[0037] The therapeutic device body 8 of the present device specifically adopts precise wavelength control and multi-layer filtering technology, which can specifically adopt interference filters, and utilize the interference principle of light, through the superposition of multiple layers of thin films with different refractive indices, so that light of a specific wavelength undergoes constructive interference and is transmitted, and light of other wavelengths undergoes destructive interference and is reflected, thereby realizing precise filtering of light of different wavelengths and achieving the purpose of precise wavelength control;

[0038] Monochromator, which can decompose complex light into a series of monochromatic lights, and can accurately select and output light of a specific wavelength by adjusting the grating or prism and other spectroscopic elements, thus achieving continuous adjustment and precise control of the wavelength;

[0039] Acousto-optic tunable filter AOTF, based on the principle of acousto-optic diffraction, adjusts the wavelength of diffracted light by changing the frequency of the RF signal applied to the acousto-optic crystal. It has the advantages of fast wavelength tuning, narrow bandwidth, high resolution, etc., and can achieve flexible control of the wavelength of light.

[0040] It also has wide-band spectrum coverage and fine control. Specifically, it adopts LED light source arrays with different wavelengths, which are composed of multiple LED chips with different wavelengths. It can cover a wide-band spectrum range from ultraviolet to infrared. By controlling the current or voltage of each LED chip, the output intensity of each wavelength of light can be independently adjusted, thereby achieving the purpose of fine spectrum control.

[0041] Tunable lasers can output lasers with continuously adjustable wavelengths within a certain range. They have the advantages of high brightness, high monochromaticity and high coherence. By changing the internal parameters of the laser, such as cavity length and refractive index, the wavelength of the output laser can be precisely adjusted to meet the needs of different eye treatments for specific wavelengths of light.

[0042] Spectrometer, used to measure and analyze the spectral characteristics of light, can monitor the spectral distribution of the output of the eye treatment device in real time to ensure that the spectral coverage and the intensity of each wavelength of light meet the treatment requirements. By combining with the control system, the output of the light source can be dynamically adjusted according to the feedback information of the spectrometer to achieve precise regulation of the wide-band spectrum;

It can output current or voltage signals of different shapes and amplitudes according to preset programs or algorithms to drive the light source to achieve nonlinear optical power output. By writing a specific control program, it can achieve exponential, logarithmic and other nonlinear optical power change curves to meet the requirements of light intensity at different treatment stages.

[0044] Optical power controller is a device specially used to control optical power. It can accurately adjust the output power of the light source according to the input control signal. Optical power controller usually has the characteristics of fast response, high precision and wide dynamic range. It can realize real-time and accurate control of optical power and realize nonlinear optical power output in combination with nonlinear control algorithm.

[0045] Innovative photon modulation and coupling technology, electro-optic modulator, uses the electro-optic effect to change the refractive index of the crystal by applying an electric field, thereby modulating the phase, amplitude or polarization state of the light passing through the crystal. The electro-optic modulator has the advantages of fast modulation speed, large modulation depth, and good wavelength selectivity, and can achieve fast and accurate modulation of photon frequency and intensity;

[0046] Acousto-optic modulators are based on the principle of acoustic-optical interaction.

The diffuser switching device can be driven by a motor or controlled by an electromagnetic so as to quickly replace different diffusers or adjust the position of the diffuser, thereby changing the divergence angle of the light beam and achieving uniform illumination over a large area or concentrated illumination over a small area.

[0050] The combination of optical reflectors and refractors can achieve functions such as focusing, diverging and steering of light beams by reasonably designing and arranging the positions and angles of the optical reflectors and refractors. By using the combination of reflectors and refractors, a complex optical system can be constructed, and the propagation path and distribution of light can be flexibly adjusted to meet the light diffusion and focusing requirements in different treatment scenarios.

