What is Ray and Wavefront Aberrations Analysis about?

This document discusses various optical aberrations that cause ideal imaging systems to have imperfect focus. It defines ray and wavefront aberrations and explains how they are mathematically related. Specific aberrations covered include spherical aberration, coma, astigmatism, field curvature/Petzval curvature, and distortion. For each aberration, the document provides the ray intercept polynomial terms, ray plots, and wavefront plots to illustrate the aberration. It also discusses how aberrations combine
