PROJECTION SYSTEM AND METHOD WITH MODULAR PROJECTION LENS

A projection lens system and a method thereof relate to: a Fourier lens assembly comprising a first attachment segment, the Fourier lens assembly configured to form a Fourier transform of an object at an exit pupil of the Fourier lens assembly; an aperture configured to block 5 a portion of the incident light, the aperture substantially located at the plane of the Fourier transform; and a zoom lens assembly, the zoom lens assembly including a second attachment section, the second attachment section configured to be removably attached to the first attachment section. 一种投影透镜系统及其方法涉及：傅里叶透镜组件，该傅里叶透镜组件包括第一附接段，傅里叶透镜组件被配置为在该傅里叶透镜组件的出射光瞳处形成物体的傅里叶变换；光圈，该光圈被配置为阻挡5入射光的一部分，该光圈大致位于傅里叶变换的平面处；以及变焦透镜组件，该变焦透镜组件包括第二附接段，该第二附接段被配置为可移除地附接到第一附接段。
