His voice grates on me.
Schematic diagram of the effect of off-axis grating orientation on the frequency of intersections of the grating with a thin-line process.
Movements of the eyes bring about changes in the relative phases of a par ticular grating on different trials.
If the two gratings are in phase, the resulting combination is a stronger stimulus than either grating alone.
Right-end plots display the initial changes in horizontal and ver tical positions, as a function of grating and line-endings speeds, respectively.
Change in ver tical position increased monotonically with grating speeds up to 50 deg 0s, in both control and "barber pole" conditions.
The effects of grating area and spatial frequency on contrast sensitivity as a function of light level.
After reflecting off the grating the resulting fringe pattern or ' spectrogram ' may be viewed or photographed at the exit port of the spectrometer.
Large-aperture compression gratings require stringent compression grating alignment to minimize beam shear, pedestal, and pulse lengthening effects.
