WebThe beam parameter product (BPP) is another metric used to evaluate the quality of a laser beam. It is defined as the product of the beam radius at the beam waist and the half-angle … WebTypically, the wavefront map is described by Zernike polynomials, a set of orthogonal polynomials that arise in the expansion of a wavefront function for optical systems with circular pupils, such as eyes. An arbitrary wavefront profile can be expressed by the sum of individual Zernike terms, multiplied by coefficients known as Zernike ...
