Everything about Closure phase

Observable quantity in imaging astronomical interferometry

The closure phase is an observable quantity in imaging astronomical interferometry, which allowed the use of interferometry with very long baselines. It forms the basis of the self-calibration approach to interferometric imaging. The observable which is usually used in most "closure phase" observations is actually the complex quantity called the triple product. The closure phase is the phase (argument) of this complex quantity. Wikipedia →
