用位相变换函数导出傍轴条件下透镜的物像距公式和横向放大率公式

The formulae of object-image distance and transverse magnifying rate are derived by phase transformation function of lens in the case of approximative axis

现代变换光学用空间频谱变换描述光学现象,而透镜等光学器件在光学系统中,起到位相变换作用。本文用透镜的位相变换函数导出了傍轴条件下透镜的物像距公式和横向放大率公式。

Modern transforming optics describes Optical phenomena using special frequency spectrum transformation,while lens and other optical devices have the function of phase transformation in optical systems.The formula of object-image distance and transverse magnifying rate are derived by phase transformation function of lens in the case of approximative axis.
