The distortion made by optical lens largely affect the measurement accuracy of the large field of view photoelectricity measurement system
according to the theory of aberration in the photoelectricity system
this paper design a series of distortion measurement devices
in connection with the process of distortion correction in photoelectricity system
establish the related mathmatics model
make the real time distortion correction by the method of software compensation. The experimental results demonstrate the method decrease the measurement error made by the photoelectricity system distortion
after the compensation
in tatal field of view
the systematic measurement error is less than 0.5 picture element. 2010 IEEE.

A design method of aspherical surface for panoramic imaging system with two mirrors using multi-populations genetic algorithms is proposed. Astigmatism induced by mirrors may significantly compromise image resolution. To solve this problem
we induced algebraic expression of astigmatism in panoramic imager based on generalized Coddington equation and theory of geometric optics. Then
we propose an optimization process for mirror profile design to eliminate astigmatism and provide purposely-designed projection formula with aid of MPGA. A series of polynomial expressions of aspherical surfaces are obtained and procedures of the design are presented. In order to facilitate ray tracing and aberration calculation
even asphere surface model is obtained by using of hybrid schemes combining MPGA and damped least squares. Finally
a prototype of the catadioptric panoramic imager has been developed and panoramic ring image is obtained. 2009 SPIE.

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.

The results of design effort for infrared zoom systems using all reflective aspheric surfaces are described. Issues such as the paraxial design theory and aberration balancing are discussed in detail. Two all reflective zoom optical systems are disclosed clearly. Both of them are to be used with uncooled infrared detectors. The first design is an unobscured three mirror zoom system without any intermediate image
and the second is a three mirror system with central obscuration which forms an intermediate image. With the design theory further developed
this kind of systems can be designed for cooled infrared detectors
for which cold stop matching is an important issue. 2006 SPIE-OSA.
