Behavioral measurements of visual processing in adult male and female hooded rats: Do visual tasks reflect sex differences in visual cortex morphology?
… Three types of visual functions--grating acuity, vernier acuity, and motion parallax information--that are processed in the primary visual cortex were examined. Grating acuity was measured in a forced choice Y-maze and a jumping stand. Using a criterion of 34 correct/50 trials, grating acuity for …

The Dark Focus of Visual Accommodation: Its Existence, Its Effects, Its Measurement
… Experiment I, a new optometer -- the polarized vernier optometer -- is described and compared experimentally to the better-known laser optometer. The former compared favorably to the latter in terms of subject acceptability and agreement of dark focus measurements.

Design of a fluidic test bed for MEMS piezoelectric energy harvester
… and designing it around dimensional analysis, a Vernier Low-g accelerometer is used to measure the vibration spectrum. The frequency that was analyzed was 251.01 ± 0.447 Hz and when converted back to the Alaskan pipeline we achieved a frequency of 6.94Hz. Using this information we can design PMPG …

Perception and Eye Alignment Control: Do People Think the Same Way Their Brain Thinks?
… contrast. A similar effect occurs for motion and vernier thresholds when the target components being compared have different contrast. The effect occurs especially for middle and low spatial frequencies. This study compares observers’ stereoscopic depth perception with vertical disparity vergence …
