High accuracy is required in surface testing of 90nm nodal point lithography projecting lens. By comparing various aspheric surface testing methods  the structure layout of the compensator is a meniscus positive lens combined with a Plano-convex positive lens. The design results indicate that: primary and high order aberrations are balanced well  we adopt Offner null compensator to test the aspheric surface in the point diffraction interferometer at last. In this paper  MTF exceeds diffraction limit  an Offner compensator is presented on the base of the third order aberration theory to test concave aspheric surface  root-mean-square (RMS) of wave front error /167. The F-number of the system can achieve F/1.64. By the analysis of the process of aspheric surface testing with the designed system  the optical construction parameters of which is determined by introducing equal-quantities spherical aberration to compensate all orders of aspheric coefficients. The field of view of the system is 0.02  a loosen distribution of the tolerance was presented based on the accuracy of measuring apparatus. 2009 SPIE.

High speed photograph measuring instrument is mainly used to measure and track the exterior ballistics  which can measure the flying position of the missile in the initial phase and trajectory. A new high speed photograph measuring instrument is presented in this paper. High speed photography measuring system records the parameters of object real-time  and then acquires the flying position and trajectory data of the missile in the initial phase. The detection distance of high speed photography is more than 4.5km  and the least detection distance is 450m  under the condition of well-balanced angular velocity and angular acceleration  program pilot track error less than 5. This instrument also can measure and record the flying trail and trajectory parameters of plane  aero naval missile.
