Phase Problem

In physics the phase problem is the name given to the problem of loss of information concerning the phase that can occur when making a physical measurement. The name itself comes from the field of x-ray crystallography, where the phase problem has to be solved for the determination of a structure from diffraction data. The phase problem is also met in the fields of imaging and signal processing. Various approaches have been developed over the years to solve it.

Famous quotes containing the words problem and/or phase:

    Hypocrisy is the essence of snobbery, but all snobbery is about the problem of belonging.
    Alexander Theroux (b. 1940)

    I had let preadolescence creep up on me without paying much attention—and I seriously underestimated this insidious phase of child development. You hear about it, but you’re not a true believer until it jumps out at you in the shape of your own, until recently quite companionable child.
    Susan Ferraro (20th century)
