Description

Technical Field

[0001] This invention relates to a focusing lens assembly and adjustment system and method, specifically to an X-ray focusing lens assembly and adjustment system and method with full field-of-view resolution optimization. Background Technology

[0002] Astronomical observations of space X-rays, planetary remote sensing, and X-ray pulsar navigation typically require optical lenses capable of focusing and imaging space X-rays. Due to its good imaging resolution and relatively easy manufacturing and assembly, the Wolter-I type focusing lens has become a popular configuration for X-ray focusing optical systems. The Wolter-I type focusing lens is composed of a quadratic rotationally symmetric parabolic surface and a hyperboloid confocal surface. X-rays are focused and imaged through two reflections. To increase the effective area of ​​the optical system, a multi-layered nested structure is usually employed. The single-layer lens of the Wolter-I type focusing lens is generally formed by electroforming a high-precision mold after gold plating. To achieve lightweight design, the lens thickness needs to be very thin, typically only 100 micrometers (a few hundred millimeters in height). Such ultra-thin lenses are highly susceptible to deformation under external forces, leading to increased surface shape errors and decreased angular resolution. Furthermore, the assembly and adjustment of the focusing lens requires precise coaxial adjustment of dozens of ultra-thin lens layers, greatly increasing the difficulty of the assembly process. In addition, in order to obtain the optimal angular resolution in the large field of view and the entire field of view, the focusing lens optics need to be specially designed. During the assembly and adjustment process, the angular resolution under different fields of view is further measured. The lens can only be fixed when the angular resolution of the entire field of view reaches the optimal level. Therefore, new challenges are posed to the assembly and adjustment system and method of the focusing lens. Summary of the Invention

[0003] The purpose of this invention is to solve the technical problem that existing Wolter-I type focusing lens assembly and adjustment systems and methods are difficult to make the dozens of ultra-thin lenses in the focusing lens coaxially and precisely assembled and adjusted while maintaining the optimal resolution across the entire field of view. The invention provides an X-ray focusing lens assembly and adjustment system and method with optimized resolution across the entire field of view.

[0004] The technical solution of this invention is:

[0005] The present invention provides an X-ray focusing lens mounting system with full field-of-view resolution optimization for mounting a focusing lens, the focusing lens comprising a focusing lens housing, a focusing hub, and multiple ultra-thin focusing lenses;

[0006] The system includes: an optical platform, a lens mounting and adjustment platform and a lens hoisting assembly mounted on the optical platform, a CCD adjustment and displacement stage mounted on the lens hoisting assembly, a CCD camera mounted on the CCD adjustment and displacement stage, and a light source assembly providing field light for mounting the ultra-thin focusing lens; the optical platform has a first through hole at its center for the focusing lens housing to pass through; the lens mounting and adjustment platform is fixedly mounted on the optical platform and located above the first through hole, and has a second through hole at its center for the ultra-thin focusing lens to pass through, with its lower surface used to connect to the focusing lens housing with a focusing hub; the lens hoisting assembly has multiple suspension lines located above the lens mounting and adjustment platform for hoisting the ultra-thin focusing lens into the corresponding position on the focusing hub; its special feature is:

[0007] The lens mounting assembly includes multiple sets of rigid rings adapted to the outer diameter of multiple ultra-thin focusing lenses of different sizes. Each set of rigid rings includes an upper rigid ring and a lower rigid ring for coaxially sleeved on the upper and lower ends of the corresponding ultra-thin focusing lens.

[0008] The rigid upper ring and the rigid lower ring are respectively bonded and fixed to the upper and lower ends of the corresponding ultra-thin focusing lens;

[0009] The multiple lifting lines of the lens hoisting assembly are respectively connected to the rigid upper ring sleeved on the ultra-thin focusing lens;

[0010] The field light provided by the light source assembly is parallel light, and the adjustable angle between it and the optical axis of the focusing lens is ±5°.

[0011] The CCD adjustment displacement stage is used to adjust the CCD camera to the focal position of the corresponding ultra-thin focusing lens according to different ultra-thin focusing lenses. By adjusting the angle of the field light, different ultra-thin focusing lenses have different defocus amounts.

