Description

Technical Field

[0001] This invention relates to the optical decomposition of hydroxyapatite, and more specifically to a novel hydroxyapatite optical decomposition device 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

[0005] The purpose of this invention is to overcome the shortcomings of prior art, fill the gap in the field of hydroxyapatite decomposition, and provide a novel vector beam excited hydroxyapatite optical vibration decomposition device. This device has the characteristics of no mechanical moving parts, simple system structure, extremely high sensitivity and precision, and easy integration.

[0006] This application discloses a novel vector beam-excited hydroxyapatite optical resonator decomposition device. The decomposition device includes a laser, a beam shaping system, an X-direction analyzer, a PBS polarization beam splitter, a spatial light modulator, a vector vortex waveplate, a beam filtering system, an adjustable objective lens, and a target region; wherein:

[0007] The laser is positioned at the beginning of the optical path as a light source and is configured to generate and emit monochromatic tunable laser light.

[0008] The beam shaping system and the X-direction analyzer are arranged sequentially after the laser to receive and adjust the light from the laser.

[0009] The light beam, after passing through the X-direction analyzer, is projected onto the dynamic liquid crystal display screen of the spatial light modulator (SLM) via the PBS polarization beam splitter system, where it undergoes real-time pure phase-level modulation. The modulated beam is then redirected by a mirror in the PBS polarization beam splitter system, projecting onto the vector vortex plate. The vector vortex plate then modulates the beam to generate a vector vortex beam. This vector vortex beam is conjugate with the phase information loaded on the SLM, thereby achieving dynamic modulation of the target vector vortex beam. The target vector vortex beam is then filtered by a high-precision filtering system to obtain the three-dimensional spatial information of the target light field, resulting in a three-dimensionally adjustable beam. This beam is then adjusted by the adjustable objective lens and projected onto the target region. The three-dimensional spatial information includes polarization, phase, amplitude, and spatial position.

[0010] In a preferred embodiment, the laser is characterized in that: the laser is selected from the group consisting of dye lasers, semiconductor tunable lasers, fiber lasers, and free-electron lasers or combinations thereof, and the laser has an extremely narrow image width of less than 0.1 nm and an average power density of 75 mW / cm². 2 .

[0011] In a preferred embodiment, the beam shaping system comprises a freeform lens, wherein the specific material of the freeform lens is selected from the group consisting of silicon dioxide, sodium oxide, and calcium oxide.

[0012] In a preferred embodiment, the X-direction analyzer is selected from the group consisting of polarizers, Wollaston prisms, Nicol prisms, and fiber polarizers.

[0013] In a preferred embodiment, the PBS polarizing beam splitter is characterized by being a cubic PBS made of silicon dioxide, the structure of which consists of two right-angle prisms bonded together by an inclined plane, and one of the right-angle prisms having a polarizing beam splitting film coated on its inclined plane.

[0014] In a preferred embodiment, the spatial light modulator is characterized as a pure phase-type liquid crystal spatial light modulator.

[0015] In a preferred embodiment, the 128th-order vector vortex waveplate is selected from the group consisting of multilayer liquid crystal waveplates using Q-plate technology and holographic grating waveplate-liquid crystal polymer composite waveplates.

[0016] In a preferred embodiment, the beam filtering system comprises a first lens, a second lens, and a filtering device; the first lens and the second lens are freeform lenses made of silicon dioxide with the same focal length; the filtering device is coated with a nanoshell and is mainly made of silicon dioxide and aluminum oxide.

[0017] In a preferred embodiment, the adjustable objective lens is selected from the group consisting of a plan objective lens, a long working distance objective lens, and an ultra-long working distance objective lens, and the adjustable objective lens satisfies that the numerical aperture value is adjustable from 0.1 to 0.5.

[0018] In a preferred embodiment, the target area is characterized by the fact that hydroxyapatite has been injected into the surface layer of human skin.

[0019] In a preferred embodiment, the filter device is coated with a nanoshell structure, and the filter device can change the inner arc circle size by adjusting the diameter of the shell nanoparticles, thereby achieving high-precision filtering.

[0020] The main advantages of this invention are:

[0021] 1) In prior art, optical or electrochemical methods have slow response speed and low precision. However, this device utilizes vortex vector light field control technology and vector diffraction theory to achieve efficient decomposition of hydroxyapatite in emergency situations, meeting the high requirements for speed and precision in surgery, while avoiding heating of the sample and reducing the complexity and danger of operation.

[0022] 2) In the prior art, the preparation and synthesis technology of hydroxyapatite is very mature, but the technology of decomposition is almost blank. This device has a simple structure and is easy to use in medical cosmetic surgery, filling the gap in this key area. At the same time, the use of integrated optical technology ensures the accuracy and stability of the system, making it suitable for large-scale application.

[0023] 3) In prior art for three-dimensional tunable beams, arbitrary positions in free space are typically achieved based on the phase properties of light waves. However, arbitrary polarization control of light waves requires specific Q-plates, complex optical systems, or two-beam interference systems. In two-beam interference systems, the phase polarization is mutually entangled.

[0024] The specification of this application contains numerous technical features distributed across various technical solutions. Listing all possible combinations of these technical 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 technical features disclosed in the following embodiments and examples, 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 have been 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, and technically only one needs to be used; they cannot be used simultaneously. Feature E can technically be combined with feature C. Therefore, the solution A+B+C+D should not be considered as described because it is technically infeasible, while the solution A+B+C+E should be considered as described. Attached Figure Description
