Abstract
The location of the focal surfaces for parabolic cylinder reflectors with Gaussian tapered illumination is investigated and compared with that obtained by numerical simulation. It is found that an idealized surface that holds approximately in most practical cases is the circle described on the vertex-focus line as diameter. Formulas are derived for the change of gain and beamwidth with scan angle.
