Adaptive Optics Instrumentation

Frontiers in Optics 2009/Laser Science XXV/Fall 2009 OSA Optics & Photonics Technical Digest, 2009
Adaptive optics imaging of the retina presents unusual design challenges. AO instruments allowing steering of the beam across the retina, large amounts of defocus, and variable pupil sizes will be discussed.

Talker adaptation or “talker” adaptation? Musical instrument variability impedes pitch perception

Attention, Perception, & Psychophysics, 2022
When perceiving speech spoken by a single talker versus multiple talkers, listeners show perceptual benefits such as increased accuracy and/or decreased response time. There are several theoretical explanations for this talker adaptation phenomenon; one way to distinguish among these is to test whether adapting to stimulus structure is speech-specific ...

The MARTINI adaptive optics instrument

New Astronomy, 2000
Abstract The Multi-Aperture Real Time Image Normalisation Instrument (MARTINI) is an adaptive optics system designed to operate at one of the Nasmyth focal stations of the 4.2 m William Herschel Telescope. Correction of atmospherically distorted images is achieved by the action of a six element segmented mirror in a real-time servo loop controlled by

Instrumental variable adaptive array processing

IEEE Transactions on Aerospace and Electronic Systems, 1988
An instrumental variable (IV) approach is presented for estimating the weights of an adaptive antenna array. Theoretical analysis of the IV method shows that the antenna gain weights are independent of finitely correlated noise, so that unbiased estimation of signal arrival angles is possible.
