[0047] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0048] Current laser repair monitoring technologies include optical imaging, laser scattering detection, infrared thermal imaging, etc. These technologies have their own advantages and disadvantages. For example, optical imaging technology is very effective for detecting surface defects, but its ability to detect deep defects is limited; laser scattering detection can detect subtle surface changes, but its application on complex surfaces may be limited. Although existing related technologies can meet some basic monitoring needs, in some cases, especially for the detection of tiny defects or deep defects, the accuracy and resolution of existing technologies are still insufficient. At the same time, due to slow processing speeds or data transmission delays, real-time monitoring cannot be achieved.

[0049] The main solution of the embodiment of the present application is to provide a laser repair monitoring device and method, which can detect the axial height change of the sample repair position in real time through the detection module in the laser repair monitoring device, monitor the change of the laser repair position in real time in situ, feedback the laser repair process, and improve the laser repair accuracy.

[0050] The present application embodiment provides a laser repair monitoring device, Figure 1 The overall framework diagram of a laser repair monitoring device provided in an embodiment of the present application is as follows: Figure 1As shown, the laser repair monitoring device 10 includes: an industrial control system 100; a pulse laser 200, which is communicatively connected to the industrial control system 100, and the industrial control system 100 controls the pulse laser 200 to emit a repair laser, which is a pulse laser; a laser repair optical path 300, and the repair laser converges to the sample S through the laser repair optical path 300 to repair the sample S; a detection module 400, which is communicatively connected to the industrial control system 100, and the detection light emitted by the detection module 400 passes through the laser repair optical path 300 to reach the repair position of the sample S, and is reflected from the repair position through the laser repair optical path 300 back to the detection module 400; the detection module 400 includes a detector 410, and the detector 410 detects the reflected detection light in real time.

[0051] The industrial control system 100 is connected in communication with the pulse laser 200, and can control the pulse laser 200 to emit a repair laser to repair the defects of the sample S. The industrial control system 100 is also connected in communication with the detection module 400, and can adjust the detection parameters of the detection module 400 on the one hand, and can also receive the data collected by the detection module 400, analyze and process it, and monitor the repair status of the sample S on the other hand. The industrial control system 100 can be an electronic device with data analysis and processing capabilities, and the embodiment of the present application does not specifically limit the form of the electronic device.

[0052] The pulse laser 200 is used to emit a repair laser in the form of a pulse laser to repair the sample S. Optical devices with different functions are arranged in the laser repair optical path 300 to form an optical path capable of propagating a light beam to the position of the sample S.

[0053] The detection module 400 is used to monitor the repair status of the sample repair position in real time. The detection module 400 includes a detector 410. As the depth position of the sample changes, the position of the reflected detection light on the surface of the detector 410 also changes. The detector 410 can detect the change in the reflection position of the detection light emitted from the detection module 400, and convert and calculate the height change of the sample repair position corresponding to the change in the reflection position of the detection light in combination with the setting of the optical device in the laser repair optical path 300.

[0054] It is understandable that the detector 410 can realize the function of detecting the position change of the detection light in the linear direction. Specifically, any optical detector that can realize the above function can be used as the detector 410, such as a linear array sensor or a planar array sensor. The detection light reflected back to the detection module 400 can form a light spot on the surface of the detector 410, and the change in the position of the light spot can reflect the height change of the repair position of the sample S. Both the linear array sensor and the planar array sensor can detect the position change of the light spot in one-dimensional direction. For cost considerations, the linear array sensor can be used preferentially.

[0055] In some embodiments, referring to Figure 2 , Figure 2 This is a schematic diagram of the structure of a laser repair monitoring device provided in an embodiment of the present application. The detection module 400 also includes a laser pointer 420, a beam splitter prism 430 and a first converging lens 440. The laser pointer 420 emits a detection light, which enters the laser repair optical path 300 after passing through the beam splitter prism 430. The reflected detection light passes through the laser repair optical path 300 to the beam splitter prism 430, is reflected by the beam splitter prism 430 to the first converging lens 440, and converges to the detector 410.

[0056] In the process of the pulse laser 200 emitting a repair laser to repair the sample S, the laser pointer 420 can also emit a detection light, which also reaches the repair position of the sample S through the laser repair optical path 300. It can be understood that the repair laser has a large light diameter, so that the energy is focused on the repair position of the sample S through the converging effect of the laser repair optical path 300 to perform additive or subtractive processing. When designing the optical path of the detection light, the detection light is incident from the position of the axis where the focus is located in the offset laser repair optical path 300, so that after being reflected back to the detection module 400, it is reflected by the dichroic prism 430 to the first converging mirror 440, and reaches the detector 410 under the converging effect of the first converging mirror 440.

