The purpose of this study was to examine the hypothesis that higher stimulus velocities could be tolerated in amblyopic and normal peripheral vision. The basis for this hypothesis is that a shift in the spatial scale of processing appears to account for the degradation in vernier acuity for moving stimuli in normal vision, and, to a large degree for the degradation in vernier acuity for station...

Superimposition of oriented grating masks on vernier targets results in bimodal patterns of vernier threshold elevation, with peaks occurring on either side of vernier target orientation. These bimodal masking effects suggest a contribution to vernier acuity from spatial filters tuned to orientations on either side of the target. We report similar bimodal threshold elevation with plaid masks co...

The eccentricity at which peripheral thresholds double their foveal value (E2) may relate to the visual system's anatomical organization. Using a variety of experimental approaches, previous estimates of E2 for vernier acuity have ranged from less than 0.1 deg to greater than 15.0 deg. This broad range of values seems to challenge the usefulness of E2 for determining visual topography. We expla...

Vernier acuity is a measure of the smallest horizontal offset between two vertical lines that can be behaviorally discriminated. To examine the link between the neuronal responses in a retinotopic mosaic and vernier acuity, we recorded the responses of single cells in cat lateral geniculate nucleus to a vertical bar stimulus that was stepped in small increments through the receptive fields of c...

In this paper, we study a wind energy conversion system designed for domestic use in urban or agricultural areas. We first present the turbine, which was specifically to be installed on buildings that it supplies. Based turbine characteristics, perform analytical sizing of Permanent Magnet Vernier Machine (PMVM), will used as generator our system. show influence operation by studying its associ...

Inter- and intra-observer variation in measuring the depth of invasion of malignant melanomas was assessed using three different techniques: eye-piece graticule, stage Vernier, and projection image analysis. Significant variation was found for all methods but was least pronounced with the stage Vernier. It is recommended that this should be the preferred technique for routine use.

We obtained (apparently) linear responses to luminance from three special displays of apparent motion, Vernier offset and stereoscopic depth. In our motion stimulus a dark and a light bar exchanged luminances repetitively on a grey surround. Motion was attributed to the bar that differed more from the surround, that is, on a dark surround the light bar appeared to jump, and on a light surround ...

Perceptual learning, a process in which training improves visual discrimination, is often specific to the trained retinal location, and this location specificity is frequently regarded as an indication of neural plasticity in the retinotopic visual cortex. However, our previous studies have shown that "double training" enables location-specific perceptual learning, such as Vernier learning, to ...

A modified-weak-value-amplification(MWVA) technique of measuring the mirror's velocity based on Vernier-effect has been proposed. We have demonstrated with sensitivity-enhanced and higher signal-to-noise ratio(${\rm SNR}$) by using two cascaded Michelson interferometers. These interferometers are composed similar optical structures. One interferometer a fixed mirror acts as part Vernier-scale, ...
