camera 5 is connected with support 1 by nut, and camera 5 passes through video line8 are connected with computer, the image collecting can be sent to computer, camera 5 and reading microscope 7Object lens be positioned at the length of support 1 to the homonymy of plane, in the short plane of support 1, have circular second logicalIn 4, the second through holes 4 of hole, be provided with level crossing 6, can make incident light through anti-by rotational plane mirror 6Penetrate rear vertical irradiation to Newton's ring.
When reading microscope 7 is installed, the object lens of reading microscope 7 are taken off, then reading microscope7 lens barrel passes the first through hole 2, and then object lens are arranged on lens barrel.
Groove 3 has through hole around, camera 5 embed groove 3 interior after, connect and will take the photograph by nutThe base of picture 5 is fixed with support 1.
In the utility model, camera 5 is positioned at same level with the object lens of reading microscope 7.
When use, below a kind of Newton's ring image collecting device of the utility model, place Newton's ring instrument, logicalCross the microdrum that rotates reading microscope 7, make Newton's ring instrument first be placed on reading microscope 7 and shootingUnder 5, so that obtain the data of same Newton's ring instrument by range estimation and the method priority that gathers image,To reach the effect of these two kinds of measuring methods of comparison.
A kind of Newton's ring image collecting device of the utility model is simple in structure, easy to use, be convenient to dismounting peaceDress; Having made up conventional images harvester cannot show at reading by reasonable installation by the restriction of frame for movement simultaneouslyDefect on micro mirror.
A kind of Newton's ring image collecting device of the utility model is effective to reading microscope 7 and camera 5Link together, make under equivalent environment, to realize artificial visually examine and measure and gather two kinds of image measurementsMeasuring method, and the quality of two kinds of measuring methods relatively accurately, can take by rotating mirror 6To clear, indeformable Newton's ring, measure more accurately the radius of curvature of planoconvex spotlight.
