Description

Technical Field

[0001] This invention relates to the optical decomposition of hydroxyapatite, and more specifically to a novel integrated optical decomposition device for hydroxyapatite based on vortex vector light field modulation technology. Background Technology

[0002] Significant progress has been made in optical field manipulation technology in recent years, particularly in vector optical field manipulation. These techniques have revealed that light possesses not only spin angular momentum but also orbital angular momentum. Utilizing the spin angular momentum of optical fields, researchers have achieved widespread applications in fields such as atomic magnetometers and atomic gyroscopes. Since the first proposal of vortex light in 1989, it has rapidly become an important branch of modern optical research, gaining widespread use due to its unique optical angular momentum and dynamic behavior. Optical manipulation techniques based on the characteristics of vortex light are characterized by high precision, non-destructive operation, and high reliability. This invention utilizes the diffraction mechanism of light, the angular momentum characteristics of vortex beams, and the high precision of a special filtering system to vibrate and disrupt the chemical bonds between deposited hydroxyapatite molecules.

[0003] Prior art includes a photo-vibration decomposition device, see Chinese invention patent "Detection device for SF6 gas decomposition products based on photoacoustic spectroscopy technology", patent application number: CN201420136288.0; a microspherical hydroxyapatite preparation device, see Chinese invention patent "Hydroxyapatite microspheres and preparation method thereof", patent application number: CN201710225034.4; a nanorod-shaped hydroxyapatite preparation device, see Chinese invention patent "A nanorod-shaped hydroxyapatite and preparation method thereof", patent application number: CN201610021197.6; a three-dimensional porous nanostructure hydroxyapatite preparation device, see Chinese invention patent "A three-dimensional porous nano hydroxyapatite and preparation method thereof", patent application number: CN201710284265.2; and a carbon nanotube-reinforced hydroxyapatite composite material preparation device, see Chinese invention patent "A carbon nanotube-reinforced hydroxyapatite composite material preparation method", patent application number: CN200910021361.3.

[0004] Despite the significant advancements and advantages of prior art in the preparation of hydroxyapatite, there are also notable shortcomings: 1) Prior art technologies have not yet addressed the decomposition of hydroxyapatite, particularly in the area of ​​optical decomposition using vector beam excitation. 2) Existing optical decomposition devices are typically bulky, complex, and difficult to maintain, mostly being laboratory-grade equipment. Furthermore, their power and precision are difficult to control flexibly, hindering large-scale application in the medical aesthetics field. 3) Traditional optical or electrochemical methods have slow response times and insufficient precision when processing hydroxyapatite, failing to meet the high-efficiency requirements of emergency situations. 4) Conventional sensors and decomposition techniques require increased sample temperatures when processing hydroxyapatite, increasing operational complexity and hazard. 5) Prior art technologies often lack good compatibility with modern medical equipment, making it difficult to seamlessly integrate hydroxyapatite optical decomposition devices into existing medical systems, thus limiting their widespread application in clinical settings. Summary of the Invention

Specifically, the internal structure of the laser is as follows:

[0007] A reflector is fixed at one end inside the laser, and a xenon lamp is arranged behind the reflector. The xenon lamp contains a gain medium. An X-type analyzer and a beam shaping system are arranged in sequence on the other side of the xenon lamp. A vector vortex waveplate, a beam filtering system, and a coupling output reflector are arranged in sequence on the other side of the beam shaping system.

[0008] In operation, the xenon lamp emits a beam of light towards the reflector. The beam is reflected by the reflector and passes through the x-type analyzer or x-direction polarized light. Then, the beam shaping system obtains a beam conjugate with the vector spiral waveplate, which performs real-time pure phase-level modulation on the beam to obtain a vector spiral beam of arbitrary order with a diameter of 8 to 10 mm. Finally, the vector spiral beam passes through the beam filtering system to obtain the target vector spiral beam.

[0024] The specification of this application contains numerous technical features distributed across various technical solutions. Listing all possible combinations of these features (i.e., technical solutions) would make the specification excessively lengthy. To avoid this problem, the various technical features disclosed in the above-described invention, the various embodiments and examples below, and the various technical features disclosed in the accompanying drawings can be freely combined to form various new technical solutions (all of which are considered to be described in this specification), unless such a combination of technical features is technically infeasible. For example, one example discloses feature A+B+C, and another example discloses feature A+B+D+E. Features C and D are equivalent technical means that serve the same function; technically, only one needs to be used, not both. Feature E can technically be combined with feature C. Therefore, the solution A+B+C+D should not be considered described due to technical infeasibility, while the solution A+B+C+E should be considered described. Attached Figure Description

On the other side of the xenon lamp, an X-type analyzer 3 and a beam shaping system 4 are arranged in sequence. On the other side of the beam shaping system 4, a vector vortex waveplate 5, a beam filtering system 6, and a coupling output reflector 7 are arranged in sequence. The coupling output reflector is made of silver-plated material with a reflectivity greater than 96%. The target area 8 is the surface of human skin that has been injected with hydroxyapatite.

[0038] Optionally, in one embodiment, the reflector 1 is coated with specific phase information and its surface is silver-plated, with a reflectivity greater than 97%. Furthermore, the xenon lamp 2 emits a 100µs pulse with an adjustable repetition frequency between 1 and 2kHz.

[0043] Specifically, the working process of this embodiment is as follows: the light emitted by the xenon lamp 2 passes through the reflector 1, reaches the x-type analyzer 3, and becomes x-direction linearly polarized light. This light then passes through the beam shaping system 4 and the 60th-order vector vortex waveplate 5 to obtain a vector vortex beam of any order with a diameter between 8 and 10 millimeters. This vortex beam passes through the beam filtering system 6 to obtain the final desired vector vortex beam, which is then irradiated onto the surface of the human skin that has been injected with hydroxyapatite via the coupling output reflector 7. Through the above process, this invention achieves the laser-induced synthesis and decomposition of hydroxyapatite. This embodiment realizes the precise synthesis and decomposition of hydroxyapatite without contact with human skin, achieving the purpose of medical aesthetic restoration. In principle, this invention utilizes the high precision of the interference optical path. By modulating a vector vortex laser, the desired vortex beam is obtained and irradiated onto the surface of the skin that has been injected with hydroxyapatite, without contact with the human skin, thereby achieving the precise synthesis and decomposition of hydroxyapatite and achieving the purpose of medical aesthetic restoration. It features simple structure, high sensitivity, easy integration, safety for human body, high consistency of detection results, stable and reliable system, and strong functional expandability.
