[0034] In order to enable a person skilled in the art to better understand the features and technical contents of the embodiments of the present disclosure, the implementation of the embodiments of the present disclosure will be described in detail below in combination with the drawings, and the drawings are used for reference only and do not limit the embodiments of the present disclosure. In the following technical description, in order to facilitate explanation, a plurality of details are provided to provide a full understanding of the disclosed embodiments. However, one or more embodiments can still be implemented without these details. In other cases, in order to simplify the drawings, well-known structures and devices can be simplified.

[0035] It should be noted that the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0036] In actual application, the laser light source is used to further quantitatively measure the partial region of interest of the magnetic domain image, and therefore, the following will take the laser as the light for detecting the region of interest of the magnetic domain image to describe the light intensity adjusting device disclosed in the present disclosure.

[0037] In combination with Figures 1 to 6As shown, the light intensity adjusting device provided by the embodiment of the present disclosure comprises a sliding groove 10, a sliding block 20, a positioning assembly and a pull rod 31. The sliding groove 10 is provided with a light-transmitting window 11; the sliding block 20 is used in cooperation with the sliding groove 10 and comprises a positioning groove 21 and a light-transmitting hole 23 provided with a light filtering element 22; wherein the light-transmitting hole 23 penetrates through the side close to the light-transmitting window 11 and the side far away from the light-transmitting window 11, so that the light can pass through the sliding block 20; the light filtering element 22 is arranged in the light-transmitting hole 23 and used for attenuating the light intensity; the positioning assembly comprises the positioning groove 21 arranged on the sliding block 20 and a positioning element 30 used in cooperation with the positioning groove 21. Wherein, when the sliding block 20 is pulled to slide in the sliding groove 10 through pulling the pull rod 31, the light filtering element 22 can be moved, so that the sliding block 20 can shield the light, the light can pass through the light filtering element 22 and the light-transmitting hole 23 and then pass through the light-transmitting window 11 and / or the light can directly pass through the light-transmitting window 11. In the embodiment of the present disclosure, the pull rod 31 can be of any structural form, such as a cylinder or an L-shaped structure, etc. The pull rod 31 can be provided with anti-skid lines to increase the friction between the user or the structure used for pulling the pull rod 31 and the pull rod 31, so as to reduce the relative sliding. The sliding groove 10 can also be of any structural form, such as a hollow cuboid, a hollow cube or a hollow cylinder, etc., as long as the sliding block 20 can slide in the sliding groove 10. In combination with Figure 1 As shown, the sliding groove 10 is a hollow cuboid structure, and the sliding block 20 can slide in the inner cavity of the hollow cuboid. The sliding block 20 is used in cooperation with the sliding groove 10, therefore, the sliding block 20 can be of any structural form which can slide in the sliding groove 10, such as a cuboid, a cube, a cylinder or other structural form matched with the shape and size of the inner cavity of the sliding groove 10.

[0038] In the embodiment of the present disclosure, a plurality of positioning grooves 21 can be arranged on the sliding block 20, such as a first positioning groove, a second positioning groove and / or a third positioning groove, etc. Each positioning groove 21 can correspond to different states of the light intensity adjusting device, such as the third positioning groove corresponding to the laser beam passing through the light filtering element 22 and the light-transmitting hole 23, or the second positioning groove corresponding to the laser beam not passing through the light filtering element 22 and the light-transmitting hole 23, etc.

[0039] In the embodiment of the present disclosure, the light filtering element 22 can be a filter, such as a neutral density filter, an absorption filter or an interference filter, etc.

