Description

Technical Field

[0001] Embodiments of the present disclosure relate to the field of laser technology, and in particular to a laser output device and a laser output method. Background Art

[0002] In recent years, the proportion of medical aesthetic energy source medical aesthetics (photoelectric medical aesthetics) in the medical aesthetics equipment market has become increasingly important. With the development of medical aesthetics equipment, various laser output devices have emerged. Laser output devices are devices used to output lasers. At present, existing laser output devices for laser treatment are usually laser output devices based on lamp-pumped lasers.

[0003] However, the above-mentioned laser output devices based on lamp-pumped lasers often have the following technical problems:

[0004] First, during the operation of a lamp-pumped laser output device, due to the excitation of a pump lamp (such as a flash lamp), the laser medium (such as an Nd:YAG crystal) absorbs a large amount of energy and generates light radiation, but also releases a large amount of heat. In order to reduce the damage to the laser output device caused by the released heat, the laser output device based on the lamp-pumped laser is often equipped with a cooling device, which not only increases the space occupied by the laser output device, but also increases the power consumption of the laser output device (for example, power consumption). At the same time, the lamp-pumped laser relies on a high-intensity flash lamp to excite the laser medium, and this flash lamp will gradually decay over time, resulting in a shorter service life of the laser output device based on the lamp-pumped laser.

[0005] Next, the inventor discovered that when the laser output device disclosed in the present invention outputs laser for treatment, there are further technical problems as follows:

[0006] Second, when the laser output device outputs the laser to the area where the target object is located, the target object may leave the preset target irradiation area during the laser irradiation process (for example, when the target object during the laser output treatment is a child, the child may slightly move the treatment part (i.e., the target object, such as a finger or ear) away from the preset target irradiation area due to hyperactivity or discomfort caused by the laser treatment), making it difficult for the doctor to find that the target object has left the preset target irradiation area, thereby resulting in poor treatment effect of the laser output device. At the same time, when the target object leaves the preset target irradiation area for treatment, continuing to output the laser will cause ineffective irradiation, resulting in increased energy waste of the laser device.

Specifically, the reason for the high power consumption and short service life of the laser output device is that during the operation of the laser output device based on the lamp pump laser, due to the excitation of the pump lamp (such as a flash lamp), the laser medium (such as Nd:YAG crystal) absorbs a large amount of energy and generates light radiation, but also releases a large amount of heat. In order to reduce the damage to the laser output device caused by the released heat, the laser output device based on the lamp pump laser is often equipped with a cooling device. The cooling device not only increases the space occupied by the laser output device, but also increases the power consumption (for example, power consumption) of the laser output device. At the same time, the lamp pump laser relies on a high-intensity flash lamp to excite the laser medium. This flash lamp will gradually decay over time, resulting in a short service life of the laser output device based on the lamp pump laser. Based on this, the laser output device of some embodiments of the present disclosure includes: a power supply component, a detachable main body bracket, a semiconductor pump laser, a light guide arm, a touch screen control device, an emergency stop switch, and a key switch. Since the laser in the laser output device replaces the lamp pump laser with a semiconductor pump laser. The solid-state laser medium used in the semiconductor pump laser is relatively stable and will not gradually decay over time, thereby increasing the service life of the laser output device. The power supply assembly provides power for the laser output device. The detachable main bracket is used to fix the power supply assembly, the semiconductor pump laser, the touch screen control device, and the key switch. The light guide arm is connected to the semiconductor pump laser through a detachable connector. The semiconductor pump laser includes a water-free semiconductor laser output module for generating laser. Since the semiconductor pump laser adopts a water-free semiconductor laser output module, there is no need to equip an additional cooling device, which reduces the space occupied by the laser output device and reduces the additional power consumption of the laser output device caused by the cooling device. The light guide arm is used to transmit the laser generated by the semiconductor pump laser to the preset target irradiation area. The touch screen control device is used to control the output time of the laser generated by the semiconductor pump laser, and control the semiconductor pump laser to generate laser corresponding to the laser parameter information. The emergency stop switch is connected to the touch screen control device to control the semiconductor pump laser to stop generating laser light. The key switch controls the power switch of the power supply assembly to turn the laser output device on and off. Because the laser output device uses a semiconductor pump laser, the service life of the laser output device is extended compared to the lamp pump laser.At the same time, the semiconductor pump laser adopts a water-free cooling semiconductor laser output module to solve the heat released in the laser generation process. There is no need to install additional cooling devices, which reduces the space occupied by the laser output equipment and the additional power consumption of the laser output equipment caused by the cooling device.

