sensitivity function

sensitivity function

[‚sen·sə′tiv·əd·ē ‚fəŋk·shən]
(control systems)
The ratio of the fractional change in the system response of a feedback-compensated feedback control system to the fractional change in an open-loop parameter, for some specified parameter variation.

The light sensor integrates the light arriving from a spatially distributed region within its field of view weighted by its spatial sensitivity function (SSF).
The breakthrough is significant because it was previously thought that the ability to notice even very small changes in shades of grey against a uniform background, called the contrast sensitivity function (CSF), could not be improved, Telegraph reported.
The sensitivity of the eye to different wavelengths is described by the relative spectral sensitivity function. In 1924 the CIE introduced the spectral luminous efficiency function V([lambda]) for photopic vision [CIE 1926], which is based on the responsivity of the cones.
In our system we have considered Contrast sensitivity function to find out the acuity and simplifying the image.
Efficient solving of the sensitivity function was deduced here.
Contrast sensitivity function is often overlooked as a critical need for and predictor of the selection and preference for low vision devices.
Contrast sensitivity function in children: Normalized notation for the assessment and diagnosis of diseases.
During the study, the researchers recruited 22 students and tested their contrast sensitivity function.
where S = 1/1 + GC is the achieved (or true) sensitivity function and T = GC/1 + GC is the achieved complementary sensitive function.
The spectral sensitivity function for dark-adapted specimens of Abyssorchomene plebs shows a major peak in the blue, with a minor sensitivity peak in the ultraviolet (UV).
This paper analyzes empirical constraints from the shape of the contrast sensitivity function (CSF) at several illuminance levels and from the relationship between illuminance and visual acuity, showing that the DeVries-Rose to Weber transition with sine-wave gratings can only hold at very low spatial frequencies.
