基于曲面拟合的光学偏折系统显示屏标定方法
Calibration Method for Optical Deflection System Display Screen Based on Surface Fitting
摘要
Abstract
A surface fitting method is proposed to fit the surface shape distribution of the display screen,which is the most critical calibration step in the transmission optical deflection system.A wavefront detection simulation model based on transmission optical deflection technique is established,and the impact of two different display screen surface fitting methods on wavefront measurement is analyzed.The simulation results show that the root mean square error(RMS)of the wavefront aberration of the planar screen model is 0.837 5 μm.The RMS value of the simulated wavefront aberration of the curved screen model is only 0.059 6 μm.Using a transmissive optical deflection system for wavefront measurement of spherical lenses,the RMS value of wavefront aberration in the curved screen model is 0.137 1 μm.The RMS value of wavefront aberration in the flat screen model is 1.432 6 μm.The experimental results show that the use of surface fitting is significantly better than plane fitting,confirming the feasibility of surface fitting screen models.关键词
