自由曲面光学构成了一项新技术，目前正在推动光束整形方面的重大变化。目前的大多数光束整形系统都是为固定的光学性质精心定制的，这意味着光束整形系统的输出光分布通常不能改变。这里我们介绍的是一类光束整形系统，其光学性质可以改变以满足不同应用的要求。所提出的光束整形系统由自由曲面透镜和非经典变焦系统组成，非经典变焦系统是利用光线瞄准和能量守恒来代替像差控制来设计的。自由形状透镜包括两个精心设计的自由形状光学表面，通过它们可以以所需的方式操纵入射光束的强度分布和波前。光束传播通过非经典变焦系统后，在固定的观察面上产生具有可变图案大小和在不同变焦位置的照度分布不变的照明图案。给出了两个设计实例，以验证所提出的波束整形系统的有效性。
Freeform optics constitutes a new technology that is currently driving substantial changes in beam shaping. Most of the current beam shaping systems are elaborately tailored for fixed optical properties, which means the output light distribution of a beam shaping system usually cannot be changed. What we present here is a class of beam shaping systems, the optical properties of which can be changed to meet the requirements for different applications. The proposed beam shaping system is composed of a freeform lens and a non-classical zoom system which is designed by ray aiming and the conservation of energy instead of aberration control. The freeform lens includes two elaborately designed freeform optical surfaces, by which both the intensity distribution and wave-front of an incident light beam are manipulated in a desired manner. The light beam after propagating through the non-classical zoom system produces an illumination pattern on a fixed observation plane with a variable pattern size and an unchanged irradiance distribution at different zoom positions. Two design examples are presented to demonstrate the effectiveness of the proposed beam shaping systems.
