The targets of atomic molecular physics are atoms or molecules consist of a few atoms. Due to their simple geometrical structure, in order to obtain unrevealed properties, the advanced experimental techniques are often required to view the target from multi viewpoints and follow the history of the relevant states if possible. This scientific desire drives us to promote the technical specification and flexibility of instruments. Here, we reviewed several coincident setup, they are based on: field free electron time of flight spectrometer, electron energy-dispersive analyzer, magnetic bottle spectrometer, reaction microscope and velocity map imaging spectrometer. They are widely used in the experiments based on ultrafast laser, free electron laser and synchrotron radiation. We give not only the description of the working principles and the technical differences among them, but also put emphasize on the recent scientific desires and possible breakthroughs.
