Let us denote the ratio of brightness at the center of the image to that at the edge by r = I 0,0)/ I 0, π/2).
Grouping all the coincident events detected in all the experiments, the average ratio of brightness in the blue and the red channel obtained was 0.906.
It is well-known in astrophysics that the ratio of brightness at the center of the disc of a star to that at the edge is equal to 2.9 [ 22].
Each display offers a 2000:1 dynamic contrast ratio, 300 nits of brightness, and 5ms response time.
As the labeled fibrils seem to have a ratio between blue and red labeled monomers of 2.3, we also checked if there is a size-dependence of the ratio between brightness of oligomers detected in our experiments.
Other specs include a contrast ratio of 4,000 1, 450cd/m2 brightness, 178° viewing angle and a 5.5ms response time.
The TVs also boast a contrast ratio of 15,000 1, a brightness of 450cd/m2, a refresh rate of 120HZ, three HDMI ports and a viewing angle of 176 degrees.
LCD monitor was employed with the following characteristics: 1,920 × 1,080 pixel resolution, widescreen ratio of 16:9 and brightness of 250 cd/m250
The proposed bi-layered structures of metallic WGP can achieve superior optical performance, such as the extinction ratio of 497 and brightness gain of 1.18, from 0° to 40° of incident angles at a wavelength of 650 nm of incident light.
The color peak signal-to-noise ratio (CPSNR), brightness of each region (bright and dark regions), and angular error are used to measure the spatial resolution, sensitivity, and color fidelity, respectively.
Magnitudes can be converted to light ratios by letting ln and lm be the brightnesses of stars of magnitudes n and m; the logarithm of the ratio of the two brightnesses then equals 0.4 times the difference between them i.e., log(lm/ln) = 0.4(n − m).
