Optical system design of simulator for autonomous landing on planets based on optical navigation
摘要
Abstract
In order to realize the simulation of autonomous landing on planets based on optical navigation and to satisfy the need of ground-based testing for system navigation algorithms, a scheme of simulator based on commercial projector′s projection system is suggested.The idea of optical system design are described espe-cially and the design results are given.First, the working principle and components of system are introduced. Then the optical specifications of projective lens and imaging lens are fixed based on the simulator′s technology demands, projector and CCD selected.Finally, the optical system layouts, aberration curves, spot diagrams and modulation transfer functions( MTF) are showed.Simulation results indicate that the symmetry of spot dia-grams is well to satisfy the demand of image processing and judgments, and the design value of MTF is close to 0.6 at the Nyquist frequency(91 lp/mm) and the imaging performance of system is good.The design results can be used for the following manufacture of simulator for autonomous landing on planets based on optical navigation.关键词
