Lens Design by Statistical Analysis

Berlyn Brixner

A new method of lens designing, based on the statistical analysis of traced geometrical skew rays as a function of lens-parameter changes, is both faster and more precise than traditional methods using the Seidel simplified approximate analytic functions devised originally for hand computation. The great speed with which the electronic computer can process large masses of numerical data makes the new method practical. The least-squares technique makes it possible to handle a problem which would otherwise be unmanageably large. The technique is especially versatile when the complexity of problems to be solved varies over a great range. Through the sequence of tracing rays to obtain data, evaluating image errors from the data and minimizing these errors by iteration, it reduces lens designing to a curve-fitting system.
