This package provides the functions to correct quadratic phase aberration.

To install this package, open the Julia REPL and run

julia> ]add QuadraticAberrationCorrector

or

julia> using Pkg
julia> Pkg.add("QuadraticAberrationCorrector")

Import the package first.

julia> using QuadraticAberrationCorrector

When the following code is executed, the phase ϕ is corrected by the least squares algorithm and stored in ψ.

julia> ψ = CorrectAberration(ϕ)

When using the weighted least square algorithm, use the following function.

julia> ψ = WeightedCorrectAberration(ϕ, 10, 10)

For more information on the algorithm, please refer to the following reference.