[0040] In the embodiment of the present disclosure, the light filtering element 22 can be fixed on the sliding block 20 in any way to cover the light-transmitting hole 23. For example, in combination with Figure 2As shown, the light filtering element 22 can be adhered to the sliding block 20 by an adhesive to cover the light transmission hole 23, and the adhesive can include ultraviolet curing adhesive or epoxy resin adhesive, etc. In addition, the light filtering element 22 can be fixed to the sliding block 20 by mechanical clamping. In addition, the light filtering element 22 can be directly pressed into the light transmission hole 23 by pressure. In this way, only the laser beam passing through the light filtering element 22 can irradiate the sample or sample rod through the light transmission hole 23, so as to attenuate the laser light intensity. The shape and size of the light filtering element 22 can be set according to the fixing mode, as long as the light filtering element 22 can cover the light transmission hole 23. For example, when the light transmission hole 23 is fixed by the adhesive, the light filtering element 22 can be any shape and size that can cover the light transmission hole 23, such as a circular shape, a square shape, or other shapes that are larger than the cross-sectional area of the light transmission hole 23. When the light filtering element 22 is pressed into the light transmission hole 23 by pressure, the shape and size of the light filtering element 22 can be the same as or different from the light transmission hole 23, as long as the light filtering element 22 can be clamped in the light transmission hole 23, such as one side of the light filtering element 22 being clamped in the light transmission hole 23 or both sides of the light filtering element 22 being clamped in the light transmission hole 23.

[0041] In addition, in the embodiments of the present disclosure, covering the light transmission hole 23 means covering the possible irradiation position of the laser beam on the cross section of the light transmission hole 23 when the positioning element 30 is inserted into the third positioning groove corresponding to the laser beam passing through the light transmission hole 23. That is, covering the light transmission hole 23 does not require the light filtering element 22 to cover the entire light transmission hole 23, but only requires the light filtering element 22 to cover the possible irradiation position of the laser beam on the light transmission hole 23. The possible irradiation position of the laser beam on the light transmission hole 23 includes the center position of the light transmission hole 23 or any position within a circular region set at a distance from the center position.

[0042] The light intensity adjusting device provided by the embodiments of the present disclosure includes a sliding groove 10, a sliding block 20, and a positioning assembly. The sliding block 20 is used in cooperation with the sliding groove 10 and includes a positioning groove 21 and a light transmission hole 23 provided with a light filtering element 22, and the light filtering element 22 is used to attenuate the laser light intensity. The positioning assembly includes a pull rod 31 connected with the sliding block 20 and a positioning element 30 used in cooperation with the positioning groove 21. During the measurement process, the sliding block 20 can be slid in the sliding groove 10 by pulling the pull rod 31, so that the laser beam passes through the light filtering element 22 and the light transmission hole 23 on the sliding block 20, thereby attenuating the laser light intensity and making the laser light intensity close to the intensity of the illumination of the microscopic imaging. Further, during the measurement process of the sample by the magneto-optical Kerr microscope using the laser light source, the microscopic imaging is realized while the laser spot is displayed, thereby improving the accuracy of the measurement result.

[0043] Optionally, the light transmission window 11 is arranged on the side of the sliding groove 10 away from the light filtering element 22.

[0044] In the embodiments of the present disclosure, the light-transmitting window 11 is mainly used to enable the laser beam to pass through the slide groove 10 to irradiate the sample or sample rod. For example, after the laser beam passes through the light filtering element 22 and the light-transmitting hole 23, the laser beam can continue to pass through the slide groove 10 from the light-transmitting window 11. Alternatively, the laser beam can directly irradiate the sample or sample rod from the light-transmitting window 11 without passing through the light filtering element 22. Therefore, the shape and size of the light-transmitting window 11 can be determined according to the shape and size of the slide block 20, as long as the light-transmitting window 11 can support the slide block 20 to slide in the slide groove 10 and enable the laser beam to pass through the light-transmitting window 11. For example, as shown in FIG. 2, the length of the light-transmitting window 11 is less than the length of the slide block 20, so that the light-transmitting window 11 can support the slide block 20 to slide in the slide groove 10, and the light-transmitting window 11 can cover the light-transmitting hole 23, thereby enabling the laser beam to irradiate the sample or sample rod. Figure 3

