Limitations to adaptive optics image quality in rodent eyes
Adaptive optics (AO) retinal image quality of rodent eyes is inferior to that of human eyes, despite the promise of greater numerical aperture. This paradox challenges several assumptions commonly made in AO imaging, assumptions which may be invalidated by the very high power and dioptric thickness of the rodent retina. We used optical modeling to compare the performance of rat and human eyes u...
متن کاملAdaptive optics performance model for optical interferometry.
The optical interferometry community has discussed the possibility of using adaptive optics (AO) on apertures much larger than the atmospheric coherence length in order to increase the sensitivity of an interferometer, although few quantitative models have been investigated. The aim of this paper is to develop an analytic model of an AO-equipped interferometer and to use it to quantify, in rela...
متن کاملGround Layer Adaptive Optics Performance in Antarctica
Ground layer Adaptive Optics (GLAO) is a new variant of adaptive optics that aims at correcting the seeing over a wide field of view by conjugating the deformable mirror to the boundary layer altitude.The South Pole is expected to be particularly to GLAO due to the absence of high altitude jets and the confinement of 96% of the seeing within a 220 m boundary layer. We present here the compariso...
متن کاملIntracavity adaptive optics. 2: Tilt correction performance.
This paper continues the discussion of the detailed experimental study conducted on adaptive optical control methodologies inside a laser resonator.(1) In this paper we discuss the experimental results for the correction of tilt within a laser resonator utilizing a multidither zonal COAT system. The tilt aberration was introduced in three different ways: (1) static tilt was introduced while the...
متن کاملPerformance of Hybrid Adaptive Optics Systems
Advances in Adaptive Optics (AO) systems and image processing techniques have allowed image reconstruction to reach new levels of sophistication with impressive improvements in resolvability. The products of these reconstruction methods are often compared by eye due to a lack of widely agreed-upon objective performance metrics. This presentation describes imagery of satellites taken with and wi...
