Lens Detection Technology and its Machining Allowance Prediction Based on MATLAB

Article Preview

Abstract:

The detection of lens’ surface smoothness is an important technical problem in the production practice. Through analysis the recognition characteristics of lens, the Newton Ring interference fringe of planoconvex lens is simulated by MATLAB first. Stripe brightness curve is analysis based on improfile function method, and the brightness standard curve of ideal lens system is established. Through comparison the brightness curve produced by Newton Ring of standard lens and the sample, the flatness of the lens surface and defect depth or bump height are assessed. This method is easy to application and has higher adaptability to environment. It provides a new method for the detection of lens’ surface smoothness.
