摘要
光子筛是一种在菲涅尔波带片基础上发展起来的新型衍射光学元件。相比于菲涅尔波带片,光子筛可以提高成像系统的信噪比、改善成像质量,具有比其特征尺寸更小的超分辨率;相比于传统的折、反射光学器件,光子筛具有更宽的成像光谱范围。这些优势使得光子筛在空间成像光学领域具有重要的应用前景。介绍了光子筛的计算理论和方法、构型设计、制作技术以及在空间应用方面的研究现状,展望了光子筛的大规模空间应用前景。
Photon sieve is a new type diffractive optical element based on Fresnel zone plate.Compared with Fresnel zone plate,photon sieve can increase the signal-to-noise ratio of imaging system and improve image quality,can have super resolution smaller than its feature size.Photon sieve can also have a wider imaging spectra range compared with traditional refractive and reflective optical devices.These advantages allow photon sieve to have important application prospect in the field of space imaging optics.In this paper,the development of computational theory and method,configuration design,fabrication technology and application of photon sieve were introduced,and large scale application prospect of photon sieve in space was forecasted.