For example, the above-mentioned connector can be but not limited to one of the following: a screw, an optical connector. The above-mentioned semiconductor pump laser 3 includes a water-free semiconductor laser output module for generating laser.

In order to achieve this effect, the present disclosure adopts a design in which a dust sensor and a gas cleaning nozzle are embedded in the inner surface of the light guide arm in the laser input device.

[0037] Figure 3 The schematic diagram of the structure of some embodiments of the laser gain module of the present disclosure is shown. Optionally, each of the stack pump amplifiers includes a first-stage stack pump amplifier 51 and a second-stage stack pump amplifier 56, and the laser gain module includes a first polarizer 42, a beam expander 43, an optical rotator 44, a collimator 45, a second polarizer 46, an aperture 47, a first reflector 48, a second reflector 49, a polarization reflector 50, a first-stage stack pump amplifier 51, a wave plate 52, a third reflector 53, a fourth reflector 54, a fifth reflector 55, a second-stage stack pump amplifier 56, a frequency doubling crystal 57, a first filter 58, a second filter 59, and a laser window 60.

[0039] Optionally, a camera is installed at a preset position of the light guide arm 4 .

[0040] Reference below Figure 4 , Figure 4 The laser output method applied to a touch screen control device according to the present disclosure is shown. The laser output method comprises the following steps:

[0041] Step 401, in response to receiving information sent by a key switch indicating that a laser output device is turned on, playing a voice message for wearing laser goggles.

[0042] In some embodiments, the execution subject of the laser output method (e.g., a touch screen control device) can play a voice message for wearing laser goggles in response to receiving the information sent by the key switch indicating that the laser output device is turned on. The information indicating that the laser output device is turned on can be an electrical signal.

[0043] Step 402, displaying the laser output page.

[0044] In some embodiments, the execution subject may display a laser output page. The laser output page includes a laser goggles selection control. The laser output page may be a page for configuring various laser parameters, laser output start time, and laser output end time. The various laser parameters may include but are not limited to the following: laser wavelength, output energy power, and polarization characteristics. The laser goggles selection control may be a page interaction element for interface interaction operations to indicate that laser goggles have been worn.

[0045] Step 403, in response to detecting a selection operation acting on the selection control of the worn laser goggles, various laser parameter input boxes, a start time input box, and an end time input box are displayed in a first preset display area of ​​the laser output page.

[0046] In some embodiments, the execution subject may display various laser parameter input boxes, start time input boxes, and end time input boxes in the first preset display area of ​​the laser output page in response to detecting a selection operation acting on the worn laser goggles selection control. Each of the laser parameter input boxes in the various laser parameter input boxes may be an input box for inputting laser parameters. The start time input box may be an input box for inputting the start time of laser output. The end time input box may be an input box for inputting the end time of laser output.

[0047] Step 404 , in response to detecting input operations acting on each laser parameter input box, determining each input information corresponding to each laser parameter input box as laser parameter information.

[0048] In some embodiments, the execution subject may determine each input information corresponding to each laser parameter input box as laser parameter information in response to detecting an input operation acting on each laser parameter input box.

[0049] Step 405: In response to detecting an input operation acting on the start time input box, the input information corresponding to the start time input box is determined as the start time.

[0050] In some embodiments, the execution entity may determine the input information corresponding to the start time input box as the start time in response to detecting an input operation acting on the start time input box.

[0051] Step 406: In response to detecting an input operation acting on the end time input box, the input information corresponding to the end time input box is determined as the end time.

[0052] In some embodiments, the execution subject may determine the input information corresponding to the end time input box as the end time in response to detecting an input operation acting on the end time input box.

[0053] Step 407: Display a configuration completion control in the second preset display area of ​​the laser output page.

[0054] In some embodiments, the execution subject may display a configuration completion control in the second preset display area of ​​the laser output page, wherein the configuration completion control may be a page interaction element for determining whether the configuration is completed.

[0055] Step 408 , in response to detecting a selection operation acting on the configuration completion control, controlling the semiconductor pump laser to generate laser corresponding to the laser parameter information within a time period corresponding to the start time and the end time.

