Otherwise the distortion of reconstructing image emerges,and it came from the wave aberration.

After the interferograms pickuped in the experiment are digialized, they are processed bya computer and fit with Zernike polynomial the wave aberration, peak-valley err6r, root-mean-squareerror and various geometric aberrations can be obtained for various sampling points.

Fifth order wave aberrations of rotationally symmetric electron optic system are studied in detail.

Extreme ultraviolet lithography(EUVL) technique is one of the most promising candidate next-Generation lithography technologies,in order to achieve diffraction-limited performance,the allowable wavefront error of the optical system must be less than one fourteenth of its work wavelength,viz.

To analyze the effect, finite element analysis software ANSYS is adopted to simulate a 400 mm plano-convex lens from a collimator, and a method is presented to analyse wavefront error caused by axial deformation of lens, P-V and RMS values of axial deformations under gravity are computed in different cases, the contours of lens surface are plot.

Based on the theory of optical wavefront error and combining the engineering practice, the thermal optical evaluation has been done to the optical window with non symmetric temperature field.

Error-separation model for interferometric testing aspheric surfaces based on wavefront aberrations;

With the primary aberration theory and relationship between the optical recording system and the diffraction wavefront aberration of the grating,it is concluded tha.

In the design of cubic phase plate testing system by taking Computer Generated Hologram(CGH) as a null lens,two very important principles are the wavefront aberration of cubic phase in propagation and the separation of diffraction orders.

Based on Chrisp’s wave-front aberration theory of grating, the wave-front aberration coefficients are derived with a grating surface of polynomial expression, which can be used to design and analyze a grating of toroidal or conicoid surface figure.
