ECE523 Solutions to Homework 1 1. O.P.L.= nd is the product of the geometric length of the path light follows through the system and the index of refraction of the medium through which it propagates. 2. Wavefront The wavefronts are the surfaces of equal phase. 3. Paraxial Optical components are often centered about an optical axis, about which the rays travel at small inclinations. Such rays are called paraxial rays. This assumption is the basis of paraxial optics. 4. aspherical lens An aspheric lens or asphere is a lens whose surfaces have a profile that is rotationally symmetric, but is not a portion of a sphere.[1] In photography, a lens assembly that includes an aspheric element is often called an aspherical lens. 5.Numerical Aperture NA is known as the numerical aperture of the fiber. 6. Eikonal The ray trajectories are often characterized by the surfaces to which they are normal. Let S(r) be a scalar function such that its equilevel surfaces, S(r) = constant, are everywhere normal to the
