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.

It is difficult to get high compression ratio and good reconstructed image by conventional methods  we give a new method of compression on medical image. It is to decompose and reconstruct the medical image by wavelet packet. Before the construction the image  use neural network in place of other coding method to code the coefficients in the wavelet packet domain. By using the Kohonen's neural network algorithm  not only for its vector quantization feature  but also for its topological property. This property allows an increase of about 80% for the compression rate. Compared to the JPEG standard  this compression scheme shows better performances (in terms of PSNR) for compression rates higher than 30. This method can get big compression ratio and perfect PSNR. Results show that the image can be compressed greatly and the original image can be recovered well. In addition  the approach can be realized easily by hardware.