[0057] In some practicable embodiments, the detection light emitted by the laser pointer 420 is a continuous laser with a diameter less than 1 mm. For example, the diameter of the continuous laser can be 0.5 mm, 0.6 mm or 0.8 mm. It is understood that a continuous laser with a smaller diameter can meet the needs of real-time monitoring and has high detection accuracy. The wavelength of the continuous laser can be a common laser wavelength, for example, the wavelength can be 405 nm, 532 nm, 633 nm or 1064 nm.

[0058] In some practicable embodiments, the laser repair optical path 300 includes a first reflector 310, an x-direction galvanometer 320, a y-direction galvanometer 330, a first beam splitter 340, a z-direction driver 350, and a second converging lens 360. The laser repair optical path 300 is configured so that light incident from different positions can be converged to the sample S to meet different requirements for repairing, observing, and monitoring the sample S. The second converging lens 360 can be a microscope objective lens.

[0059] The x-direction galvanometer 320 can control the deflection of the light beam in the x-direction, the y-direction galvanometer 330 can control the deflection of the light beam in the y-direction, and the z-direction driver 350 can drive the second converging mirror 360 to move in the z-direction. It can be understood that the x-direction, y-direction and z-direction in the embodiment of the present application are three directions perpendicular to each other in space, and the z-direction usually represents the direction perpendicular to the ground, while the specific directions of the x-direction and the y-direction can be arbitrarily selected. The focal length of the second converging mirror 360 is relatively fixed, and the z-direction driver 350 drives the second converging mirror 360 to move in the z-direction, so that the focus position coincides with the repair position of the sample S, making full use of the energy of the laser.

[0060] In the optical path of the laser repair process, the repair laser is reflected by the first reflector 310 to the x-direction galvanometer 320 after being incident, reflected by the x-direction galvanometer 320 to the y-direction galvanometer 330, reflected by the y-direction galvanometer 330, and reaches the second converging mirror 360 through the first beam splitter 340, and converges to the sample S.

[0061] In the monitoring optical path, after the detection light is incident, it is reflected by the first reflector 310 to the x-direction galvanometer 320, reflected by the x-direction galvanometer 320 to the y-direction galvanometer 330, reflected by the y-direction galvanometer 330, and passes through the first beam splitter 340 to reach the second converging mirror 360, obliquely incident on the sample S, reflected at the repair position, and returned to the detection module 400 along the original optical path.

[0062] It can be understood that in the embodiment of the present application, the repair laser and the detection light are both incident on the laser repair light path 300 from the position of the first reflector 310, but it is not limited to this. Other optical devices with similar functions can also be arranged in the laser repair light path 300, so that the repair laser and the detection light can be incident on the laser repair light path 300 from different positions and finally propagate to the sample S.

[0063] In some practicable embodiments, the laser repair monitoring device 10 further includes a microscopic imaging module 500, which includes an imaging light source 510, a collimating beam expander lens group 520, a second beam splitter plate 530, a tube lens 540, and a camera 550. The microscopic imaging module 500 is used to perform microscopic observation on the sample S, to assist in judging the repair status of the sample S and to determine the repair position of the sample S.

[0064] In the microscopic observation optical path, the imaging light source 510 emits imaging light, which enters the laser repair optical path 300 through the collimating beam expander lens group 520 and the second beam splitter plate 530, reaches the sample S, is reflected by the sample S to the second beam splitter plate 530, and enters the tube lens 540 under the reflection of the second beam splitter plate 530, and reaches the camera 550 for imaging. The collimating beam expander lens group 520 can expand the diameter of the imaging light, reduce the divergence angle, and adjust the imaging light to a parallel state to improve the imaging quality. The imaging light can enter the laser repair optical path 300 from the first beam splitter plate 340, and after being reflected at the sample S, it is reflected by the first beam splitter plate 340 along the original optical path to the second beam splitter plate 530, and returns to the microscopic imaging module 500.

[0065] In some practicable embodiments, the laser repair monitoring device 10 further includes a beam shaping module 600, a second reflector 700, and a third spectroscopic plate 800. The beam shaping module 600 shapes the pulsed laser into a flat-top pulsed laser, which is reflected to the third spectroscopic plate 800 by the second reflector 700 and then reflected to the laser repair optical path 300 by the third spectroscopic plate 800. The spot of the flat-top pulsed laser after shaping is similar to a square spot, has a large single pulse energy, and is suitable for use in laser repair scenarios.

[0066] In some practicable embodiments, the laser repair monitoring device 10 further includes a moving stage 900, which is in communication connection with the industrial control system 100, and the moving stage 900 carries the sample S and moves under the control of the industrial control system 100. The moving stage 900 may have the freedom of movement in the three directions of front and back, left and right, and up and down, and may also be configured with a rotation axis to rotate within a certain angle range to cooperate with the repair of the sample S.

