Embodiment Construction

[0041] In order to better illustrate the image stabilization method of the present invention, first review the image stabilization principle of a conventional monocular telescope. figure 1 The shown telescope comprises a tube 5 , an objective 2 and an eyepiece 9 . The normal to the principal plane of the objective 2 defines the principal optical axis 4 on which the objective node 3 lies. All light incident through the objective node 3 does not change the direction of propagation.

[0042] The parallel light beam 1 from a distant object is converged by the objective lens 2, focused and imaged on the intermediate image plane 7, and then the light continues to advance, is collimated by the eyepiece 9, and then enters the eyeball 10 of the observer. This collimated light is imaged on the retina so that the observer sees the object magnified. In order to see the positive image, a plurality of reflective surfaces are commonly used to form a positive image mirror group to reverse t...

Abstract

The invention discloses an image-stabilizing binocular telescope, which comprises a telescope shell which is internally provided with a left eye telescoping light path and a right eye telescoping light path, and is characterized in that a left object lens and a right eye lens belong to the right eye telescoping light path, a right object lens and a left eye lens belong to the left eye telescoping light path, the right eye telescoping light path and the left eye telescoping light path are not shadowed by each other, and are in three-dimensional cross, an anascope group is respectively arranged between one object lens and one eye lens of the two telescoping light paths, and the right eye telescoping light path and the left eye telescoping light path are combined with the anascope group to form an image-stabilizing assembly shared by the two telescoping light paths, and the image-stabilizing assembly is installed in the telescoping shell through a gimbal suspension. The simple direct image-stabilizing device disclosed by the invention can accurately and synchronically eliminate the rotation of an image seen by eyes, simultaneously, can effectively restrain the nutation of a spinning sop, and can lock / unlock the image-stabilizing assembly, so that in carrying, the image-stabilizing assembly can be locked in the telescoping shell, and can flexibly rotate in observation.

Description

technical field [0001] The invention relates to an optical system with image stabilization measures. More specifically, a stabilized binocular. Background technique [0002] When observing with a handheld telescope, the user's grip cannot be as stable as a tripod. The user's body shaking, blood pulse, arm tremor, etc. will cause the telescope to vibrate slightly. If there is no image stabilization measure, the image that the user sees through the telescope will also shake. The larger the angular magnification (magnification) of the telescope, the more serious the image shake. Generally speaking, telescopes with a magnification of more than 15× are difficult to use by hand, and must be equipped with corresponding brackets. However, in cars, boats, and airplanes, the bracket that bumps with the carrier has little effect on the image stabilization of the telescope. The shake of the image will seriously damage the information content of the image, which is very unfavorable ...
