Tunable focalizers as nonconventional phase filters
Cristina M Gómez-Sarabia1, Ángel Sauceda-Carvajal2 and Jorge Ojeda-Castañeda3


We disclose the use of tunable focusing elements as phase-only spatial filters for designing nonconventional optical systems. We revisit the use of a pair of masks with helically phase variations implementing a spherical varifocal lens. This result is extended to the design of another pair of phase masks that can control astigmatism. © Anita Publications. All rights reserved.
