自由曲面光学已经成为光学行业中最突出的元素。先进的自由形状光学设计与超精密制造和计量技术相辅相成，提升了现有人类的生活方式、思维和观察力。与太空探索、便携性、可访问性相关的想象力在今天的自由形状光学系统中也是明智的。结合传统和非传统光学应用，重点阐述了自由曲面光学发展和市场需求所需要的现代设计方法和制作技术。多年来，人们在自由曲面光学这一新兴领域进行了大量研究，但尚未建立公差和定义方面的标准。本文从成像和非成像两个方面对自由曲面光学系统的光学设计方法进行了综述。为了满足空间、天文、地球科学、国防、生物医学、材料加工、监视等各种应用的需求，已经开发了包括图形校正方法和计量学在内的多种减法制造技术来制造极端现代自由形状光学元件。我们描述了新型自由曲面光学元件的制造和计量方面的各种先进技术。接下来，我们还介绍了面向制造的先进光学设计方案。最后，我们对自由曲面光学设计、制造和计量的未来进行了展望。
Freeform optics has become the most prominent element of the optics industry. Advanced freeform optical designs supplementary to ultra-precision manufacturing and metrology techniques have upgraded the lifestyle, thinking, and observing power of existing humans. Imaginations related to space explorations, portability, accessibility have also witnessed sensible in today’s time with freeform optics. Present-day design methods and fabrications techniques applicable in the development of freeform optics and the market requirements are focussed and explained with the help of traditional and non-traditional optical applications. Over the years, significant research is performed in the emerging field of freeform optics, but no standards are established yet in terms of tolerances and definitions. We critically review the optical design methods for freeform optics considering the image forming and non-image forming applications. Numerous subtractive manufacturing technologies including figure correction methods and metrology have been developed to fabricate extreme modern freeform optics to satisfy the demands of various applications such as space, astronomy, earth science, defence, biomedical, material processing, surveillance, and many more. We described a variety of advanced technologies in manufacturing and metrology for novel freeform optics. Next, we also covered the manufacturing-oriented design scheme for advanced optics. We conclude this review with an outlook on the future of freeform optics design, manufacturing and metrology.