[0012] The CCD camera is used to image the light spots of different ultra-thin focusing lenses and calculate the corresponding angular resolution.

[0013] Furthermore, the lens mounting assembly includes a disc-shaped mounting platform and multiple lens adjustment assemblies disposed on the lower end face of the mounting platform. The center of the mounting platform is provided with a third through hole corresponding to the second through hole. The multiple lens adjustment assemblies are evenly disposed around the third through hole in the circumferential direction. The third through hole is used for the field light of the light source assembly to pass through and enter the CCD camera.

[0014] Each lens adjustment assembly includes a lens radius adjustment displacement platform, a lens posture adjustment displacement platform, a support structure, guide pulleys, and the suspension line. The lens radius adjustment displacement platform is slidably connected to the lower end face of the hoisting platform, allowing it to move radially to adjust the radial position of the suspension line according to the outer diameter of different ultra-thin focusing lenses. The support structure is fixedly installed on the bottom surface of the lens radius adjustment displacement platform. The lens posture adjustment displacement platform and guide pulleys are respectively located at the outer and inner ends of the support structure. The front end of the suspension line is connected to the lens posture adjustment displacement platform, and the end is bent downwards at a 90-degree angle via the guide pulley to connect with the rigid upper ring sleeved on the ultra-thin focusing lens. The lens posture adjustment displacement platform is used to adjust the height and posture of the ultra-thin focusing lens by extending and retracting the suspension line.

[0015] Furthermore, the light source assembly includes a collimator, a plane mirror, and a precision tilting stage;

[0016] The plane mirror is mounted on a precision tilting stage and is located in the optical path of the light emitted from the collimator.

[0017] The plane mirror is located below the first through hole of the optical platform; the light emitted from the collimator serves as the field light, which is reflected by the plane mirror, enters the focusing mirror housing through the focusing hub, and then enters the CCD camera for imaging after passing through the second through hole of the mirror assembly adjustment platform and the third through hole of the hoisting platform.

[0018] The precision tilting stage is used to adjust the angle between the optical axis of the focusing lens and the field of view by adjusting the tilt angle, and the adjustable range of the angle is ±5°.

[0019] Meanwhile, the present invention also provides a full-field-of-view resolution optimized X-ray focusing lens assembly and adjustment method, which employs the above-mentioned full-field-of-view resolution optimized X-ray focusing lens assembly and adjustment system, and is characterized by including the following method:

[0020] 1) Install the focusing lens housing with the focusing hub onto the lens assembly mounting and adjustment platform, and turn on the light source assembly switch;

[0021] 2) Adjust the lens mounting assembly so that the ends of multiple suspension lines are at the same height and on the same circle, and the size of the circle is adapted to the size of the ultra-thin focusing lens;

[0022] 3) Coaxially mount the rigid upper ring and rigid lower ring, which correspond to the size of the ultrathin focusing lens, to the preset positions at the upper and lower ends of the ultrathin focusing lens;

[0023] 4) Connect the assembled rigid upper ring to the multiple suspension lines of the lens adjustment assembly, and adjust the lens lifting assembly so that the ultra-thin focusing lens falls into the corresponding position of the focusing hub through the second through hole of the lens assembly mounting adjustment platform;

[0024] 5) Adjust the CCD camera to the focal point of the ultra-thin focusing lens using the CCD adjustment displacement stage;

[0025] 6) Adjust the angle between the field light of the light source assembly and the optical axis of the focusing lens within a range of ±5°, and fine-tune the CCD adjustment displacement stage according to the field light so that different ultra-thin focusing lenses have different defocus amounts.

[0026] 7) The ultra-thin focusing lens is imaged by a CCD camera and the angular resolution of the ultra-thin focusing lens under different field of view is calculated. The position of the ultra-thin focusing lens is adjusted by the lens mounting assembly to make its angular resolution optimal in the entire field of view. The ultra-thin focusing lens is fixed on the corresponding position of the focusing hub, and the rigid upper ring and rigid lower ring are removed.

