Abstract :
In the present paper modified Fizeau interferometer is discussed. The interferometer allows to diagnose plane and spherical optical elements with diameter of 10-300 mm. Accuracy of the measurements is lambda/10 (lambda=0.63 m). A new method of interference patterns reconstruction based on reference lines is proposed. This method allows to increase the reliability of interferometric pattern reconstruction and suppress the influence of incoming noise.
