Optical Wavefronts and Their Aberrations
2013The position and the size of the Gaussian image of an object formed by an optical imaging system is determined by using its Gaussian imaging equations. We have stated in Chapter 1 that the quality of the diffraction image depends on the aberrations of the system. A spherical wave originating at a point object is incident on the system. The image formed

A discussion of two wavefront aberration correction procedures
Ultrasonic Imaging, 1992This review paper discusses the basic properties of two adaptive signal processing procedures for dealing with weak scattering in a phased array transducer system. A fundamental improvement in the lateral resolution of ultrasonic echo scanners will result if the weight vector of a large phased array transducer can be modified to account for distortion

Polynomial expansion of heavily aberrated wavefronts
Annual Meeting Optical Society of America, 1986A wavefront expansion with the aid of Zernike polynomials is effective for predicting the quality of optical systems close to the diffraction limit.
