Fixed gaussian distance
Web摘要： We develop formulas for Gaussian beam transformation with fixed total distance between beamwaists, and consider the use of cylindrical lenses or mirrors to produce beams which are not symmetric about the axis of propagation. WebThe distance is usually Euclidean distance, although other metrics are sometimes used. They are often used as a collection {} which forms a basis for some function space of …

There are three unknown parameters for a 1D Gaussian function (a, b, c) and five for a 2D Gaussian function (;,;,). The most common method for estimating the Gaussian parameters is to take the logarithm of the data and fit a parabola to the resulting data set.
