چکیده انگلیسی
In this paper, we present a novel method for testing the long focal length lens of large aperture, which is realized by calculating the angle of moiré fringe formed by Talbot image of two Ronchi gratings. A scanning method was developed to measure the focal length with the collimated lights projected on the different aperture position of the lens. Experiment data demonstrates that this method can be applied to the real-time long focal length measurement with high accuracy.
