Cylindrical wavefront

WebA CGH can generate a cylindrical wavefront to match the curvature of the test surface. Similar to testing a sphere with a Transmission Sphere, a single cylinder CGH allows for testing a wide range of cylinder optics. … WebA wavefront is always normal to the light rays, and it never propagates backwards. Wavefronts can be one of three sorts, depending on the shape of the light source. Spherical wavefront The wavefronts of light that emerge from a point source are spherical. Cylindrical wavefront. The wavefronts are cylindrical when the light source is linear.