[0056] The above-mentioned various embodiments of the present disclosure have the following beneficial effects: through the laser output method applied to the above-mentioned touch screen control device in some embodiments of the present disclosure, the user experience is improved. Specifically, the reason for the poor user experience is that the traditional laser output device may only output lasers with fixed parameters. If the parameters of the laser output of the laser device are to be changed, it may be necessary to replace the hardware device (for example, replace different optical filters) or mechanically adjust the laser parameters (for example, the user's hand uses a mechanical knob to gradually rotate and adjust) the laser parameters, which is cumbersome to operate, resulting in a poor user experience. Based on this, the laser output method of the touch screen control device in some embodiments of the present disclosure includes: first, in response to receiving the information sent by the key switch that represents the opening of the laser output device, playing a voice of wearing laser goggles. Thus, the user can be notified to wear laser goggles before laser irradiation. Then, the laser output page is displayed, wherein the above-mentioned laser output page includes a selection control for wearing laser goggles. Thus, a laser output page for configuring laser parameter information can be displayed. Then, in response to detecting the selection operation acting on the above-mentioned laser goggles selection control that has been worn, each laser parameter input box, start time input box, and end time input box are displayed in the first preset display area of ​​the above-mentioned laser output page. Afterwards, in response to detecting the input operation acting on the above-mentioned laser parameter input boxes, the input information corresponding to the above-mentioned laser parameter input boxes is determined as laser parameter information. Thus, the laser parameter information can be configured through interface interaction. Afterwards, in response to detecting the input operation acting on the above-mentioned start time input box, the input information corresponding to the above-mentioned start time input box is determined as the start time. Then, in response to detecting the input operation acting on the above-mentioned end time input box, the input information corresponding to the above-mentioned end time input box is determined as the end time. Thus, the start time and end time of the laser output can be obtained. Afterwards, the configuration completion control is displayed in the second preset display area of ​​the above-mentioned laser output page. In response to detecting the selection operation acting on the above-mentioned configuration completion control, the above-mentioned semiconductor pump laser is controlled to generate a laser corresponding to the above-mentioned laser parameter information in the time period corresponding to the above-mentioned start time and the above-mentioned end time. Also, because the laser parameter information of the output laser can be configured interactively through the interface, the user is allowed to adjust the output parameters of the laser in real time according to specific application scenarios and needs. Compared with physical control panels or mechanical adjustment parameters, the operation is more convenient and efficient, which improves the user experience.

[0057] In some embodiments, the execution subject may control the semiconductor pump laser to generate laser corresponding to the laser parameter information in a time period corresponding to the start time and the end time in response to detecting a selection operation acting on the configuration completion control.

[0058] In some optional implementations of some embodiments, after controlling the semiconductor pump laser to generate laser corresponding to the laser parameter information within the time period corresponding to the start time and the end time, the execution subject may further perform the following steps:

[0059] The first step is to obtain the target object image. In practice, the execution subject can obtain the target object image from a preset storage location. The target object image can be an image of the treatment part collected in advance before the laser output device outputs the laser. The preset storage location can be a storage location of the touch screen control device for storing the target object image.

[0060] The second step is to perform feature extraction processing on the target object image to obtain first feature extraction information corresponding to the target object image. In practice, the execution subject can extract the features of the target object image through an image feature extraction model to obtain the first feature extraction information. The first feature extraction information can be a feature vector that characterizes the target object image.

[0061] The third step is to perform the following control steps based on the first feature extraction information:

[0062] Sub-step 1: Get system time.

[0063] Sub-step 2: in response to determining that the system time is before the end time, based on the system time, performing the following steps:

[0064] In the first sub-step, an image of the preset target irradiation area is collected as a target image by a camera located at a preset position of the light guide arm. The target image includes an image of the target area and an image of a non-target area (e.g., a background area). The target area may be an area where a target object may exist. The target object may be a laser irradiation object (i.e., a laser treatment site).

[0065] The second sub-step is to perform denoising on the target image to obtain a denoised target image. In practice, the execution subject may perform denoising on the target image by using a Gaussian filter algorithm to obtain a denoised target image.

[0066] The third sub-step is to perform threshold segmentation processing on the denoised target image to obtain target region information of the target region where the target object is located. The target region information can be represented by various coordinate points.

[0067] The fourth sub-step is to perform the following update process for each pixel in the denoising target image:

[0068] Sub-step 1: determining the number of color channels of the pixel to be a preset value, wherein the preset value may be 1.

[0069] Sub-step 2: in response to determining that the pixel point is within the area corresponding to the target area information, determining the pixel value of the pixel point as a first preset pixel value to update the pixel point. The first preset pixel value may be 1.

[0070] Sub-step three: in response to determining that the pixel point is not in the area corresponding to the target area information, the pixel value of the pixel point is determined to be a second preset pixel value to update the pixel point. The second preset pixel value may be 0.

[0071] In the fifth sub-step, each pixel in the denoising target image is determined as a denoising target area mask image by updating the denoising target image.

