Cylindrical wavefront
http://wyant.optics.arizona.edu/zernikes/Zernikes.pdf 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.

WebA wavefront aberration is defined as the deviation of the wavefront that originates from the measured optical system from reference wavefront that comes from an ideal optic system. The unit for wavefront aberrations is microns or fractions of wavelengths and is expressed as the root mean square or RMS. The purpose of wavefront analyses of the ... Webthe wavefront variance can be calculated in a simple form by using the orthogonality relations of the Zernike polynomials. The final result for the entire unit circle is (63) Table VI gives the relationship between σ and mean wavefront aberration for the third-order aberrations of a circular pupil. While Eq.
Web2. Cylindrical wavefront. When the source of light is linear in shape, such as a fine rectangular slit, the 9.3 wavefront is cylindrical in shape. This is because the locus of all such points which are equidistant from the linear source will be a cylinder [Fig. 9.1(b)] of 3. Plane wavefront. As a spherical or cylindrical tr dels
