We experimentally demonstrate the intensity and angle control of interference image during all-optical logic (AOL) gate carrying orbital angular momentum (OAM) in a hot atomic ensemble. The variation of output signal intensity has been discovered by changing the detuning of input field. By changing the angle of reference light, we can also get obvious output signal modulation effects. Moreover, the transition of the interference pattern from parallel shape to spiral shape by changing the small angle is observed. This novel method of controlling AOL gate carrying OAM will further promoting the construction of all-optical networks with atomic ensembles.