[0072] The sixth sub-step is to generate an initial target area image based on the denoised target image and the denoised target area mask image. In practice, the above-mentioned execution subject can perform a bitwise AND operation on the denoised target image and the denoised target area mask image to obtain the initial target area image. As an example, the pixel values ​​of the pixels in the denoised target area mask image that are not in the area corresponding to the target area information are determined to be 0 and the pixel values ​​of the pixels in the denoised target image that are not in the area corresponding to the target area information are represented by a bitwise AND operation to update the pixel values ​​of the pixels in the denoised target image that are not in the area corresponding to the target area information to (0, 0, 0). The pixel values ​​of the pixels in the area corresponding to the target area information in the denoised target area mask image are determined to be 1 and the pixel values ​​of the pixels in the area corresponding to the target area information in the denoised target image are represented by a bitwise AND operation to update the pixel values ​​of the pixels in the area corresponding to the target area information in the denoised target image to the original values ​​without any change.

[0073] The seventh sub-step is to perform foreground extraction and cropping processing on the initial target area image to obtain the target area image. In practice, the execution subject can crop and remove the corresponding image of each pixel point with a pixel value of (0, 0, 0) in the initial target area image from the initial target area image to obtain a cropped target area image.

[0074] In an eighth sub-step, feature extraction is performed on the target area image to obtain second feature extraction information corresponding to the target area image. In practice, the execution subject may input the target area image into the image feature extraction model to obtain the second feature extraction information. The second feature extraction information may be a feature vector representing the target area image.

[0075] The ninth sub-step is to generate object out-of-bounds detection information based on the first feature extraction information and the second feature extraction information. In practice, first, the execution subject may determine the similarity between the first feature extraction information and the second feature extraction information. Then, in response to determining that the similarity is less than a preset threshold, the execution subject may determine the information characterizing that the target object has left the irradiation area as the object out-of-bounds detection information. The object out-of-bounds detection information may be text information. The similarity may be cosine similarity.

[0076] A tenth sub-step is, in response to determining that the object out-of-bounds detection information indicates that the target object has left the irradiation area, executing the following pause processing steps:

[0077] Sub-step 1: Playing a voice indicating that the target object leaves the irradiated area.

[0078] Sub-step 2: Control the semiconductor pump laser to stop generating laser light, and display the system time as the pause time in the third preset display area of ​​the laser output page.

[0079] In the eleventh sub-step, in response to determining that the object out-of-bounds detection information indicates that the target object has not left the irradiated area, the above control step is executed again after a preset time period of the system time.

[0080] The above technical solution and its related contents, as an inventive point of the embodiment of the present disclosure, solve the second technical problem mentioned in the background technology: "When the laser output device outputs the laser to the area where the target object is located, the target object may leave the preset target irradiation area during the laser irradiation process (for example, when the treatment object is a child during the laser output treatment process, the child may slightly move the treatment part (that is, the target object, such as a finger or ear) away from the preset target irradiation area due to hyperactivity or discomfort caused by the laser treatment), which makes it difficult for the doctor to find that the target object has left the preset target irradiation area, thereby resulting in poor treatment effect of the laser output device. At the same time, when the target object leaves the preset target irradiation area of ​​the treatment, the target object may be left behind. Continuous output of laser will cause ineffective irradiation, resulting in increased energy waste of laser equipment. If the above factors are solved, the effect of reducing energy waste of laser equipment can be achieved. In order to achieve this effect, first, an image of the target object is acquired. Thus, an image of the target object (for example, the treatment site) can be obtained. Then, feature extraction processing is performed on the above target object image to obtain first feature extraction information corresponding to the above target object image. Thus, first feature extraction information characterizing the characteristics of the target object can be obtained. Afterwards, based on the above first feature extraction information, the following control steps are performed: Obtain system time. Then, in response to determining that the system time is before the above end time, based on the system time, the following steps are performed: By position extraction, the system time is obtained. The camera at the preset position of the light guide arm captures the image of the preset target irradiation area as the target image. Thus, the image of the preset target irradiation area can be captured as the target image during the laser output device outputs the laser. Afterwards, the target image is denoised to obtain a denoised target image. Thus, the image quality of the captured target image can be improved to obtain a denoised target image. Next, the denoised target image is threshold segmented to obtain target area information of the target area where the target object is located. Thus, the target area information corresponding to the area where the target object may exist can be obtained. Afterwards, for each pixel in the denoised target image, the following update process is performed: the number of color channels of the pixel is determined to be a preset value . In response to determining that the pixel point is within the area corresponding to the target area information, the pixel value of the pixel point is determined to be a first preset pixel value to update the pixel point. In response to determining that the pixel point is not within the area corresponding to the target area information, the pixel value of the pixel point is determined to be a second preset pixel value to update the pixel point. The denoised target image after the update processing of each pixel in the denoised target image is determined as a denoised target area mask image. Thus, the denoised target area mask image can be used to generate the initial target area image. Afterwards, the initial target area image is generated based on the denoised target image and the denoised target area mask image. Afterwards, the initial target area image is subjected to foreground extraction and cropping processing to obtain the target area image.Thus, through foreground extraction and cropping processing, an image in the target area is generated, that is, a target area image with the non-target area (background area) image removed, so as to reduce the interference of the non-target area image on the generation of object out-of-bounds detection information. Afterwards, the target area image is subjected to feature extraction processing to obtain second feature extraction information corresponding to the target area image. Thus, the second feature extraction information characterizing the characteristics of the target area image can be obtained. Then, based on the first feature extraction information and the second feature extraction information, object out-of-bounds detection information is generated. Thus, object out-of-bounds detection information characterizing whether the target object leaves the target area (preset target irradiation area) can be generated. Then, in response to determining that the object out-of-bounds detection information characterizes that the target object leaves the irradiation area, the following pause processing step is performed: play a voice characterizing that the target object leaves the irradiation area. Thus, the doctor can be reminded by voice playback that the target object leaves the preset target irradiation area. Afterwards, the semiconductor pump laser is controlled to stop generating laser light, and the system time is displayed as the pause time in the third preset display area of ​​the laser output page. Thus, when the target object leaves the preset target irradiation area, the rope threading laser can be paused in time to reduce invalid irradiation and reduce the increase in energy waste of the laser equipment. In response to determining that the object departure detection information indicates that the target object has not left the irradiation area, the above control steps are performed again after a preset time period of the system time. Since the target image of the preset target irradiation area is collected during the laser output process, the object departure detection information is generated based on the target image. When the object departure detection information indicates that the target object has left the irradiation area, a pause process is performed to reduce ineffective irradiation and reduce the increase in energy waste of the laser device.

