Line-spread function relatively insensitive to defocus.
A new approach for obtaining line-spread functions (LSF's), which vary slowly in out-of-focus planes, is described. Based on this approach, we report a LSF that shows relatively less sensitivity to focus errors than that shown by both the diffraction-limited LSF and a LSF previously reported.
