In the last 10 years, freeform optics has enabled compact and high-performance imaging
systems. This article begins with a brief history of freeform optics, focusing on imaging …

摘要传统球面以及非球面可供光学系统设计使用的自由度较少. 自由曲面打破了旋转对称以及
平移对称的几何约束, 特别适用于校正非旋转对称系统的像差, 同时可以减少系统中元件的数量 …

This paper utilizes the framework of nodal aberration theory to describe the aberration field
behavior that emerges in optical systems with freeform optical surfaces, particularly φ …

Unobscured optical systems have been in production since the 1960s. In each case, the
unobscured system is an intrinsically rotationally symmetric optical system with an offset …

Building off an earlier work on multinodal third-order aberrations [J. Opt. Soc. Am. A22, 1389
(2005)], this is the first in a series of papers that derives and illustrates the characteristic …

Freeform surfaces play important roles in improving the imaging performance of off-axis
optical systems. However, for some systems with high requirements in specifications, the …

Building on earlier work on the nodal aberration theory of third-order aberrations and a
subset of fifth-order terms, this paper presents the multinodal field dependence of the family …

Building on an earlier work on the nodal aberration theory of the 3rd-order aberrations [J.
Opt. Soc. Am. A22, 1389 (2005)] and the first paper in this series on the nodal aberration …

This paper introduces the path forward for the integration of freeform optical surfaces,
particularly those related to φ-polynomial surfaces, including Zernike polynomial surfaces …

Including free-form optical components in imaging systems provides numerous opportunities
for enhanced performance and compact, lightweight packaging. This applies especially to …
