Abstract
The utility model relates to a rotary scanning telescope, which has a light transmission lens or a reflecting lens face, a rotating mechanism and an imaging recorder. The light transmission lens is a cutting slice passing through the central line on a rotating convex lens and having two cutting faces symmetric to the central line; the cutting slice can be equal to a flat glass bar that wears the two cutting faces into curved surfaces of lens; the reflecting lens face is worn with a parabolic mirror curved surface on one side face and long strip glass or ceramic plated with light reflecting film. The rotating mechanism comprises a fixed lens or the motor rotor or stator of the reflecting lens face; the focus behind the ocular is provided with a CCD imager. The utility model adopts rotating scanning imaging and changes the hulking rotating light transmission convex lens into thin strip shape slice, thereby greatly reducing the production cost, guaranteeing the precision of the curved surface and improve the imaging quality so as to make the production of large scale and ultra-large scale astronomical telescope be possible.
Description
The utility model is a kind of rotation sweep telescope of observing the remote object of space or ground.
Existing astronomical telescope or conventional telescope are to make primary mirror, i.e. object lens with the glass lens of monoblock or the mirror surface of monoblock.Because the size of general astronomical telescope is big, diameter surpasses 2 meters, and weight all surpasses one ton, and so huge size and weight makes that not only its manufacturing is very difficult, also makes its installation and control also become very complicated, and manufacturing cost is high.In addition, because the weight of lens or mirror surface self is too big, the deadweight distortion takes place very easily during work, image quality is reduced greatly.Make large-scale ultra-large type astronomical telescope especially prior art also be difficult to the problem that overcomes.
The purpose of this utility model is to propose a kind ofly can to reduce manufacturing cost greatly, to reduce weight and manufacture difficulty, can significantly improve the equivalent lens diameter again, thereby can observe the rotation sweep telescope of more remote celestial body, to overcome the deficiencies in the prior art.
This rotation sweep telescope that the utility model proposed, it has transmission lens or mirror surface, rotating mechanism and record by imaging device, it is characterized in that described transmission lens is a section on the rotation convex lens, and mirror surface is a section of rotation concave mirror.
Transmission lens was the section that center line and two tangent planes are symmetrical in center line, and this section can be equal to the sheet glass bar of two cut sides being worn into lens curved surface.
Transmission lens or mirror surface are in-line eyeglass, star eyeglass or cruciform eyeglass.
Transmission lens can be uniform thickness also can be the fan-shaped section of uniform thickness not.
Mirror surface is to grind into the parabolic lens curved surface on the side, and is coated with the rectangular glass or the pottery of reflective membrane on the curved surface.
Mirror surface can be to wait width, also can be the fan-shaped section that does not wait width.
Rotating mechanism has the motor rotor of fixing len or mirror surface and promotes the stator of rotor rotation, and the focus place of eyepiece back is mounted with imager.
Transmission lens or mirror surface that rotor drives, its rotation mode are 180 degree, 90 degree or continuous arbitrarily angled rotations.
Imager is chemical sensitive film, perhaps CCD electrofax machine.
The utility model adopts the mode of rotating scan imaging, the rotation printing opacity convex lens or the rotary reflection concave mirror of heaviness have been become thin bar shaped section, greatly reduce telescopical manufacturing cost, because the minimizing significantly of curved surface, guaranteed the machining precision of curved surface from technology, improved image quality, manufacturing is large-scale, the aperture becomes possibility greater than 50 meters ultra-large type astronomical telescope thereby make.
Further specify the utility model with accompanying drawing and example below.

In Fig. 1-10:
1-transmission lens or mirror surface; 2-lens barrel or large-scale framework; The 3-motor rotor; The 4-motor stator; 5-has the telescope lens barrel now; Existing telescopical rotary reflection concave mirror of 6-or rotation printing opacity convex lens; The 7-imager; 8-has telescopical eyepiece now.
Embodiment one
Transmission lens is long with 5 meters, the sheet glass bar of 5 millimeters thick grinds and forms, and its two ends are fixed on step motor and pass on the son, and the step motor stator is fixed on the large-scale lens barrel, and the angle of rotation of step motor is per step 0.01 degree.Eyepiece uses the eyepiece of conventional telescope, and imager electronic CCD camera allows it finish image recording.After step motor rotated for 36000 steps, a width of cloth space image just was recorded in the electrofax machine.Because its object lens are equivalent to the rotation printing opacity convex lens of the astronomical telescope of 5 meters of diameters, its sharpness is equal to it.Weight and cost then only reach a thirtieth of existing same specification astronomical telescope.
Embodiment two
Mirror surface is long with 10 meters, the sheet glass of 10 millimeters thick grinds and forms, and plates the layer of aluminum reflective membrane on the face of grinding, and its two ends are fixed on the rotor of step motor, utilize reflective surface to collect light.The employing d.c. motor drives, and light arrives imager by eyepiece after reflection, and imager is the sensitive film that ordinary camera is used, and after motor rotates a circle, just stays the space image on the film.Because its reflecting surface is equivalent to the object lens of the large-scale reflection astronomical telescope of 10 meters of diameters, the effect of being watched is equal to the autocollimator of this same specification, yet weight and cost have only its 1/40th.
