摘要

环形折叠镜头(afl)提供高分辨率单色成像在一个低长焦比包。单片设计提供了优势，但造成了色差。应用自由形状梯度折射率介质可以实现更先进的、衍射受限的单色AFL设计。通过优化GRIN轮廓及其色散，色差也可以得到纠正，从而实现高性能的多色设计。

Design of annular folded lenses using freeform gradient-index optics

Annular folded lenses (AFLs) offer high resolution monochromatic imaging in a low telephoto ratio package. Monolithic designs offer advantages but are inflicted with chromatic aberrations. Applying freeform gradient- index media enables more advanced, diffraction-limited monochromatic AFL designs. By optimizing the GRIN profile along with its dispersion, chromatic aberrations can also be corrected, granting high performing poly- chromatic designs.
