Description

Technical Field

[0001] This application belongs to the field of laser power testing technology, specifically relating to a large-angle multi-band laser power testing device. Background Technology

[0002] Phototherapy, as an effective physical therapy method, is increasingly widely used in the medical field. Treatment devices using different wavelengths of laser light (such as 650nm, 810nm, and 1064nm) are used in clinical settings for anti-inflammation, analgesia, and tissue repair. These medical laser devices typically feature multi-band composite output or high-power, wide-angle light emission. The accuracy and stability of their output power are core parameters ensuring treatment effectiveness and patient safety. Therefore, regular, rapid, and precise optical performance testing of these devices is crucial.

[0003] However, optical performance testing of such devices, especially for multi-band laser sources, is typically designed for single-wavelength lasers. When dealing with treatment devices that simultaneously output multiple wavelengths of laser light, the optical performance testing of laser radiation power requires testing the power of each laser band separately. Multi-band lasers cannot be tested by turning off one wavelength, making it impossible to directly and quickly measure the power of each wavelength. Currently, operators often rely on special operating modes provided by the equipment manufacturer (such as turning off other lasers and keeping only one operating) or manually switching using external filters. This method is heavily dependent on the equipment itself and is inefficient. It is also ineffective for devices that cannot have their lasers switched on and off independently, making true independent verification difficult. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0020] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0021] like Figures 1 to 4 As shown in the embodiment of this application, a large-angle multi-band laser power testing device is proposed, including: a detection device 11, a collimation mechanism 12, and a rotating filter mechanism 13; the collimation mechanism 12 is disposed on the light-incident side of the detection device 11, and the collimation mechanism 12 corrects the incident light into a collimated beam; the rotating filter mechanism 13 is disposed between the detection device 11 and the collimation mechanism 12: the rotating filter mechanism 13 includes a turntable 131 and a plurality of filters 132, the filters 132 are arranged on the turntable 131 along the circumference of the turntable 131, and the filters 132 filter the collimated beam into a single wavelength laser.

[0022] The large-angle multi-band laser power testing device provided in this application includes a detection device 11, a collimation mechanism 12, and a rotating filter mechanism 13. The incident light is a large-angle diverging laser. The incident light is corrected into a collimated beam by the collimation mechanism 12, avoiding measurement errors caused by uneven energy density and increased reflection loss on the surface of the detection device due to excessive incident angle. Multiple bandpass filters 132 of specific wavelengths are arranged circumferentially on the rotating filter mechanism 13. The composite collimated beam is separated by wavelength using the filters 132. By rotating the turntable 131, the target filter 132 is quickly switched into the optical path, filtering out a single wavelength of laser light to enter the detection device 11 for measurement. By continuously rotating and switching the filters 132 in the optical path, multi-band lasers are efficiently separated and measured without frequent disassembly and reassembly of the filters 132 or the need to separately turn off a certain wavelength of laser light, improving the convenience of multi-band laser measurement, increasing testing efficiency, and realizing one-stop detection of large-angle multi-band lasers.

[0023] Understandably, filter 132 only allows high transmittance of laser light of its corresponding wavelength to pass through, while blocking other wavelengths. Each filter 132 has a different wavelength; the bandpass filter 132 achieves the function of measuring only the optical power of a specific wavelength by filtering out other wavelengths of the spectrum. By sequentially switching different wavelength bandpass filters 132 into the optical path, filtering out other wavelengths of the laser spectrum in turn, the detection device 11 receives and measures the power of the monochromatic laser passing through the filter 132, and converts the optical signal into an electrical signal, thereby achieving one-stop detection of multi-band lasers.

[0024] In some examples, the laser under test is first collimated by the collimating mechanism 12, outputting a collimated beam. Then, it passes through a selected wavelength filter 132 in the rotating filter 132 mechanism, becoming a single-wavelength spectrum. This spectrum is then received by the detection device 11 and converted into an electrical signal. After amplification and digitization by the signal processing unit of the detection device 11, the control unit calculates and displays the laser power value at that wavelength. By controlling the sequential rotation of the filter 132 through a program, the laser power in each wavelength band of a multi-band laser can be measured quickly and systematically.

[0025] As a preferred embodiment, the number of filters 132 is at least 8, and the filter group covers at least the red light at 650nm and 810nm, as well as the near-infrared and other common medical wavelengths such as 904nm, 940nm and 1064nm.

[0026] like Figure 3 and Figure 4As shown, in one feasible embodiment, the large-angle multi-band laser power testing device further includes: a guide rail 14, a guide groove 15, and a sliding seat; the guide groove 15 is disposed on two opposite side walls of the guide rail 14 along the length direction of the guide rail 14; the sliding seat includes a plurality of sliders 16, which are extended on the guide rail 14 along the width direction of the guide rail 14, and are slidably connected to the guide groove 15; wherein, the first slider 16 is connected to the detection device 11 so that the detection device 11 is slidably connected to the guide rail 14; the second slider 16 is connected to the collimation mechanism 12 so that the collimation mechanism 12 is slidably connected to the guide rail 14; and the third slider 16 is connected to the rotating filter mechanism 13 so that the rotating filter mechanism 13 is slidably connected to the guide rail 14.

