Sentence examples for flickering illumination from inspiring English sources

However, following the flicker theory, the visual system would be structured to ensure small Δ C variation under flickering illumination.

Thus, although there might be a mechanism by which flicker-free visual signals would be generated under flickering illumination, the likelihood of such a possibility is low.

By sampling the light flicker across the spectrum, the broad sensitivity functions act to reduce the variation of cone output produced under wavelength-dependent flickering illumination.

To this end, we calculated the cone output (estimated by the quantum catch of cone pigments) when viewing an achromatic target (reflectance = 50% across the spectrum) under flickering illumination in a focal species, Metriaclima zebra (a Lake Malawi cichlid).

Output of opponent channels subjected to flickering illumination varied over time, showing variation largely comparable to that in the output of cones (SWS1-Rh2b, 0.059; SWS1-Rh2and0.059; and Rh2b-Rh2a, 0.013).

As in the computation of the spike-triggered average (Fig. 1c), the analysis is based on an experiment with flickering illumination and begins with collecting the stimulus segments that led to spikes, the spike-triggered stimulus ensemble.

It is called the critical flicker-fusion frequency, or CFF, and it is the lowest frequency at which a flickering light appears to be a constant source of illumination.

The effect is like looking at a flickering light bulb, and finding yourself unable to distinguish the darkness from the split seconds of illumination.

Retinal vessel diameters were measured for 4 min. For the second minute, full-field flickering light with a frequency of 12.5 Hz was used for stimulation by square wave pattern modulation of the fundus camera illumination at a contrast ratio of 25:1.

Photopic responses (background illumination intensity = 34 cd/m) were obtained with a wide-band filter (−3 dB at 1 Hz and 500 Hz) stimulating with single full-field flashes of white light (integrated luminance 3.93 cd.s/m), and cone responses were obtained with 30-Hz flickering white light (integrated luminance 0.81 cd.s/m) averaged from 20 sweeps.

The only other sources of illumination are flickering cathode-ray computer terminals, which make silhouettes of the heavily clad workers sitting at them.Down the corridor, in a huge office even colder than the main floor, the company's president sits at the head of a low table surrounded by friends.