[0067] In this embodiment, as the laser repair process proceeds, the repair position of sample S gradually changes from a defective state to a complete state. As the height of the defective position changes, the detection light emitted by the detection module 400 is converged to the repair position. The height change of the repair position will cause the change in the final reflection position of the detection light. The detector 410 can calculate the height change of the repair position by converting the detected position change, thereby realizing the repair status monitoring of sample S in the depth direction, improving the monitoring accuracy, and realizing real-time detection.

[0068] The present application also provides a laser repair monitoring method, which is applied to the laser repair monitoring device 10 described in the present application embodiment. Figure 3 , Figure 3 This is a flow chart of an embodiment of the laser repair monitoring method of the present application.

[0069] In this embodiment, the laser repair monitoring method includes steps S10 to S40:

[0070] Step S10, determining the repair position of the sample;

[0071] It is understandable that the laser repair monitoring device 10 can be provided with a moving stage or other components capable of carrying the sample S, so that the sample S is close to the exit position of the laser repair optical path 300. The laser repair in the embodiment of the present application may include different repair methods such as additive and subtractive repair methods, which are achieved by controlling the wavelength, energy and other parameters of the laser. The position of the sample S can be observed by the microscopic imaging module 500 or other components with imaging functions to determine the repair position of the sample S. The sample S can also be moved so that the repair position is in the center of the imaging field of view.

[0072] Step S20, setting laser repair parameters through the industrial control system, controlling the pulse laser to emit repair laser, and the repair laser converges to the repair position through the laser repair optical path for repair;

[0073] Laser repair parameters refer to the relevant parameters of the repair laser emitted by the pulse laser 200, which may include the wavelength, energy and other parameters of the repair laser. The industrial control system 100 is in communication connection with the pulse laser 200 and the detection module 400, and can control the pulse laser 200 to emit the repair laser and the detection module 400 to start monitoring.

[0074] Step S30, the detection module detects the axial height change of the repair position in real time;

[0075] It is understandable that both the addition and subtraction of the sample S will produce height changes, and the detection light emitted by the detection module 400 can detect such changes in real time. Figure 4 A schematic diagram of a detection module 400 provided in an embodiment of the present application for detecting axial height changes of a repair position, such as Figure 4 As shown, assuming that during the laser repair process, the axial height change caused by the addition or subtraction of the sample S is s, the change in the center position of the light spot detected by the detector 410 is p, the focal length of the second converging mirror 360 is f1, the focal length of the first converging mirror 440 is f2, the vertical distance between the detector 410 and the focus of the first converging mirror 440 is d, and the distance of the incident light relative to the optical axis is h. According to ray tracing, the following formula 1 can be derived.

[0076] Formula 1:

[0077] Therefore, according to the change p of the center position of the light spot detected by the detector 410, the axial height change of the sample S can be obtained in real time by referring to the following formula 2.

[0078] Formula 2:

[0079] Step S40, when the height of the repair position reaches a preset height, stop the repair, or determine the next repair position of the sample.

[0080] The preset height refers to the target height that the sample S needs to reach for material addition or subtraction. Referring to the above formulas 1 and 2, when s reaches the preset target value s0, and the height of the repair position also reaches the preset height, you can choose to stop the laser repair according to the overall repair situation of the sample S, or determine the next repair position of the sample S, and repeat the above repair process with reference to the above steps.

[0081] The laser repair monitoring method provided in this embodiment is combined with the laser repair monitoring device 10. As the laser repair process proceeds, the repair position of the sample S gradually changes from a defective state to a complete state. As the height of the defective position changes, the detection light emitted by the detection module 400 is converged to the repair position. The height change of the repair position will cause the change in the final reflection position of the detection light. The detector 410 can calculate the height change of the repair position by converting the detected position change, thereby realizing the repair status monitoring of the sample S in the depth direction, improving the monitoring accuracy, and realizing real-time detection.

[0082] The present application also provides an electronic device that can be used as an industrial control system 100, and the electronic device includes: at least one processor; and a memory that is communicatively connected to the at least one processor; wherein the memory stores instructions that can be executed by the at least one processor, and the instructions are executed by the at least one processor so that the at least one processor can execute the laser repair monitoring method in the above-mentioned embodiment.

The communication device 1009 can allow the electronic device to communicate with other devices wirelessly or by wire to exchange data. Although the figure shows an electronic device with various systems, it should be understood that it is not required to implement or have all the systems shown. More or fewer systems can be implemented or have alternatively.
