When the first reflective component 210 moves to the first position along the negative Z axis direction parallel to the chord surface 213, compared with the initial position, the first Pythagorean reflective surface 211 will reflect the incident light earlier and the second The Pythagorean reflective surface 212 will reflect the incident light later, so that when the light leaves the chord surface 213, it is offset by a distance of 2L in the negative Z-axis direction. Similarly, the first reflective member 210 can also move a distance L to the left along the positive Z-axis direction parallel to the chord surface 213 to the left Compared with the initial position, the first Pythagorean reflective surface 211 will reflect the incident light later and the second Pythagorean reflective surface 212 will reflect the incident light earlier, so that when the light leaves the chord surface 213, it moves toward the negative Z axis.

When the first reflective member 210 moves down a distance L along the negative X-axis direction perpendicular to the chord surface 213 to the first position, compared with the initial position, the first Pythagorean reflective surface 211 will reflect the incident light earlier and The second Pythagorean reflective surface 212 will reflect the incident light earlier, so that when the light leaves the chord surface 213, it will shift to the negative X-axis by a distance of 2L. This will cause the focal length to be reduced, resulting in a shortening of the focal length. , Making the focal length of the optical system shorter. Similarly, the first reflective member 210 can also move up a distance L along the positive X-axis direction perpendicular to the chord surface 213 to the second position. Compared with the initial position, the first Pythagorean reflective surface 211 will be reflected later. Light and the second Pythagorean reflective surface 212 will delay the reflection of the incident light, so that when the light leaves the chord surface 213, it shifts to the positive X-axis by a distance of 2L, which causes the focal length to increase, resulting in an elongated focal length The change effect of the optical system makes the focal length of the optical system longer. In this way, moving the first reflecting member 210 along the X axis perpendicular to the chord surface 213 can achieve the effect of adjusting the focal length.

Then, after the light is reflected by the second reflecting member 240, the light is imaged on the image sensor 230.

In the fourth embodiment of the lens device of the present invention shown in FIG. 13C, when the first reflective member 210 is at the initial position, the first Pythagorean reflective surface 211, the second Pythagorean reflective surface 212, and the chord surface 213 are all The solid line represents; when the first reflective component 210 moves a distance L to the right along the negative Z-axis direction parallel to the chord surface 213 to the first position, the first Pythagorean reflective surface 211 and the second Pythagorean reflective surface 212 And the chord surface 213 are all represented by dashed lines. When the first reflective component 210 moves to the first position along the negative Z axis direction parallel to the chord surface 213, compared with the initial position, the first Pythagorean reflective surface 211 will reflect the incident light earlier and the second The Pythagorean reflective surface 212 will reflect the incident light later. Then the light enters the second reflecting part 240 and is reflected to the image sensor 230 by the second chord surface 243 of the second reflecting part 240. After the light leaves the second reflecting member 240, it is offset by a distance of 2L in the negative X-axis direction. Similarly, the first reflecting member 210 can also move a distance L to the left along the positive Z axis direction parallel to the chord surface 213 to the second position. Compared with the initial position, the first Pythagorean reflecting surface 211 will delay reflection. The incident light and the second Pythagorean reflection surface 212 will reflect the incident light earlier. Then the light enters the second reflecting part 240 and is reflected to the image sensor 230 by the second chord surface 243 of the second reflecting part 240. After the light leaves the second reflecting member 240, it is offset by a distance of 2L in the positive X-axis direction.

