Abstract

The intensity and encircled energy functions of an image formed by a diffraction-limited optical system with a strut supported centrally obscured circular pupil are derived and evaluated. Results presented give quantitative information on the reduction in energy in a focal plane area due to the presence of struts as a function of central and strut obscuration geometry.

摘要

推导并评估了由带有支柱支撑的中心遮挡圆形光瞳的衍射极限光学系统所形成图像的强度和环围能量函数。给出的结果提供了关于由于支柱的存在而导致焦平面区域能量减少的定量信息，该信息是作为中心遮挡和支柱遮挡几何形状的函数。
