Abstract
3-D images obtained from optical sectioning microscopy are usually degraded by a point-spread function that is known to be an even function but is otherwise only approximately known, or even entirely unknown. We present a new algorithm for 3-D blind deconvolution of even point-spread functions that is both fast and (in the absence of noise) exact. Fourier transforms decouple the problem into 2-D, then 1-D blind deconvolution problems, greatly increasing computational speed. Numerical simulations demonstrate that the blind algorithm seems to perform both faster and more accurately than the non-blind iterative Lucy-Richardson algorithm.
