Abstract
A method is developed for analytically determining the holographic optical element phase transfer function. The method is based on the minimization of the weighted mean-squared wave-front aberration. It is shown that the wave-front aberration can be described as the linear function for unknown aspheric wave phase correction coefficients. Thus this method does not require many convergence calculations, and the optimal aspheric phase transfer function is obtained analytically. This method is applied to a holographic straight-line scanner design, and the optimal solution is obtained.
