Quantitative analysis and experiment of Foucault knife-edge test
In this paper the problem of quantitative analysis of the knif-edge test is studied. Taking the Linfoot s integral function as theoretical base, two methods for finding out the error function are derived. As an example, a precision spherical mirror is experimentally tested and the error curve is calculated. The amount of imperfection of the mirror is found to be 0.046λ, that is very close to the estimated value by the optician who makes it.