[0027] 8) Repeat steps 2)-7) to install and fix all the ultra-thin focusing lenses on the focusing hub, then remove the focusing lens to complete the installation and adjustment.

[0028] Further, step 2) specifically involves: adjusting the height and position of multiple suspension wires by adjusting multiple lens attitude adjustment displacement stages, so that the ends of multiple suspension wires are at the same height and on the same circle; adjusting multiple lens radius adjustment displacement stages, so that the size of the circle formed by the multiple suspension wires is adapted to the size of the ultra-thin focusing lens.

[0029] The beneficial effects of this invention are:

[0030] 1. This invention discloses an X-ray focusing lens assembly and adjustment system with optimized resolution across the entire field of view. The system comprises a rigid upper ring and a rigid lower ring. The ultra-thin focusing lens is secured at its upper and lower ends using these lightweight yet rigid rings. The lens is then connected to the rigid upper ring via suspension wires in multiple lens adjustment assemblies, rather than directly to the ultra-thin focusing lens. This reduces surface shape variations in the lens and prevents a decrease in angular resolution due to increased surface shape errors. Simultaneously, the CCD adjustment stage can adjust the position of the CCD camera according to the angle of the field of view, allowing different ultra-thin focusing lenses to have different defocus amounts. This ensures that the focusing lens maintains optimal angular resolution across various field of view angles, achieving precise assembly and adjustment of the ultra-thin lens X-ray focusing lens.

[0031] 2. This invention provides a method for assembling and adjusting an X-ray focusing lens with optimized resolution across the entire field of view. First, a lightweight and rigid upper and lower ring is used to constrain the upper and lower ends of the ultra-thin focusing lens, with the rigid upper ring connected to the ultra-thin focusing lens via adhesive tape. Next, the suspension wires in the multiple lens adjustment assemblies are connected to the rigid upper ring. Then, the position and orientation of the ultra-thin focusing lens are adjusted, and a CCD camera is used to image the light spot on the lens, calculating the lens angular resolution. The tilt angle of the precision tilting stage is adjusted to provide a certain angle of field light for assembly, and the position of the CCD camera is finely adjusted so that different lenses have different defocus amounts. This ensures that the focusing lens maintains optimal angular resolution at different field angles, achieving precise assembly and adjustment of an X-ray focusing lens with all ultra-thin lenses.

Detailed Implementation

[0038] The present invention will now be described in detail with reference to embodiments and accompanying drawings.

[0039] This invention discloses an ultrathin X-ray focusing lens assembly and adjustment system optimized for full field-of-view resolution, used to install multiple ultrathin focusing lenses 73 of different sizes in a focusing lens 7. The focusing lens 7 is a Wolter-I type focusing lens, see [link to documentation]. Figure 5 The focusing lens 7 includes a focusing lens housing 71, a focusing hub 72, and multiple ultra-thin focusing lenses 73. The multiple ultra-thin focusing lenses 73 are glued and fixed to the focusing hub 72, which is fixedly mounted on the focusing lens housing 71. To achieve a large field of view and optimized angular resolution across the entire field of view, the lengths of the multiple ultra-thin focusing lenses 73 are gradually varying, meaning the larger-diameter lenses are longer. During lens installation, the focusing hub 72 is installed on the focusing lens housing 71 and then mounted on the lens assembly mounting and adjustment platform 6.

