理想光学系统

在实际工作中光学系统会出现多种像差，所以对激光光束经过非理想光学系统的聚焦特性研究具有实际意义。

In practice there will be a variety of aberrations , so the investigation of focusing properties of the laser beams passing through an non-ideal optical system has practical interest .

根据望远镜的工作原理，对变焦距光学镜头的变焦运动进行了定性分析，并且根据理想光学系统的物像关系式推导出该镜头运动镜组的运动方程。

The zooming movement of zoom optical lens is qualitatively analyzed according to operating principle of telescope . The movement equation for the lens moving lens set is derived according to the object-image relationship of the ideal optical system .

现有对光学系统成像的仿真可分为两类，一类是采用理想光学系统模型仿真出对物体所成的像，未考虑光学系统的实际参数、像差和加工、装配误差。

The existing simulation method for optical system can be divided into two categories . One is using ideal optical system model to simulate image the object formed , but the actual parameters , aberration , processing and assembly of the optical system cannot be considered .

理想的光学系统是不受物理条件约束的，每个物点都成理想点像。

Perfect optical system dose not be inhibited by physical conditions and every object point has ideal point image .

理想的HMD光学系统应该重量轻、体积小。

A perfect HMD optical system should be light weight and compact .

为了获得一个较理想的物镜或光学系统，从光学设计理论和实践角度来说，设计结果体现使用要求的成象质量评价问题极为重要。

In order to obtain a high quality objective or optical system , it is of vital importance in theory and practice of the optical design that the designing results should satisfy the evaluation of the image quality accorded with the use requirements .
