Abstract: A fiber core auto-tracing method, system, and storage medium for fabricating fiber gratings. The method includes: acquiring the image of the optical fiber to be processed on the three-dimensional translation stage in real-time; adjusting the relative position of the optical fiber and the microscope objective in the Z-axis direction, until it is recognized that two boundary lines are formed between the fiber core and the cladding in the currently collected image; calculate the position of the center point of the two boundary lines on the three-dimensional translation stage, and adjust the position of the fiber to be processed on the three-dimensional translation stage accordingly until the center point coincides with the XY coordinates of the laser focus. The embodiment of the present invention can quickly and accurately find the center point of the fiber core to be processed through the image recognition technology, so as to ensure processing accuracy, improve the processing quality and success rate, and improve processing efficiency. Since it is mainly implemented in software, the hardware department only needs to use low-cost image sensors, and no major changes to the existing laser fabrication system are required, so the entire solution is cost-effective.

Abstract: An automatic surface tracing method, system, and storage medium are for laser processing. The method includes, at the initial moment, identifying the state of the laser beam on the surface of the workpiece to be processed. If the state is in an out-of-focus state, the relative distance between the microscope objective and the surface of the workpiece to be processed is adjusted, and the state is simultaneously identified until it is identified as an in-focus state. The method for identifying the state of the laser beam includes capturing a position image of the laser beam on the surface of the workpiece to be processed in real-time, and identifying the state of the laser beam accordingly. The method can effectively improve the processing success rate, processing quality and processing accuracy, and is economical and efficient.

Abstract: A radiative cooling film with a surface periodic micro-nano structure can be prepared. The radiative cooling film includes a periodic micro-nano structure layer, a polymer film layer and a reflective coating. The periodic micro-nano structure layer, polymer film layer and the reflective coating can be arranged in a top-down order. Alternatively, the polymer film layer, the periodic micro-nano structure layer and the reflective coating are arranged in a top-down order. A radiation refrigeration film controls the absorption and radiation of the radiative cooling film in the visible light and infrared light bands by adding periodic micro-nano structures on the surface of the polymer film layer. It can increase the infrared radiation to effectively improve the radiative cooling performance and has a high market promotion value.