[0027] In this technical solution, an adjustable optical platform is formed through the cooperation of the guide rail 14, the guide groove 15, and the sliding seat. The detection device 11, the collimation mechanism 12, and the rotating filter mechanism 13 can slide independently along the optical path direction, so as to flexibly adjust the relative distance between the detection device 11, the collimation mechanism 12, and the rotating filter mechanism 13 according to the actual light output characteristics and spot size of the light source under test. This not only ensures the coaxial accuracy of the entire optical path system and improves the reliability of the test results, but also enhances the adaptability of the test device to different models and specifications of laser equipment and detection equipment, thereby enhancing the versatility and practicality of the test device.

[0028] like Figures 1 to 4 As shown, in one feasible embodiment, the slider 16 includes: a support plate 161, a first sliding part 162, a second sliding part 163, a contact part 164, and a locking member 165; the first sliding part 162 is connected to a first end of the support plate 161 and is embedded in one of the guide grooves 15; the second sliding part 163 is embedded in the other guide groove 15; the contact part 164 is vertically disposed on the bottom surface of the support plate 161 and is embedded in the second sliding part 163; the locking member 165 is rotatably connected to the second sliding part 163 and is threadedly engaged with the contact part 164 so that the second sliding part 163 presses against the guide groove 15.

[0029] In this technical solution, the first sliding part 162 and the second sliding part 163 are respectively embedded in the guide grooves 15 on both sides of the guide rail 14 to form a stable constraint structure, preventing the sliding seat from deflecting or warping during adjustment; by tightening the locking member 165, the locking member 165 engages with the contact part 164, so as to adjust the distance between the second sliding part 163 and the guide rail 14 by turning the locking member 165; when the locking member 165 drives the second sliding part 163 to move closer to the guide rail 14, the second sliding part The slider 16 is tightly embedded in the guide groove 15, thereby fixing the slider 16 onto the guide rail 14. When the locking member 165 is turned, the second sliding part 163 moves away from the guide rail 14, the pressure and friction between the second sliding part 163 and the guide rail 14 decrease, so as to facilitate the adjustment of the position of the slider 16 on the guide rail 14. The locking structure is easy to operate and reliable in locking, ensuring that each optical mechanism will not be displaced due to accidental contact or vibration after being precisely adjusted, thus ensuring the accuracy and reliability of the measurement results.

[0030] like Figure 3 and Figure 4 As shown, in one feasible embodiment, the detection device 11 includes: a first support column 111, a first adjusting column 112, a detector 113, and a first set screw 114; the first support column 111 is arranged vertically; the first end of the first adjusting column 112 is embedded in the first support column 111, and the first adjusting column 112 is slidably connected to the first support column 111; the detector 113 is disposed at the second end of the first adjusting column 112; the first set screw 114 is threadedly engaged with the first support column 111, and the first set screw 114 presses against the first adjusting column 112 to fix the vertical position of the first adjusting column 112.

[0031] In this technical solution, the vertical adjustment function of the detection device 11 is achieved through the sliding cooperation between the first support column 111 and the first adjustment column 112, and is locked by the first set screw 114 to fix the height of the detector 113. By adjusting the height of the receiving surface of the detector 113, the photosensitive surface of the detector 113 is ensured to be located at the center of the optical path, thereby maximizing the reception of laser energy through the filter 132, optimizing the coupling efficiency of the optical signal, avoiding signal attenuation or measurement deviation caused by the detector 113 deviating from the optical axis, and ensuring the accuracy and reliability of power measurement.

[0032] like Figure 3 and Figure 4As shown, in one feasible embodiment, the collimation mechanism 12 includes: a second support column 121, a second adjusting column 122, a collimating lens 123, and a second setter 124; the second support column 121 is arranged vertically; the second end of the second adjusting column 122 is embedded in the second support column 121, and the second adjusting column 122 is slidably connected to the second support column 121; the collimating lens 123 is disposed at the second end of the second adjusting column 122; the second setter 124 is threadedly engaged with the second support column 121, and the second setter 124 presses against the second adjusting column 122 to fix the vertical position of the second adjusting column 122.

[0033] In this technical solution, the vertical adjustment function of the collimation mechanism 12 is achieved through the sliding cooperation between the second support column 121 and the second adjustment column 122, and is locked by the second set screw 124 to fix the height of the collimation lens 123. By adjusting the collimation lens 123 to the center of the optical path, the optical centers of the collimation mechanism 12, the rotating filter mechanism 13 and the detection device 11 are aligned, ensuring that the collimation lens 123 can effectively receive large-angle divergent beams and efficiently correct them into parallel beams, thus ensuring the collimation effect. This provides a collimated beam with uniform energy distribution and good directionality for subsequent filtering and detection, reducing measurement errors caused by beam quality problems from the source.

[0034] like Figure 3 and Figure 4 As shown, in one feasible embodiment, the rotating filter mechanism 13 includes: a third support column 133 and a mounting base 134; the third support column 133 is arranged vertically; the mounting base 134 is disposed on the third support column 133, and the turntable 131 is rotatably connected to the mounting base 134.

