摘要

现在，来自北京理工大学的卞立恒、王震、张宇哲及其同事在《自然》杂志上发表了一篇文章，他们开发了一种片上HS相机，工作光谱范围为400-1,700 nm，光利用率接近75%（卞立恒等）。Nature 635, 73-81；2024)。他们成功的关键是开发了宽带多光谱滤波器阵列（BMSFA），该阵列由含有16种不同的具有宽带吸收的有机化合物的负光刻胶制成。然后，BMSA直接集成在单色成像芯片上，同时神经网络解析高光谱数据立方体以重建高光谱图像（见图中的原理图）。“这样的频谱覆盖非常重要，因为许多应用需要检测在宽带上分布的多个频谱特征。覆盖这样的光谱特征对于高精度的检测和识别是必要的，”该研究的第一作者边立恒评论道。

期刊介绍： Nature Photonics is a monthly journal dedicated to the scientific study and application of light, known as Photonics. It publishes top-quality, peer-reviewed research across all areas of light generation, manipulation, and detection. The journal encompasses research into the fundamental properties of light and its interactions with matter, as well as the latest developments in optoelectronic devices and emerging photonics applications. Topics covered include lasers, LEDs, imaging, detectors, optoelectronic devices, quantum optics, biophotonics, optical data storage, spectroscopy, fiber optics, solar energy, displays, terahertz technology, nonlinear optics, plasmonics, nanophotonics, and X-rays. In addition to research papers and review articles summarizing scientific findings in optoelectronics, Nature Photonics also features News and Views pieces and research highlights. It uniquely includes articles on the business aspects of the industry, such as technology commercialization and market analysis, offering a comprehensive perspective on the field.