[0045] In this way, by arranging the light-transmitting window 11, the laser beam can pass through the light-transmitting window 11 to irradiate the sample after passing through the light filtering element 22 and the light-transmitting hole 23. Alternatively, the laser beam can directly pass through the light-transmitting window 11 to irradiate the sample or sample rod without passing through the light filtering element 22 and the light-transmitting hole 23. In addition, since the pull rod 31 needs to be pulled to drive the slide block 20 to slide in the slide groove 10, if the light-transmitting window 11 is arranged on the side close to the light filtering element 22, the relative movement between the light filtering element 22 on the slide block 20 and the slide groove 10 may cause the light filtering element 22 to be abraded. Therefore, arranging the light-transmitting window 11 on the side away from the light filtering element 22 of the slide groove 10 can avoid the structure part of the slide groove 10 supporting the slide block 20 to slide from abrading the light filtering element 22, thereby prolonging the service life of the light filtering element 22.

[0046] Optionally, the positioning assembly further includes a base 32. The base 32 is connected with the slide groove 10 and includes a first mounting hole 33 for mounting the positioning element 30.

[0047] In this way, the base 32 is connected with the slide groove 10, and the first mounting hole 33 for mounting the positioning element 30 is arranged on the base 32. By arranging the first mounting hole 33 on the base 32, the positioning element 30 can be positioned at the first mounting hole 33 of the base 32 to position the slide block 20 sliding out of the slide groove 10, thereby achieving the attenuation of the laser light intensity.

[0048] Optionally, the base 32 further includes a through hole 34. The through hole 34 is used for passing through the slide block 20. The through hole 34 is in communication with the first mounting hole 33 on the side close to the positioning groove 21, and is used for the positioning element 30 to cooperate with the positioning groove 21 to position the slide block 20.

[0049] In the embodiments of the present disclosure, the positioning element 30 is arranged on the base 32, and the positioning element 30 is arranged on the slide block 20.​Figure 1 As shown, the shape and size of the through hole 34 can be determined according to the shape of the cross section of the slider 20 in the displacement direction. For example, the shape and size of the through hole 34 can be the same as the cross section of the slider 20 in the displacement direction, so as to limit the position of the slider 20 when the slider 20 slides; or the shape and size of the through hole 34 can be different from the cross section of the slider 20 in the displacement direction, for example, the length of the through hole 34 is different from the length of the cross section of the slider 20 in the displacement direction, and the width of the through hole 34 is the same as the width of the cross section of the slider 20 in the displacement direction, which can also limit the position of the slider 20 when the slider 20 slides, so as to reduce the displacement of the slider 20 in the non-displacement direction, thereby ensuring that the positioning element 30 can accurately position the slider 20.

[0050] In this way, the base 32 further comprises the through hole 34 for passing through the slider 20, and the through hole 34 is in communication with the first mounting hole 33 on the side close to the positioning groove 21, so as to position the slider 20 by cooperation of the positioning element 30 and the positioning groove 21. By making the through hole 34 in communication with the first mounting hole 33 on the side close to the positioning groove 21, the positioning element 30 installed in the first mounting hole 33 can accurately position the slider 20 passing through the through hole 34 through the positioning groove 21.

[0051] Optionally, the base 32 further comprises a second mounting hole 35. The second mounting hole 35 is used for connecting the base 32 and the sliding groove 10.

[0052] In this way, the base 32 further comprises the second mounting hole 35 for connecting the base 32 and the sliding groove 10. By providing the second mounting hole 35, the connection between the base 32 and the sliding groove 10 is more stable, and the measurement accuracy is further improved.

[0053] Optionally, the positioning element 30 is a spring ball plunger.

[0054] In this way, the slider 20 is positioned by cooperation of the spring ball plunger and the positioning groove 21, and when the spring ball plunger slides into the positioning groove 21, the slider 20 can be accurately positioned at different positions by the obvious feeling and sound of the spring ball plunger sliding into the positioning groove 21.

[0055] Optionally, the pull rod 31 comprises a mounting seat 36. The mounting seat 36 is arranged on the side of the pull rod 31 close to the slider 20, and comprises a third mounting hole 37 for connecting the slider 20 and the pull rod 31.

