查询词典 simulation

The simulation result shows the collection efficiency of TIR lens model is 67% when the angle of light is confined within 15°. And the uniformity on observation screen is improved in some degree. The optimal design of TIR lens further provides the development space of LED micro-projection display system.4 On the base of the theory research and the model simulation, four projection display systems which have LCOS as micro-display panel and which combine different optical devise for UHP and LED light source respectively are proposed in this dissertation. And the quality of projection display system is evaluated by thesimulation outcome.
