This Fourier lens system is often used in optical signal processing system. Based on the design principles of Fourier lens system and the requirements of some particles observation experiment
a Fourier optical system whose working wavelength was 532nm was designed using ZEMAX. The testing experiment using the visual microscope
showed that the system's resolution was 250lp/mm. And the system was successfully used in the particles observation experiment. 2011 IEEE.

Computer-generated holograms (CGH) have been widely used for years in optical testing of aspheric surfaces in combination with Fizeau interferometers. With the development of diffraction optics
computer technology
and micro-processing technology
the accuracy of the CGH testing can achieve a hundredth of a wave
and the cost is reduced greatly. CGH is capable of producing an optical wavefront with any desired shape. So it is fascinating and will have good prospects to test free-form surfaces using CGH. As the CGH can create any wavefront shape
it can also be used in unsymmetrical aspherical surfaces testing. Taking the cubic surface as an example
this paper gives a method to test unsymmetrical surfaces. This paper gives the design to test a cubic surface. And the separation of the diffraction orders and the binary process of the continuous CGH phase function are discussed in detail. The alignment tolerance of the test system and the CGH fabrication tolerance are analyzed. We also present an idea using a CGH and two spherical lenses as null lens to test the cubic surface when the surface deviation is great. 2011 IEEE.

In high precise surface testing
temperature stability and uniformity are of paramount importance to the high accuracy of test results. Micro-temperature variation and temperature gradients not only cause the change of the air refractive index and lead to the optical path variation in interferometer cavity
but also result in deformation of the tested surface itself
which always brings about errors to the test results. Temperature effects on the interferometer cavity and the tested surface are analyzed from the axial and radial directions in this letter. Temperature model of the interferometer cavity and the tested lens are established and quantitative calculations and diagram of test results versus temperature and lens dimension are provided. It shows that temperature gradients effect increase with the length of the interferometer and the dimension of the tested lens. The interferometer cavity is mainly affected by radial temperature gradients while the tested lens is mainly affected by the axial temperature gradients. 2010 Copyright SPIE - The International Society for Optical Engineering.

Computer-generated hologram (CGH) is an effective way to compensate wavefront in null test of aspheric surfaces and freeform surfaces. Our strategies of CGH design and fabrication for optical testing are presented
and an experiment demonstrating the compensation results of CGH and null lens is also reported. In order to design complex CGH
software was developed
with which we can design a CGH including three sections: main section for compensating wavefront in null test
alignment section for adjusting the relative position between CGH and interferometer
and fiducial section for projecting fiducial marks around the optics under test. The design result is represented in GDS II format file which could drive a laser-direct-writer- machine to fabricate a photomask. Then
a 1:1 replication process is applied to duplicate the patterns from photomask to a parallel optical substrate whose surface is error better than /60 rms. Finally
an off-axis aspheric surface was tested with CGH and null lens respectively. The test result with CGH (0.019rms) is almost the same as the result with null lens (0.020 rms). This experiment also demonstrated that fiducial marks projected by CGH can be used to guide the alignment of the optics and measurement of its off-axis distance. 2010 Copyright SPIE - The International Society for Optical Engineering.

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.
