The X-ray pulse that the second X-ray generating means is produced is the second X-ray pulse, the phase of the first X-ray pulse and described second
The phase of X-ray pulse is differed；
S35, the first X-ray pulse total cycle it is identical with upper cycle limit, the duration is T1, the second X-ray pulse it is total
Cycle is identical with upper cycle limit, and the duration is T2, the first X-ray pulse overlapping with the second X-ray pulse is Tt, institute
State T1Zequin for the first X-ray pulse rising edge midpoint, terminal be the first X-ray pulse trailing edge
Midpoint；The T2Zequin for the second X-ray pulse rising edge midpoint, terminal be second X-ray
The midpoint of the trailing edge of pulse；And meet T1+T2≤T+Tt,
S40, first video receiver and the second video receiver receive the first X-ray pulse and the 2nd X respectively
The X-ray pulse of detected object is penetrated in light pulse, and generates visible light signal；
S50, first video camera and the second video camera gather first video receiver respectively and the second image is received
The visible light signal that device is generated, and described image processor is transferred to by network interface card；
S60, described image processor show the visible light signal that first video camera is gathered to first display,
The visible light signal that second video camera is gathered is shown to the second display.
2. the synchronous real time imagery method of X-ray out-phase pulse biplane according to claim 1, it is characterised in that described
In step S35, T1With T2Differ.
