“…In this way, the difficulty of assembly is significantly reduced. The design of freeform reflective systems with multiple channels or performances was proposed 15,16 . The mirrors in different channels use different (or partially different) portions of a same mirror, which is represented by one XY polynomials freeform surface.…”

A typical and widely used configuration of freeform imaging system is freeform off-axis three-mirror systems. However, as the system configuration and surface shape have no rotational symmetry, the assembly process will be very difficult. In this paper, we designed off-axis three-mirror systems in which the primary and tertiary mirrors are integrated into one single element. The two mirrors use different portions of a single mirror, which is represented by one mathematical expression. The design process of the system is demonstrated in detail, and three different kinds of light folding geometry are explored. The system design using different types of freeform surface is also explored and the imaging performance is compared. Finally, tolerance analysis which considers the local and random nature of surface error and actual manufacturing difficulty of the freeform surface is conducted.

“…An optical freeform surface is an optical surface that lacks rotational symmetry 11 . Freeform surfaces not only improve the overall performance of optical systems [12][13][14] but also bring novel functions to these systems 15,16 . With advancements in optical processing and testing [17][18][19] , freeform surfaces are feasible in practical application.…”

Design of an optical system, whether classic or novel, in the past or the present, requires significant effort from the designer. In addition to design methods and theories, the designer’s skills and experience in optical system design are particularly important, which may require years of practice to learn. The diversity and variety of results are limited because of the difficulty, time, and labor costs required. In this article, we propose an automatic design method for freeform optics that can achieve a diverse range of three-mirror designs. The optical specifications and the design constraints are the only inputs required, and a variety of results can be obtained automatically. The output results have various structures and various optical power distributions with high imaging qualities. By implementing the design method, designers can not only realize an overview of the solution space of the three-mirror freeform system, but can also focus on specific designs.
