Adaptive optics implementation with a Fourier reconstructor.
Adaptive optics takes its servo feedback error cue from a wavefront sensor. The common Hartmann-Shack spot grid that represents the wavefront slopes is usually analyzed by finding the spot centroids. In a novel application, we used the Fourier decomposition of a spot pattern to find deviations from grid regularity. This decomposition was performed either in the Fourier domain or in the image do...
متن کاملA Computationally EÆcient Wavefront Reconstructor for Simulations of Multi-Conjugate Adaptive Optics on Giant Telescopes
Multi-conjugate adaptive optical (MCAO) systems with from 10 to 10 degrees of freedom have been proposed for future giant telescopes. Using standard matrix methods to compute, optimize, and implement wavefront reconstruction algorithms for these systems is impractical, since the number of calculations required to compute (apply) the reconstruction matrix scales as the cube (square) of the numbe...
متن کاملDesign aspects of the reconstructor for the Gemini Adaptive Optics System (Altair)
The Gemini Telescopes Project is a collaboration to develop two leading edge 8 metre telescopes; Gemini North on Mauna Kea, Hawaii, and Gemini South at Cerro Pachon, Chile. These telescopes will exploit the excellent natural seeing conditions of the sites for observations in the visible and near infrared. To capitalise on the excellent natural image quality that these telescopes will provide, a...
متن کاملImplementation of quantum search algorithm using classical Fourier optics.
We report on an experiment on Grover's quantum search algorithm showing that classical waves can search a N-item database as efficiently as quantum mechanics can. The transverse beam profile of a short laser pulse is processed iteratively as the pulse bounces back and forth between two mirrors. We directly observe the sought item being found in approximately square root[N] iterations, in the fo...
متن کاملFourier transform digital holographic adaptive optics imaging system.
A Fourier transform digital holographic adaptive optics imaging system and its basic principles are proposed. The CCD is put at the exact Fourier transform plane of the pupil of the eye lens. The spherical curvature introduced by the optics except the eye lens itself is eliminated. The CCD is also at image plane of the target. The point-spread function of the system is directly recorded, making...