[0051] The working principle of the present invention is: by setting the lower displacement mechanism 2 and the upper displacement mechanism 6 to cooperate with each other, when the fifth motor 24 is started during actual use of the device, it can drive the lower screw rod 23 to rotate inside the guide rail 21. At this time, the lower screw rod 23 will squeeze and drive the movable block 22 to slide back and forth inside the guide rail 21, thereby realizing the adjustment of the front and rear position of the entire therapeutic device body 8. At the same time, the third motor 62 is started to run, and the third motor 62 can drive the upper screw rod 63 to rotate inside the top rail 61. In this way, the upper screw rod 63 can drive the slide plate 64 to slide inside the top rail 61. During the displacement of the movable block 22, the overall structure of the device can achieve forward and backward displacement, and in the therapeutic device During the displacement of the body 8, if the angle adjustment mechanism 7 is started, the upper displacement mechanism 6 can also be assisted in rotation adjustment, so that the therapeutic device body 8 can be conveniently adjusted to face the patient's face. In addition, during this period, if the fourth motor 651 of the rotating assembly 65 is started, the fourth motor 651 can drive the concave seat 652 to rotate, and the rotation of the concave seat 652 will drive the entire upper displacement mechanism 6 and the therapeutic device body 8 to rotate and displace. Through such a design, the therapeutic device body 8 can be adjusted in the front and back and up and down displacement angles during use, so that the device as a whole has a strong adaptability, can accurately adapt to patients of different body shapes, and significantly improves the adaptability of the device during use.

[0052] By setting the mounting mechanism 3, during use of the device, the mounting arm 32 on the fixing plate 31 can be sleeved on the side of the bed, and then the hand-tightened screw rod 33 can be twisted to move it upward. When the hand-tightened screw rod 33 moves upward, it will drive the clamping plate 34 to move upward. At this time, the anti-skid pad 35 on the clamping plate 34 and the anti-skid protrusions on the inner side will fit closely to each other at the side of the bed body, so that the device can be stably mounted on the bed. When the patient needs treatment, he only needs to lie on the bed and adjust it through the lower displacement mechanism 2 and the upper displacement mechanism 6. During this process, if the second motor 54 of the displacement assembly 5 is started to run, The operation of the second motor 54 can drive the gear 55 and the rack 52 to engage in transmission, thereby assisting in driving the slider 51 to move laterally inside the cross rail 4. The lateral displacement of the slider 51 can adjust the position of the therapeutic device body 8. At the same time, during the adjustment period, the first motor 74 is started to drive the hinge shaft 73 inside the hinge seat 72 to rotate. The rotation of the hinge shaft 73 can adjust the therapeutic device body 8 to rotate, so that the therapeutic device body 8 can be tilted close to the patient's face. During this period, the upper displacement mechanism 6 is started to drive the therapeutic device body 8 to move forward and backward, and then the therapeutic device body 8 can be adjusted in front and back, left and right, and up and down angles. It can better adapt to the patient's face, and in the process of adjustment, the patient's face can be scanned and detected by the 3D structured light face sensor 9, which can identify the position of the patient's face, and then adjust it in conjunction with the single-chip controller and the lower displacement mechanism 2, the upper displacement mechanism 6 and the displacement component 5, so that it can accurately adapt to the patient's face and have the function of automatic adjustment, which greatly improves the detection and adaptation performance of the device during the overall practical period; the 3D structured light face sensor 9 can accurately scan and detect the position information of the patient's face, and this information will be transmitted to the single-chip controller, which is like the entire system The "brain" analyzes and processes the received facial position data, and then, through the coordinated work of the lower displacement mechanism 2, the upper displacement mechanism 6 and the displacement component 5, including the second motor 54 driving the gear 55 and the rack 52 to make the slider 51 displace laterally, the first motor 74 driving the hinge shaft 73 to rotate to tilt the therapeutic device, and the upper displacement mechanism 6 driving the therapeutic device to move forward and backward, etc., the therapeutic device can be adjusted in multiple directions such as front and back, left and right, and up and down, so that the therapeutic device can automatically fit the patient's face and eyes. This automatic adjustment function reduces the complexity and uncertainty of manual operation and improves the accuracy and efficiency of fitting.
