Abstract


This paper first introduces the history and current situation of the development of the the secondary curved mirror Lucky Inspection Act the Lucky inspection of geometric and physical principles , followed Ronchi grating production principles and traditional the Lucky testing the sensitivity of analytical methods and definitions theory. Sensitivity for the secondary curved mirror Lucky inspection method , the analysis of a new assessment method , its physical significance of the mirror the deviations size capacity a Lucky grating period can be detected . I.e. if a given grating able to detect the slope of the mirror deviation is smaller, its detection capacity is greater , the detection sensitivity is greater . This assessment method research grating period the size of the mirror deviation based Lucky inspection geometric principles and use ray tracing method sensitivity formulas derived Lucky inspection to identify the the constraints test sensitivity factors and parameters . Then numerical data , combined with the design parameters for the parabolic mirror , hyperbolic mirror and ellipsoid mirror . Came to the conclusion the curve Lucky interval test sensitivity , respectively, with the grating period , half through the aperture larger decreases general law . On this basis , the paper also Lucky accuracy testing to do further research , the aim of the quantitative analysis of a Lucky specific parameters that can be detected by the grating period mirror the size of the error value . Similarly , for secondary curved mirror test the accuracy of numerical analysis and concluded that further validate the correctness and reliability of the new method defined test sensitivity . This article also prepared can run out of Matlab environment Lucky testing the sensitivity and accuracy of the calculation and curve drawing software . Lucky inspection sensitivity is defined detailed study and restrict the impact of the parameters on test sensitivity secondary curved mirror test for future application Lucky testing methods , including a follow-up inspection of large diameter aspherical lens provides the theoretical basis of the test sensitivity , has a very important academic value and significance .
