Design and analysis of thermal stability for main frame in Fizeau interferometer
An optical-structural-thermal model was built to analyze the thermal stability of an optical-structural system in the Fizeau interferometer. The analyzing process of the model
random distribution of environment temperatures
and the optical performance of the system were researched. Firstly
a random model for environment temperatures was built based on the thermal control system
and the thermal distribution and deformation of the optical-structural system were computed. Then
the surface forms and curvature radii of the optical component were fitted with the Zernike polynomial
and the fitted optical system was analyzed with the optical software. Finally
a random model to indicate the relationship of optical performance and temperature was built and the thermal stability of the main frame in the interferometer was discussed through analyzing the random model. Results indicate that the repeatability of the optical-structural system is 0.016% under believable level of 2 when the temperature is (220.1)℃
which satisfies the requirements of the Fizeau interferometer for stability.
