Embodiment
By reference to the accompanying drawings Telescope Teaching instrument structure of the present invention is illustrated.
Telescope Teaching instrument structure of the present invention is that this Teaching instrument comprises Telescope 1, support 2, camera head 3, power transformer 4, signal wire 5, display device 6; Described support 2 front portions are fixed on the lens barrel of Telescope 1, can be with lifting, pitching and the rotary synchronous motion of lens barrel; Camera head 3 is installed on support 2 rear portions, and camera head 3 is connected with power transformer 4, and camera head 3 is connected with display device 6 by data line 5, and the video signal transmission of camera head 3 is in display device 6.
Described camera head 3 is analog, adopts simulating signal video camera to add camera lens as camera head, usings concentric cable as data line signal transmission, adopts with the TV of video signal input terminal mouth or display as display device; Described camera head 3 is digital, adopts USB interface digital camera as camera head, adopts USB line as data line signal transmission, adopts computing machine to receive signal, by computer screen, shows image.The camera lens visual angle of described camera head 3 is at 25 to 50 degree, all over the screen or approach clear demonstration all over the screen in display device 6 to guarantee visual field in telescope 1.
Described support 2 is fixed on by jackscrew on the lens barrel of telescope 1, after support 2 is fixing by the lens barrel of telescope 1 and camera head 3, and the lens barrel synchronizing moving of support 2, camera head 3 and telescope 1.By the horizontal beam on described support 2 and the vertical adjustable camera head of post 3 all arounds and moving up and down, be fixed on the position needing.There is opening the lens barrel upper end that described support 2 is fixed on Telescope 1, the foresight that the lens barrel rear end that makes camera head 3 can observe Telescope 1 when upper position is aimed at.By described support 2, the position of camera head 3 relative telescopes 1 is regulated and fixed on three-dimensional: the point over against the eyepiece of telescope 1 and centered by just during contact by the camera lens of camera head 3, front and back be not less than ± 2cm of range of adjustment, to adapt to angle lens and the focal length of telescope 1; Be not less than ± 10cm of left and right adjusting scope, takes for the both sides at telescope 1; Upwards range of adjustment is not less than 5cm, for take aiming process by foresight; Range of adjustment is not less than 1cm downwards, for finely tuning camera head; Described camera head 3 is fixed on arbitrarily angled around the vertical post of support 2, the luffing angle of camera head 3 all can be-90---between+an angle of 90 degrees, regulate.
