Typically in optical microscopy, the signal-to-noise ratio (SNR) is calculated to quantify the image contrast which indicates how well different regions of interest in the image can be differentiated.

Fine-scale exogenous attention within the foveola selectively enhances contrast gain at low-to-mid spatial frequencies while increasing response gain across a broad spatial frequency range.

The sensitivity of radiochromic films to UV-blue light is increasingly considered for light dosimetry purposes, owing to their bidimensional detection capabilities and ease of use. While film response ...
