We describe and analyze an optical device capable of generating tilt, defocus, astigmatism, coma, and spherical aberration wave-front deformation. This optical device consists of a pair of aspheric plates that produce aberrations by laterally shifting one plate relative to the other. The surface descriptions of these optical plates are provided, and their aberration-inducing properties are verified with ray-tracing software. In addition, we examine the versatility and the limitations of using variable aberration generators and provide insight into how aberrations may be controlled by a simple lateral shift. The device may find application in aberration control in lens systems that are nonrotationally symmetric.
我们描述并分析了一种能够产生倾斜、散焦、像散、彗差和球差波前变形的光学装置。该光学装置由一对非球面平板组成，通过使一个平板相对于另一个平板横向移动来产生像差。提供了这些光学平板的表面描述，并使用光线追迹软件验证了它们的像差诱导特性。此外，我们研究了使用可变像差发生器的通用性和局限性，并深入了解如何通过简单的横向移动来控制像差。该装置可应用于非旋转对称的透镜系统中的像差控制。
