Peripheral detection acuity for interference fringes and screen-based Gabor gratings
Free-to-read version at publisher website
Description
This study compared on-axis and peripheral detection acuities measured with interference fringes, that bypass eye optics, and with screen-based Gabor gratings combined with an adaptive optics system. Gabor gratings are sinusoidal gratings incorporated with a Gaussian envelope that attenuate spatial frequency broadening that occur at the window edge. The magnitude of the attenuation was varied. Peripheral detection acuities were always higher for interference fringes than for Gabor gratings. Less attenuated Gabors (with sharper edges) had higher acuities than more attenuated Gabors (with less sharp edges). Theoretical investigations indicated that the spatial frequency broadening occurring due to the sharp edge of the less attenuated Gabors contribute little to high detection grating acuity in the periphery, but that the lower attenuation provides a greater number of visible cycles which is of more benefit to detection than is the case on-axis.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
