<p>In physics, the <b>phase problem</b> is the problem of loss of information concerning the <a href="page.php?w=phase_%28waves%29">phase</a> that can occur when making a physical measurement. The name comes from the field of <a href="page.php?w=X-ray_crystallography">X-ray crystallography</a>, where the phase problem has to be solved for the determination of a structure from <a href="page.php?w=diffraction">diffraction</a> data. The phase problem is also met in the fields of <a href="page.php?w=imaging_science">imaging</a> and <a href="page.php?w=signal_processing">signal processing</a>.</p><p>