[0040] like Figure 1 As shown, the system of the present invention includes an optical platform 1, a lens assembly mounting and adjustment platform 6 and a lens hoisting assembly 2 mounted on the optical platform 1, a CCD adjustment and displacement stage 3 mounted on the lens hoisting assembly 2, a CCD camera 4 mounted on the CCD adjustment and displacement stage 3, a lens mounting assembly 5, and a light source assembly that provides field light for mounting the ultra-thin focusing lens 73. The optical platform 1 has a first through hole at its center for the focusing lens housing 71 to pass through. The lens assembly mounting and adjustment platform 6 is fixedly mounted on the optical platform 1 and located above the first through hole. It has a second through hole at its center for the ultra-thin focusing lens 73 to pass through, and its lower surface is used to connect to the focusing lens housing 71 with a focusing hub 72. The lens hoisting assembly 2 is equipped with multiple suspension wires 225 and is located above the lens assembly mounting and adjustment platform 6, used to hoist the ultra-thin focusing lens 73 into the corresponding position of the focusing hub 72. The CCD adjustment stage 3 is used to adjust the CCD camera 4 to the focal position of the corresponding ultra-thin focusing lens 73 according to different ultra-thin focusing lenses 73. In order to achieve optimal angular resolution across the entire field of view, the focal positions of different layers of ultra-thin focusing lenses 73 are slightly different. By adjusting the angle of the field light and fine-tuning the CCD adjustment stage 3 according to the angle of the field light, the CCD camera 4 is placed in a suitable defocus position, even though different ultra-thin focusing lenses 73 have different defocus amounts. The CCD camera 4 is used to image the light spots of different ultra-thin focusing lenses 73 and calculate the corresponding angular resolution.

[0041] The lens mounting assembly 5 includes multiple sets of rigid rings adapted to the outer diameters of various ultra-thin focusing lenses 73. Each set of rigid rings includes an upper rigid ring 52 and a lower rigid ring 53, respectively, for coaxially fitting onto the upper and lower ends of the corresponding ultra-thin focusing lens 73. The upper rigid ring 52 and the lower rigid ring 53 are lightweight and have high rigidity. The upper rigid ring 52 and the lower rigid ring 53 are bonded and fixed to the upper and lower ends of the corresponding ultra-thin focusing lens 73, respectively, and are coaxially fitted. The contact surfaces are tangent to the ultra-thin focusing lens 73, which can effectively reduce changes in the surface shape of the ultra-thin focusing lens 73. Multiple suspension wires 225 of the lens lifting assembly 2 are connected to the rigid upper ring 52 fitted onto the ultra-thin focusing lens 73, which can effectively reduce deformation of the ultra-thin focusing lens 73 caused by direct connection.

[0042] The lens mounting assembly 2 includes a disc-shaped mounting platform 21 and multiple lens adjustment assemblies 22 disposed on the lower end face of the mounting platform 21. A third through-hole corresponding to the second through-hole is located at the center of the mounting platform 21. The multiple lens adjustment assemblies 22 are evenly arranged circumferentially around the third through-hole. The third through-hole allows the field light of the light source assembly to pass through and enter the CCD camera 4. Each lens adjustment assembly 22 includes a lens radius adjustment displacement stage 221, a lens attitude adjustment displacement stage 222, a support structure 223, a suspension line 225, and a guide pulley 224. The lens radius adjustment displacement stage 221 is slidably connected to the lower end face of the mounting platform 21, allowing it to move radially to adjust the radial position of the suspension line 225 according to the outer diameter of different ultra-thin focusing lenses 73. The support structure 223 is fixedly disposed on the bottom surface of the lens radius adjustment displacement stage 221. The lens attitude adjustment displacement stage 222 and the guide pulley 224 are respectively disposed at the outer and inner ends of the support structure 223. The front end of the suspension cable 225 is connected to the lens attitude adjustment displacement stage 222, and the end is folded down at a 90-degree angle via the guide pulley 224 to connect to the rigid upper ring 52 fitted on the ultra-thin focusing lens 73. The lens attitude adjustment displacement stage 222 is used to adjust the height and attitude of the ultra-thin focusing lens 73 by retracting the suspension cable 225.

[0043] The field light provided by the light source assembly is parallel light. The light source assembly includes a collimator 8, a plane mirror 9, and a precision tilting stage 10. The plane mirror 9 is mounted on the precision tilting stage 10 and is located in the optical path of the light emitted from the collimator 8; the plane mirror 9 is located below the first through-hole of the optical platform 1. The light emitted from the collimator 8 serves as the field light. After being reflected by the plane mirror 9, it enters the focusing lens housing 71 through the focusing hub 72, and then sequentially passes through the second through-hole of the lens assembly mounting and adjustment platform 6 and the third through-hole of the hoisting platform 21 before entering the CCD camera 4 for imaging. By adjusting the tilt angle of the precision tilting stage 10, a certain angle of field light is provided for the assembly and adjustment. The angle between the field light and the optical axis of the focusing lens 7 is adjustable within a range of ±5°.

