Abstract

Artal and co-researchers are primarily credited with formulating the principle of the double-pass method for obtaining the ocular point spread function (PSF) in 1998. This method requires a long time to calculate the partial phase-retrieval algorithm based on the iteration method. The purpose of this study was to develop a new and rapid phase retrieval algorithm. We developed a new algorithm that extrapolates the value of the real and imaginary parts of the optical transfer function (OTF). This algorithm was obtained from the characteristics of the continuous changes of the OTF value. In this article, we describe the new algorithm and its effectiveness by simulating and reconstructing ocular PSFs using double-pass PSFs with the same and different pupil sizes.
