1 September 1991 Effect of coma correction on the imaging quality of holographic lenses

In studying the imaging quality of holographic lenses, many studies confine their scope to the examination of the third-order aberration theory and pay special attention to the possibility of coma correction. By a suitable choice of the recording geometry of the holo-lens it is possible to obtain aplanatic correction. However, the analysis of imaging quality based on numerical modeling of imaging which enables calculation of the aberration spot shape suggests that such correction does not necessarily give satisfactory results. Better imaging quality can be obtained for the other (nonaplanatic) holo-lens of the same spherical aberration and astigmatism, in spite of some non-zero coma. Further improvement can be achieved by slight compensation of coma obtained by curving of the holo-lens substrate and simultaneous correction of astigmatism following from the input pupil shift. The conclusions are confirmed by calculated aberration spots and incoherent transfer functions.
