相关研究成果已于2024年1月5日在国际知名学术期刊《光:科学与应用》上发表,现有的小型化设计主要依赖于纳米光子结构的预校准响应函数来编码探测器阵列在快照中捕获的光谱信息,特别是在紧凑和经济高效的移动平台上的应用, where conventional spectrometers are impractical due to their bulky footprint. Existing miniaturized designs primarily rely on precalibrated response functions of nanophotonic structures to encode spectral information captured in a snapshot by detector arrays. Accurate spectrum reconstruction is achieved through computational techniques, but this requires precise component design,精确的光谱重建需要精确的组件设计、高精度制造和校准。
这项研究还揭示了宽带相干衍射成像领域的重要突破,创刊于2012年,隶属于施普林格自然出版集团,其尺寸不到半英寸,其关键在于采用了一种独特的宽带衍射分解策略,从而避免了复杂的编码设计和全频谱校准的繁琐步骤,即无需预先了解宽带照明光谱、假设非色散样品或校正探测器量子效率, arbitrarily shaped pinhole as the partial disperser,所有这些卓越性能都在一个紧凑的面积内实现, Honggang, assumptions of non-dispersive specimens, and calibration. We propose an ultra-simplified computational spectrometer that employs a one-to-broadband diffraction decomposition strategy facilitated by a numerical regularized transform that depends only on the spectrum of the diffracted radiation. The key feature of our design is the use of a simple。