[0035] In this technical solution, the third support column 133 provides a stable mounting base for the mounting seat 134. The mounting seat 134 is used to support and accommodate the turntable 131. The turntable 131 rotates smoothly within the mounting seat 134, so that multiple filters 132 can be quickly switched into the optical path, improving the smoothness and stability of the filter 132 switching process. At the same time, the filter module can be adjusted in position on the guide rail 14 as a whole, improving the integration and reliability of the rotating filter mechanism 13.

[0036] like Figure 4 As shown, in one feasible embodiment, the large-angle multi-band laser power testing device further includes: a threaded rod 17 and a threaded hole; the threaded rod 17 is vertically disposed on the top surface of the third support column 133; the threaded hole is disposed on the bottom surface of the mounting base 134, the threaded hole extends along the height direction of the third support column 133, and the threaded hole is threadedly connected to the threaded rod 17.

[0037] In this technical solution, the threaded rod 17 engages with the threaded hole on the bottom surface of the mounting base 134, allowing the mounting base 134 to be detachably connected to the third support column 133. Simultaneously, the height and angle of the mounting base 134 can be finely adjusted, and the mounting base 134 is locked in place via a self-locking thread. This, combined with the height adjustment of the detection device 11 and the collimation mechanism 12, ensures that each filter 132 on the turntable 131 is aligned with the collimated beam when entering the optical path, further improving the positioning accuracy of filter 132 switching and the transmission efficiency of the entire optical path.

[0038] like Figure 3 and Figure 4 As shown, in one feasible embodiment, the rotating filter mechanism 13 further includes: a set of mounting holes 18, which includes a plurality of mounting holes 18, arranged in a ring array on the turntable 131, and a filter 132 fixed in the mounting holes 18, with each filter 132 corresponding to a mounting hole 18.

[0039] In this technical solution, 18 sets of mounting holes are arranged in a ring array on the turntable 131 to provide standard mounting positions for multiple filters 132. This ensures that the movement trajectory of each filter 132 remains consistent when the turntable 131 rotates, thereby ensuring that the target filter 132 can be aligned with the fixed optical path more quickly when switching filters 132, and improving the convenience of the measurement process.

[0040] like Figure 4 As shown, in one feasible embodiment, the large-angle multi-band laser power testing device further includes: a set of positioning slots 19 and a positioning device 20. The set of positioning slots 19 includes a plurality of positioning slots 19, which are arranged in a ring array on the turntable 131. The positioning slots 19 correspond one-to-one with the mounting holes 18. The positioning device 20 is set on the mounting base 134 and is locked in one of the positioning slots 19.

[0041] In this technical solution, the positioning slot 19 and the positioning device 20 work together to provide indexing and positioning functions for the rotational movement of the turntable 131. Each positioning slot 19 corresponds to the working position of a filter 132. When the turntable 131 rotates and the target filter 132 enters the optical path, the positioning device 20 can automatically engage with the corresponding positioning slot 19 to lock and fix the turntable 131, thereby ensuring that the filter 132 is in the same position during each measurement and that the center of the filter 132 is strictly aligned with the optical path. This further improves the positioning accuracy and reliability, and enhances the repeatability and consistency of multi-band power measurement data.

[0042] like Figure 5As shown, in one feasible embodiment, the positioning device 20 includes: a fixed base 201, a positioning bead 202, and an elastic element 203; the fixed base 201 is arranged perpendicular to the turntable 131 and is embedded in the mounting base 134; the positioning bead 202 is movably disposed in the fixed base 201 and is embedded in a positioning groove 19; the elastic element 203 is disposed in the fixed base 201, with a first end connected to the fixed base 201 and a second end connected to the positioning bead 202 to apply a pushing force to the positioning bead 202.

[0043] In this technical solution, the mounting base 201 provides the installation foundation. When the positioning bead 202 enters the positioning groove 19, the elastic element 203 applies a pushing force to the positioning bead 202, ensuring that the positioning bead 202 will not retract, thus ensuring that the positioning bead 202 can be stably locked into the positioning groove 19. This ensures the stability of the turntable 131 after locking and ensures the repeatability accuracy of the filter 132 switching. When the turntable 131 needs to be rotated, the positioning bead 202 is subjected to the pressure of the positioning groove 19, and the elastic element 203 is compressed by the positioning bead 202, allowing the positioning bead 202 to be released from the positioning groove 19. The turntable 131 can then rotate freely to switch the next filter to the optical path. The turntable 131 can quickly enter or exit the locked state during rotation, making the switching and positioning operation of the filter 132 more convenient and faster.

[0044] Understandably, when the positioning bead 202 is inserted into the positioning groove 19 under the elastic force of the elastic element 203, it will make a "click" sound and form tactile feedback, thereby ensuring that the user can know in time that the center of the filter 132 is strictly aligned with the optical path, further improving the positioning accuracy and reliability of the filter 132.

[0045] It will be readily understood by those skilled in the art that the above embodiments can be freely combined and superimposed without conflict.

[0046] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application. The above are merely preferred embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the protection scope of this application.
