In order to measure high accuracy or mid spatial frequency optical surfaces
this study investigated imaging system in Fizeau interferometer. Interferometer is a transferring phase information system. General transfer function can't evaluate the ability of imaging system in interferometer that transfers the phase information of the optical surface. So this paper deduced instrument transfer function (ITF) and used ITF to evaluate the phase information transfer ability of interferometer. We obtained some results about ITF of imaging system by numerical simulation when there are different aberrations in imaging system or measuring optical surfaces were different. Our results indicate that ITF can evaluate the ability of transferring phase information in interferometer and the distortion of imaging system evidently affects the accuracy of interferometric measurements. 2010 IEEE.

We calculate the influence of temperature change on the refractive index of air
establish a model of air temperature distribution and analyze the effect of different temperature distribution on the high accuracy interferometric metrology. First
a revised Edlen formula is employed to acquire the relation between temperature and refractive index of air
followed by introducing the fixed temperature gradient distribution among the spatial grid within the optical cavity between the reference flat and the test flat of the Fizeau interferometer
accompanied by a temperature change random function within each grid. Finally
all the rays through the air layer with different incident angles are traced by Matlab program in order to obtain the final output position
angle and OPD for each ray. The influence of different temperature distribution and the length of the optical cavity in on the testing accuracy can be analyzed through the RMS value that results from repeatable rays tracing. As a result
the horizontal distribution (vertical to optical axis) has a large effect on the testing accuracy. Thus
to realize the high accuracy figure metrology
the horizontal distribution of temperature must be rigorously controlled as well as to shorten the length of the optical cavity to a large extent. The results from our simulation are of great significant for the accuracy analysis of interferometric testing and the research of manufacturing a interferometer. 2010 Copyright SPIE - The International Society for Optical Engineering.