[0044] The basic principle of this invention system is:

[0045] First, the upper and lower ends of the ultrathin focusing lens 73 are constrained using a lightweight and rigid upper ring 52 and a rigid lower ring 53. The rigid upper ring 52 is connected to the ultrathin focusing lens 73 by adhesive tape. Second, the suspension wires 225 in the multiple lens adjustment components 22 are connected to the rigid upper ring 52 instead of directly to the ultrathin focusing lens 73, thereby reducing changes in the lens surface shape. Then, the position and pose of the ultrathin focusing lens 73 are adjusted, and the CCD camera 4 is used to image the light spot of the ultrathin focusing lens 73 and calculate the angular resolution. Then, the tilt angle of the precision tilt stage 10 is adjusted to provide a certain angle of field light for the assembly, and the position of the CCD camera 4 is finely adjusted by the CCD adjustment displacement stage 3 so that different lenses have different defocus amounts, thereby ensuring that the focusing lens 7 maintains a good angular resolution at different field angles. Finally, the ultrathin focusing lens 73 is fixed to the focusing hub 72, and the rigid upper ring 52 and rigid lower ring 53 are removed. The operation is repeated to complete the assembly and adjustment of all ultrathin focusing lenses 73.

[0046] Meanwhile, this invention also provides an ultrathin X-ray focusing lens assembly and adjustment method optimized for full field of view resolution, employing the aforementioned ultrathin X-ray focusing lens assembly and adjustment system optimized for full field of view resolution, including the following methods:

[0047] 1) Install the focusing mirror housing 71 with the focusing hub 72 to the mirror assembly mounting and adjustment platform 6, and turn on the collimator 8 switch.

[0048] 2) Adjust the height position of multiple suspension wires 225 by adjusting multiple lens posture adjustment displacement stage 222 so that the ends of multiple suspension wires 225 are at the same height and on the same circle; adjust multiple lens radius adjustment displacement stage 221 so that the size of the circle formed by multiple suspension wires 225 is adapted to the size of the ultra-thin focusing lens 73.

[0049] 3) Coaxially mount the rigid upper ring 52 and rigid lower ring 53, which correspond to the size of the ultrathin focusing lens 73, to the preset positions at the upper and lower ends of the ultrathin focusing lens 73.

[0050] 4) Connect the assembled rigid upper ring 52 to the multiple suspension wires 225 of the lens adjustment assembly 22, and adjust the lens lifting assembly 2 so that the ultra-thin focusing lens 73 falls into the corresponding position of the focusing hub (72) through the second through hole of the lens assembly mounting adjustment platform 6.

[0051] 5) Adjust the CCD camera 4 to the focal position of the ultra-thin focusing lens 73 using the CCD adjustment displacement stage 3.

[0052] 6) Adjust the angle between the field light of the light source assembly and the optical axis of the focusing lens 7 within ±5° (specifically, adjust the tilt angle of the precision tilt stage 10 to rotate the plane reflection mirror 9 by a certain angle so that the field light and the optical axis of the focusing lens 7 form a certain angle, which is adjustable within ±5°), and fine-tune the CCD adjustment displacement stage 3 according to the field light so that different ultra-thin focusing lenses 73 have different defocus amounts.

[0053] 7) The CCD camera 4 is used to image and calculate the angular resolution of the ultrathin focusing lens 73 under different field of view. The pose of the ultrathin focusing lens 73 is adjusted by multiple lens attitude adjustment displacement stages 222 to make it have the optimal angular resolution in the entire field of view. Then, the ultrathin focusing lens 73 is fixed on the corresponding position of the focusing hub 72, and the rigid upper ring 52 and rigid lower ring 53 are removed.

[0054] 8) Repeat steps 2)-7) to install and fix all the ultra-thin focusing lenses 73 onto the focusing hub 72, then remove the focusing lens 7 to complete the installation and adjustment.

[0055] The above-disclosed embodiments are merely specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
