Description
Technical field
The utility model belongs to ray machine electricity one and changes apparatus field, is specifically related to a kind of helioscope guiding telescope take wedge as dioptric element.
Background technology
﹠lt, b TranNum="60" ﹠gt, ﹠lt, / b ﹠gt, helioscope is a kind of astronomical telescope that is exclusively used in the observation sun, when long-time observation, due to optics, machinery, the factors such as electrical equipment and meteorology, the picture that can make the sun slowly departs from initial position, in order to address this problem, generally adopt and install separately a less guiding lens barrel additional on the illuminating apparatus frame of looking in the distance, utilize the sun picture in guiding telescope, come artificial guiding or computing machine automatic guiding, namely artificial or computing machine is identified the deviation of guiding sun picture, control electric motor micro-motion, eliminate this deviation, the guiding picture keeps motionless, because the guiding lens barrel is fixedly mounted on body tube, and length and weight distortion are less, therefore the sun picture of primary mirror is also motionless, reached the stable target of sun picture.
To the auto-guide of the sun, four kinds of methods are arranged at present.
1, photoelectric tube auto-guide: very unstable, very responsive to the brightness of the sun, cloud amount, daylight etc., and also precision is very low, therefore substantially be eliminated;
2, line array CCD or bar shaped CCD auto-guide: the sun information of reception very little, precision is low, antijamming capability is low;
3, adopt large target surface area array CCD, to the whole imaging of the sun, the auto-guide precision is high, but large CCD is with high costs;
4, splicing is as the guiding method, and the method with cutting apart the guiding telescope object lens looks like to be divided into four to the guiding sun, and joining image-forming after deviation.For example Chinese invention patent 2,007 1 0020041.7: a kind of astronomical telescope video CCD automatic guiding method, and step is as follows: on guiding lens barrel or body tube, video CCD is installed; Process by ccd image, obtain the image of celestial body; The rotation CCD, make the movement of day body image parallel with right ascension or declination at directions X, with video CCD to the celestial body imaging; Computing machine obtains video image with capure card, carries out guiding according to this video image and variation thereof; After computing machine obtains video image by capure card, carry out the treatment scheme of guiding.Circulation is carried out said process until guiding finishes.CCD aims at middle section, has comprised the amount of exercise of sun four direction in the image of collection, and the side-play amount of Computer Analysis image can realize realizing high-resolution sun leading with little target surface area array CCD, but object lens is cut apart and the assembling more complicated of deviation.
Summary of the invention
Above-mentioned deficiency for prior art, the utility model proposes a kind of novel helioscope guiding telescope, the utility model can overcome that the prior art precision is low, antijamming capability is low, or with high costs, or object lens are cut apart and the assembling more complicated of deviation, etc. deficiency, utilize the refractive power of wedge to make sun kine bias folding, exempted and cut apart minute surface, assembling and debugging are very convenient.Simultaneously, the utility model is simple in structure, makes and assembles easily, is convenient to batch production.
The technical scheme of completing the foregoing invention task is that a kind of helioscope guiding telescope take wedge as dioptric element is equipped with video CCD on guiding lens barrel or body tube, it is characterized in that, in described leading object lens front, four wedges are installed, the angle of wedge of these four wedges is identical with shape; The installation site of these four wedges is: around the axis of leading object lens, become 90o evenly to distribute; The direction each other of these four wedges is: each becomes 90o to arrange.
Its ultimate principle still adopts splicing as the guiding method, but no longer cuts apart the guiding telescope object lens, but the wedge of four different directions is set at object lens, utilizes the refractive power of wedge to make sun kine bias folding, has exempted and has cut apart minute surface, and assembling and debugging are very convenient.
The principle of work of the helioscope guiding lens barrel take wedge as dioptric element of the utility model task, as Fig. 1, Fig. 2, shown in Figure 3:
1, Fig. 1 is the wedge schematic diagram, and wedge is transparent glass flake, and an end is thick, and an end is thin.In figure, incident ray 1, emergent ray 2.α is the wedge angle of wedge, and β is the light deflection angle, and n is glass refraction, β=(n-1). α.
2, Fig. 2, in leading object lens 3 fronts, four wedges 4,5,6,7 are installed, after the glass material of selected wedge, its refractive index n is namely definite, and the angle of wedge of four wedges is identical with shape, the convenient making and installation, but the angle of wedge respectively up and down, left and right (in figure) four direction installs, and can make the picture of the sun respectively to four position deviations, forms splicing sun picture as shown in Figure 3;
3, in Fig. 3, sun pictures that when not adding wedge, the leading object lens form with 8 of dotted line, 9,10,11,12 be respectively wedge 6,5,4,7 sun pictures that form, rectangle frame 13 is target surfaces of leading CCD camera, its central dark space 14 is the target picture of leading, has wherein carried the mobile message of sun picture at left and right and up and down both direction;
4, calculate the center of gravity of image in CCD with computing machine program timing (generally calculating once second every 5-10), utilize the side-play amount of center of gravity, control telescope and eliminate the movement of sun picture, can keep sun picture to remain on for a long time in minimum deviation, reach the target of auto-guide.
In prioritization scheme of the present utility model, the parameter of described four wedges, the following data of recommend adoption: the wedge locking angle is 32 jiaos minutes-40 jiaos minutes, and the light deflection angle beta is 16 jiaos minutes-20 jiaos minutes, and glass refraction n is 1.4-1.6.
