"spreading of light" is a correct and usable phrase in written English.
You can use it when describing something that is illuminating a large area, like a sunrise or the stars in the night sky. For example, you could write: "The morning sky was filled with a majestic spreading of light."
A comparison shows that the transferred LEDs have a higher concentrated brightness with no spreading of light, indicating an efficient enhancement of the light extraction efficiency.
The spreading of light is slower than in the diffusive regime, and it cannot be described by the standard diffusion equation.
Deconvolution methods work by estimating and then removing the contribution of light both from out-of-focus fluorescence and from in-plane spreading of light due to diffraction.
In contrast conventional S-SPECT pixels do share signals because of the spreading of light between them and this crosstalk degrades their effective pixel size.
25, 26 These images are then convolved with a 3-D model to account for the spreading of light through the microscope lens due to diffraction, as described below.
21 The spreading of light by diffraction through a microscope lens relative to the focal plane of the point light source is termed the "point spread function" (PSF), and can be either experimentally measured or theoretically calculated for a given microscope.
Hardly larger than a button, this device holds an L.E.D. flash that is designed for natural color and an even spread of light, powered by two replaceable lithium batteries.
The spreading of the light at the boundary of a large pinhole by diffraction is slight.
Saviours, the Saoshyants, would work toward the triumph of virtue and the spreading of heavenly light over all creation.
If the Enlightenment saw its pedagogical mission as the spreading of the light of reason, then Pestalozzi showed that it was not reason alone but love above all that would show a way out of the "mire of the world".
The quest for ultimate super resolution has been described in a short Review [1], treating incoherent super-resolution techniques, coherent super resolutions schemes, near field super-resolution techniques, etc. Quite long ago Silberberg [2] has shown that it is possible for self-focusing nonlinearity to compensate both spatial and temporal spreading of the light pulse.
