Wide field diffractive lenses for imaging, scanning, and Fourier transformation
Diffractive optical elements offer the potential to reduce significantly the weight, size, and cost of a variety of optical systems that currently use refractive and/or reflective components. Unfortunately, the utility of conventional holographic lenses has been plagued by uncorrected field aberrations, particularly coma and astigmatism. However, recent advances in surface-relief diffractive lenses provide the optical designer with enough degrees of freedom to eliminate third-order coma, astigmatism, and field curvature.
