Decomposition of the optical transfer function: wavefront coding imaging systems.
We describe the mapping of the optical transfer function (OTF) of an incoherent imaging system into a geometrical representation. We show that for defocused traditional and wavefront-coded systems the OTF can be represented as a generalized Cornu spiral. This representation provides a physical insight into the way in which wavefront coding can increase the depth of field of an imaging system an...
متن کاملTheory and Application of Differential OTF (dOTF) Wavefront Sensing
A new image-based technique for measuring the complex field in the pupil of a telescope is presented. The simplest form of the method uses two point source images, one with a small modification introduced in the pupil. The processing of the images is very simple and non-iterative. The method is based on a specially-defined complex functional derivative of the OTF. This derivative is approximate...
متن کاملExperimental Evaluation of Differential OTF (dOTF) Wavefront Sensing
Differential Optical Transfer Function (dOTF) is an image-based non-iterative technique for measuring the complex pupil field. The technique relies on the difference between two PSF images when a small modification is introduced near the pupil’s edge. The nature of the modification is of minor importance and can consist of a transmission blockage or a phase shift introduced by poking a single D...

متن کاملWavefront sensing for WFIRST with a linear optical model
In this paper we develop methods to use a linear optical model to capture the field dependence of wavefront aberrations in a nonlinear optimization-based phase retrieval algorithm for image-based wavefront sensing. The linear optical model is generated from a ray trace model of the system and allows the system state to be described in terms of mechanical alignment parameters rather than wavefro...
