We use cubic-phase plate imaging to demonstrate an order-of-magnitude impro
vement in the transverse resolution of three-dimensional objects reconstruc
ted by extended depth-of-field tomography. Our algorithm compensates for th
e range shear of the cubic-phase approach and uses camera rotation to cente
r the reconstructed volume on a target object point. (C) 1999 Optical Socie
