Analog Holographic Wavefront Sensor for Defocus and Spherical Aberration Measurement Recorded in a Photopolymer

Autor: Emma Branigan, Suzanne Martin, Matthew Sheehan, Kevin Murphy

Publikováno v: Articles

An analog holographic wavefront sensor (AHWFS), for measurement of low and high order (defocus and spherical aberration) aberration modes has been developed as volume phase holograms in a photopolymer recording medium. This is the first time that hig

Direct multiplexing of low order aberration modes in a photopolymer-based holographic element for analog holographic wavefront sensing

Autor: Matthew Sheehan, Emma Branigan, Suzanne Martin, Kevin R. Murphy

Publikováno v: Conference Papers

The fabrication of an analog holographic wavefront sensor, capable of detecting the low order defocus aberration, was achieved in an acrylamide-based photopolymer. While other implementations of holographic wavefront sensors have been carried out dig

Wavefront tomography of the human eye assisted with corneal topography and optical path measurements

Autor: Maciej Nowakowski, Matthew Sheehan, Alexander V. Goncharov

Publikováno v: Frontiers in Optics 2011/Laser Science XXVII.

We present a new method of reconstructing the optical system of the human eye based on combined measurements from an aberrometer and corneal topographer (iDesign, Abott Medical Optics) and a partial coherence interferometer (IOL Master, Zeiss). The c