When the first reflective member 210 moves upward by a distance L along the positive X-axis direction perpendicular to the chord surface 213 to the first position, compared with the initial position, the first Pythagorean reflective surface 211 will later reflect the incident light and The second Pythagorean reflective surface 212 will reflect the incident light later. Then the light enters the second reflecting part 240 and is reflected to the image sensor 230 by the second chord surface 243 of the second reflecting part 240. After the light leaves the second reflecting part 240, it is offset by a distance of 2L in the positive X-axis direction. As a result, the focal length is increased and the focal length is elongated, so that the focal length of the optical system becomes longer. Similarly, the first reflective member 210 can also move down a distance L along the negative X-axis direction perpendicular to the chord surface 213 to the second position. Compared with the initial position, the first Pythagorean reflective surface 211 will reflect the incident earlier Light and the second Pythagorean reflective surface 212 will reflect the incident light earlier. Then the light enters the second reflecting part 240 and is reflected to the image sensor 230 by the second chord surface 243 of the second reflecting part 240. After the light leaves the second reflective component 240, it is offset by a distance of 2L in the negative X-axis direction, which results in a reduction in the focal length, resulting in a shortening of the focal length, and shortening the focal length of the optical system. In this way, moving the first reflecting member 210 along the X axis perpendicular to the chord surface 213 can achieve the effect of adjusting the focal length.

At this time, the imaging position of the light on the image sensor 4204 will not change, and the lens device 4200 only realizes automatic focusing. When the values of L1 and L2 are not equal, the light will deviate from the path before the movement after being reflected by the second reflecting part 4203. At this time, the imaging position of the light on the image sensor 4204 will deviate, relative to the deviation before the movement. The distance is S=|L1-L2|.

Specifically, in the illustrated embodiment, when the first reflective member 4202 and the second reflective member 4203 are moved in the third direction Z in the reverse direction so that the two are far away from each other, when the first reflective member 4202 is in the When the distance L1 moved in the third direction Z is greater than the distance L2 moved in the reverse direction of the second reflective member 4203 in the third direction Z, the imaging position of the light on the image sensor 4204 deviates in the positive direction of the first direction X S=|L1-L2|; when the distance L1 moved by the first reflecting part 4202 in the third direction Z is less than the distance L2 moved backward by the second reflecting part 4203 in the third direction Z, the light beams on the image sensor 4204 The imaging position on the upper side deviates from the negative direction of the first direction X by S=|L1-L2|. In the case where the first reflective member 4202 and the second reflective member 4203 move in the third direction Z in opposite directions so that they are close to each other, when the first reflective member 4202 moves in the third direction Z, the distance L1 is greater than that of the second reflective member 4202. When the reflection part 4203 moves backward in the third direction Z by a distance L2, the imaging position of the light on the image sensor 4204 deviates from the negative direction of the first direction X by S=|L1-L2|; the first reflection part When the distance L1 moved by the 4202 in the third direction Z is less than the distance L2 moved by the second reflecting member 4203 in the third direction Z in the reverse direction, the light S=|L1-L2| deviates from the positive direction of the first direction X by S =|L1-L2|.

The first reflective member 4202 moves in the third direction Z by a distance L1, and the second reflective member 4203 moves in the third direction Z in the same direction by a distance L2. At this time, the imaging position of the light on the image sensor 4204 deviates, relative to The deviation distance before moving is S=L1+L2, thus realizing anti-vibration compensation. Among them, L1 and L2 are absolute values.

When the values of L1 and L2 are not equal, the imaging position of the light on the image sensor 4204 changes, and the deviation distance is S=L1+L2. At this time, between the first lens module 4201 and the image sensor 4204 The optical path of the laser will also change, and the changed distance is △S=|L1-L2|.

Specifically, in the case where the first reflective member 4202 and the second reflective member 4203 move forward by distances L1 and L2 along the third direction Z, when L1>L2, the optical path will increase, and the increased distance is △ S=|L1-L2|; when L1<L2, the optical path will be reduced, and the reduced distance is △S=|L1-L2|. In the case where the first reflecting part 4202 and the second reflecting part 4203 move negatively along the third direction Z by distances L1 and L2, when L1>L2, the optical path will be reduced, and the reduced distance is △S= |L1-L2|; When L1<L2, the optical path will increase, and the increased distance is △S=|L1-L2|.

In this way, the lens device 4200 realizes automatic focusing while realizing anti-vibration compensation.
