Method for measuring transverse position of weak pulse light spot

The invention relates to a method for measuring the transverse position of a weak pulse light spot, which comprises a pulse laser, a beam splitter, a camera, a photoelectric detector conversion plate, a signal processing plate and a computer, and is characterized in that the photoelectric detector conversion plate is used for carrying out high-speed photoelectric conversion on weak narrow pulse width signals output by the pulse laser; meanwhile, the pulse width of a weak narrow pulse width signal output by the pulse laser is broadened, and the pulse amplitude is subjected to rail-to-rail amplification; when the signal processing board receives that the number of the input pulses is equal to a set value, hardware signal triggering is carried out on the camera, multiple image pictures are continuously collected, and measurement of the transverse position of the pulse light spot is completed through a pulse light spot transverse position calculation formula. According to the invention, the requirement for real-t
