Abstract

PROBLEM TO BE SOLVED: To eliminate one-sided blurring even when image blurring correction amount is large and to easily prevent image blurring with a small driving force by moving a part of the erect optical system of a telescope so that the image surface position of the telescope may not be moved in a direction along an optical axis. SOLUTION: In this telescope, an object image formed by an objective lens system L1 is reflected to be erected by four reflection surfaces, and the erect object image is enlarged and observed through an ocular lens system L2. In such a case, by moving 1st and 2nd mirror units M1 and M2 in parallel, the image formed by the lens system L1 is moved right and left and up and down from an initial position in a direction orthogonally crossed with the optical axis O2 (main light beam) of the lens system L2. Therefore, by adjusting right- and-left and up-and-down moving speed, the object image is moved in any direction at desired acceleration and desired speed, so that the image blurring is prevented. Since the image surface is moved in the direction orthogonally crossed with the optical axis O2 and the distance on the optical axis is not changed, out-of-focus is prevented.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is a plan view showing an optical system of an embodiment in which the present invention is applied to a telescope, and FIG. 2 is a side view of the optical system.
Hereinafter, the horizontal direction and the vertical direction in the present specification refer to the direction in which the telescope is placed so that the optical axis of its objective lens is horizontal in consideration of the normal use state of the telescope. The direction of is called backward.

In this telescope, an object image formed by the objective lens system L1 is erected by reflection by four reflecting surfaces,
An upright object image is magnified and observed by an eyepiece lens system L2, and the objective lens system L1, the first reflecting surface 11, the second reflecting surface 12, the third reflecting surface 13, and the fourth are arranged in order from the object side on the optical path.
The reflecting surface 14 and the eyepiece lens system L2 are provided. The first and second reflecting surfaces 11 and 12 are integrally formed as a first mirror unit M1 and are orthogonal to each other, and the third and fourth reflecting surfaces 13 and 14 are integrally formed as a second mirror unit M2 and are orthogonal to each other. doing. Also, the first and third reflecting surfaces 1
1, 13 constitute the front reflecting surface, and the second and fourth reflecting surfaces 12,
14 forms a back reflection surface.

A light beam incident from the objective lens system L1 (a principal ray incident along the optical axis O) is reflected by the first reflecting surface 11 in the horizontal direction orthogonal to the optical axis O, and by the second reflecting surface 12. The light is reflected forward (in the object direction) in parallel with the optical axis O, vertically downward in the third reflective surface 13 orthogonal to the optical axis O, and in the fourth reflective surface 14 backward (in the observer direction) in parallel with the optical axis O. ) Is reflected. The first, second, third, and fourth reflecting surfaces 1 described above
By the reflection of 1, 12, 13, and 14, the objective lens system L
The object image (aerial image) formed by 1 is erected.
The observer magnifies and observes this erect object image through the eyepiece lens system L2.

Image blur prevention (image blur correction) of the present embodiment
The principle of is further described with reference to FIG. FIG. 3 shows the field of view of the observer. In FIG. 1, the first mirror unit M1 is arranged in a direction parallel to a direction that bisects an angle formed by a chief ray incident on the first reflecting surface 11 and a chief ray reflected by the second reflecting surface 12, that is, , In the direction H (horizontal left) parallel to the surface orthogonal to the optical axis O and orthogonal to the first reflection surface 11 and the second reflection surface 12, to the position indicated by the broken line. Then, the optical path of the light beam incident on the eyepiece lens system L2 moves in parallel by ΔH to the position shown by the broken line. In the field of view of the observer, the object image 21 translates leftward to the position indicated by the broken line (object image 21 ') (see FIG. 3 (A)).
Conversely, if the first mirror unit M1 is moved to the right,
The object image 21 moves in parallel to the right (see the object image 21 ″ in FIG. 3A). Note that FIG. 4A and FIG.
In the embodiment shown in, the chief ray (1) incident on the first reflecting surface 11 and the chief ray (2) reflected by the second reflecting surface 12
The figure explaining the direction which bisects the angle (alpha) which is formed is shown.

In FIG. 2, in the second mirror unit M2, the direction in which the principal ray reflected by the second reflecting surface 12 is incident on the third reflecting surface 13 and the direction by which it is reflected by the fourth reflecting surface are equal to each other. Move to the position indicated by the broken line in the direction parallel to the dividing direction, that is, in the direction V (vertical downward) parallel to the plane orthogonal to the optical axis O and orthogonal to the third reflection surface 13 and the fourth reflection surface 14. Then, the optical path of the principal ray incident on the eyepiece lens system L2 moves downward by ΔV as shown by the broken line. That is, the position where the object image 21 is shown by the broken line (object image 21 ')
Up to the direction perpendicular to the chief ray (Fig. 3
(B)). On the contrary, when the second mirror unit M2 is moved upward, the object image 21 is moved upward in parallel (FIG. 3).
See (B) object image 21 ″).

As described above, the first and second mirror units M
By moving 1 and M2 in parallel, the objective lens system L1
Is formed by the optical axis O2 of the eyepiece lens system L2.
Since it moves left and right and up and down from the initial position in the direction orthogonal to the (main ray), the object image can be moved at any desired acceleration and speed in any direction by adjusting the left, right, up, and down movement speeds to reduce the image blur. It can be prevented. Moreover, since the image plane moves in the direction orthogonal to the optical axis O2 and the distance on the optical axis does not change, no focus shift occurs.

In the above description, in order to make the principle of image stabilization (image blur correction) of the present invention easy to understand, the image is moved while the telescope is stationary, but in reality, when the telescope vibrates or shakes. In this case, the object image 21 observed by the observer does not vibrate or shake within the field of view, or the field of view does not vibrate or shake. Therefore, horizontal and vertical vibrations and shakes of the telescope are detected by an angular velocity (angular acceleration) sensor, and the first and second mirror units M1 and M1 are detected based on the detected values.
The image blur is prevented by driving M2 at a predetermined speed in a direction in which the movement of the image observed by the observer is canceled.

In this embodiment, the vibration and camera shake of the telescope are detected by the horizontal angular velocity sensor 43 and the vertical angular velocity sensor 45 as the horizontal and vertical angular velocities of the optical axis O. When the telescope (optical axis O) shakes, the angular velocity sensors 43 and 45 detect it and output a detection signal to the control circuit 41. Normally, the control circuit 41, which is composed of a microcomputer, calculates the driving directions and the driving speeds of the horizontal and vertical drive actuators 31 and 33 based on the input detection signal. Then, the control circuit 41 controls the horizontal drive circuit 4

Due to the movement of M21, the image plane moves in the blurring direction of the optical axis O2 of the eyepiece lens system L2 viewed from the observer to prevent movement of the observer's field of view, that is, vibration and blurring of the field of view.

As described above, according to the present embodiment, the image blur is corrected (prevented) by shifting the object image formed by the objective lens system in the direction perpendicular to the optical axis of the eyepiece lens system. Even if it is large, the image will not be blurred.
