title: Higher order aberrations in holographic lenses.
abstract: Third-, fifth-, and seventh-order aberrations have been analyzed for in-line and off-axis holographic lenses of different f/No. The seventh-order wave aberrations and the corresponding aberration coefficients are reported here for the first time. It has been concluded that when the holograms are to be used as optical elements, fifth- and seventh-order aberrations should also be considered along with the third order to achieve ideal imagery as both the chromatic and nonchromatic aberrations are quite large even when only small deviations from the recording geometry are present in the reconstruction step.