[0056] In the embodiments of the present disclosure, the base 32 is arranged on the side of the sliding groove 10 close to the slider 20, and the base 32 comprises the first mounting hole 33 for mounting the positioning element 30, the second mounting hole 35 for connecting the base 32 and the sliding groove 10, and the through hole 34 for passing through the slider 20. Figure 1As shown, the mounting seat 36 can be of any shape and size, as long as it can pull the sliding block 20 out of the through hole 34 while connecting the pull rod 31 and the sliding block 20. For example, the shape and size of the mounting seat 36 can be the same as the cross section of the sliding block 20 in the displacement direction or the through hole 34, or any shape smaller than the cross section of the sliding block 20 in the displacement direction or the through hole 34.

[0057] In this way, the pull rod 31 includes the mounting seat 36 arranged on the side of the pull rod 31 close to the sliding block 20, and the mounting seat 36 includes the third mounting hole 37 for connecting the sliding block 20 and the pull rod 31. By connecting the sliding block 20 and the pull rod 31 through the third mounting hole 37, the connection structure of the sliding block 20 and the pull rod 31 can be more stable, thereby improving the positioning accuracy of the sliding block 20.

[0058] Alternatively, the sliding block 20 further includes the screw hole 24 arranged on the side of the sliding block 20 close to the pull rod 31, which is used in cooperation with the screw 25 to connect the sliding block 20 and the pull rod 31.

[0059] In this way, the sliding block 20 further includes the screw hole 24 arranged on the side of the sliding block 20 close to the pull rod 31, which is used in cooperation with the screw 25 to connect the sliding block 20 and the pull rod 31. By fixing the sliding block 20 and the pull rod 31 through the screw hole 24 and the screw 25, the stability of the connection structure of the pull rod 31 and the sliding block 20 can be improved, thereby improving the positioning accuracy of the sliding block 20.

[0060] Alternatively, the positioning groove 21 includes a first positioning groove and / or a second positioning groove and / or a third positioning groove. The first positioning groove is arranged on the side of the sliding block 20 close to the pull rod 31; wherein when the positioning element 30 is inserted into the first positioning groove, the laser is blocked by the sliding block 20; the second positioning groove is arranged on the side of the sliding block 20 away from the pull rod 31; wherein when the positioning element 30 is inserted into the second positioning groove, the laser does not pass through the light filtering element 22 and directly breaks through the light transmission window 11; the third positioning groove is arranged between the first positioning groove and the second positioning groove; wherein when the positioning element 30 is inserted into the third positioning groove, the laser passes through the light transmission window 11 after passing through the light filtering element 22 and the light transmission hole 23.

[0061] In this way, the first positioning groove is arranged on the side of the sliding block 20 close to the pull rod 31 (the base 32), and in combination with Figure 4 As shown, when the positioning element 30 is inserted into the first positioning groove, at this time the sliding block 20 is completely pushed to the bottom of the sliding groove 10, the laser spot position 40 is on the sliding block 20, and the laser beam does not pass through the light transmission hole 23, so the laser beam is blocked by the sliding block 20, and at this time the laser spot is not displayed at all in the microscopic imaging. The second positioning groove is arranged on the side of the sliding block 20 away from the pull rod 31 (the base 32), and in combination with Figure 6As shown, when the positioning element 30 is inserted into the second positioning slot, the laser spot position 40 is located outside the slider 20 at this time, the laser beam does not pass through the light filtering element 22, the laser beam directly passes through the light transmission window 11, irradiates to the sample to be measured or the sample rod, the laser light intensity is far more than the intensity of the illumination of the microscopic imaging, the laser spot and the microscopic imaging cannot be displayed synchronously, the complete information measurement of the laser spot can be realized, and thus the measurement of the magnetic hysteresis loop of the sample to be measured is realized. Figure 5 As shown, when the positioning element 30 is inserted into the third positioning slot, the laser spot position 40 is located at the center of the light filtering element 22 at this time, the laser beam passes through the light filtering element 22 and the light transmission hole 23, and irradiates to the sample to be measured and the sample rod from the light transmission window 11. The light filtering element 22 plays a role of attenuating the laser light intensity, and thus the synchronous display of the laser spot and the microscopic imaging of the magnetic domain is realized.