[0081] The above-mentioned embodiments of the present disclosure have the following beneficial effects: through the laser output device of some embodiments of the present disclosure, the power consumption of the laser output device can be reduced and the service life of the laser output device can be improved. Specifically, the reason for the high power consumption and short service life of the laser output device is that during the operation of the laser output device based on the lamp pump laser, due to the excitation of the pump lamp (such as a flash lamp), the laser medium (such as Nd:YAG crystal) absorbs a large amount of energy and generates light radiation, but also releases a large amount of heat. In order to reduce the damage to the laser output device caused by the released heat, the laser output device based on the lamp pump laser is often equipped with a cooling device. The cooling device not only increases the space occupied by the laser output device, but also increases the power consumption (for example, power consumption) of the laser output device. At the same time, the lamp pump laser relies on a high-intensity flash lamp to excite the laser medium. This flash lamp will gradually decay over time, resulting in a short service life of the laser output device based on the lamp pump laser. Based on this, the laser output device of some embodiments of the present disclosure includes: a power supply component, a detachable main body bracket, a semiconductor pump laser, a light guide arm, a touch screen control device, an emergency stop switch, and a key switch. Since the laser in the laser output device replaces the lamp pump laser with a semiconductor pump laser. The solid-state laser medium used in the semiconductor pump laser is relatively stable and will not gradually decay over time, thereby increasing the service life of the laser output device. The power supply assembly provides power for the laser output device. The detachable main bracket is used to fix the power supply assembly, the semiconductor pump laser, the touch screen control device, and the key switch. The light guide arm is connected to the semiconductor pump laser through a detachable connector. The semiconductor pump laser includes a water-free semiconductor laser output module for generating laser. Since the semiconductor pump laser adopts a water-free semiconductor laser output module, there is no need to equip an additional cooling device, which reduces the space occupied by the laser output device and reduces the additional power consumption of the laser output device caused by the cooling device. The light guide arm is used to transmit the laser generated by the semiconductor pump laser to the preset target irradiation area. The touch screen control device is used to control the output time of the laser generated by the semiconductor pump laser, and control the semiconductor pump laser to generate laser corresponding to the laser parameter information. The emergency stop switch is connected to the touch screen control device to control the semiconductor pump laser to stop generating laser light. The key switch controls the power switch of the power supply assembly to turn the laser output device on and off. Because the laser output device uses a semiconductor pump laser, the service life of the laser output device is extended compared to the lamp pump laser.At the same time, the semiconductor pump laser adopts a water-free cooling semiconductor laser output module to solve the heat released in the laser generation process. There is no need to install additional cooling devices, which reduces the space occupied by the laser output equipment and the additional power consumption of the laser output equipment caused by the cooling device.
