"light contribution" is correct and usable in written English.
You can use it to describe a small contribution someone or something has made towards a cause or project. For example, "She made a light contribution to the charity fundraiser by donating a few baked goods."
Since this is something we typically do not and cannot know, and since it is impractical to turn off all the room lights during scanning we cannot assume that the only light contribution to the pictures we take is our light.
For instance, comparing the percentage of light contribution of GA and CitA into the 481 and 595 nm channels (Table 2) sufficed to distinguish the dissimilar luminescence spectra caused by the 20 nm emission red shift of citrine compared to GFP.
This approach limits the degree of details one can obtain as the camera integrates light from the object, resulting in a planar picture, which is dominated by the light contribution from the first 1 2 mm of tissue.
A specific study has been devoted to investigate the image uniformity, separating the light contributions due to the different lens regions.
Re-measuring the filter transmissions with the spectrometers also allows a very accurate determination of the changing second order (optical) efficiencies of the spectrometers as well as the stray light contributions to the spectral recording in different wavelength ranges.
In Chapter 4, we present the subtractive shadow filter, which derives from the principle that rather than adding unshadowed light contributions from multiple lights in the scene to produce a shadowed result, we rather subtract extraneous light from an unshadowed rendering.
The model takes into account the light contributions from the volume of water between the scene and the camera.
Instead of adding illumination contributions at each pixel across various lights, we compute the complete, unshadowed local illumination at each pixel using fast approximation algorithms, then subtract the lighting contribution from each light for which the pixel is in shadow.
Gina Scherr's substantial lighting contributions include intimate silhouettes and a descending chandelier of candlelike facets.
The reducing strength of TiO2 pigment describes the light-scattering contribution relative to its light absorbing ability.
Steric and electrostatic field effects are discussed in the light of contribution plot generated.
