1a) To bend down; slope downward; descend.
M.E. declinen, from O.Fr. decliner "to sink, decline, degenerate, turn aside," from declinare "to turn away, inflect," from → de- + clinare "to bend," cf. Gk. klinein "to cause to slope, slant, incline," Skt. sri- "to lean," O.Pers. θray-, Av. sray- "to lean," Mod.Pers. kil "bent, inclined, slant," PIE base *klei- "to lean, incline" from which is also derived (Ger. lehnen, E. lean).

1) A gradual decrease in surrounding → pressure,
especially the controlled decrease in pressure that divers undergo
after working in deep water or breathing compressed air.
A mathematical operation that allows to restore the original input signal, such as an astronomical image or spectrum, to its state before being affected by the → atmospheric turbulence and the → transfer function of the instrument. → convolution.
Fr.: logiciel de déconvolution, algorithme ~ ~
An algorithm used to improve the resolution of an image particularly when the convolving function is well defined. Also called deconvolution code.
Verbal form of → deconvolution.
1) To separate or detach; to cause to become disconnected or divergent.
Cosmology: In the early history of the Universe, separation of matter and radiation due to their non-interaction. At a redshift of 1000, that is about 400,000 years after the Big Bang, the temperature would have cooled to the point (4000 degrees Kelvin) where electrons and nuclei can recombine and form neutral hydrogen atoms. Since atoms do not scatter the radiation appreciably, free electrons were lacking, and the Universe became transparent to radiation. Same as → recombination. See also → decoupling era.
