We discuss an asymptotic method for computing the intensity of the light field produced by a diffractive optical element (DOE) to focus into an arbitrary line using the curvilinear coordinates. The structure of the light field produced by the DOE intended to focus into a linesegment is studied. A comparison is drawn between the results of the asymptotic and numerical methods of computation.
