A liquid crystal panel module coupled in the image intensifier which has been coupled the magnetic mirror has been
proposed. The normal imaging under strong light and the part gating of light intensity control can be achieved by
changing the transmittance of these pixel points which is changed by the voltage imposed on pixel points. Influence of
the response time and transmittance of the liquid crystal to the entire system have been researched, that liquid crystal can
achieve part gating function has been confirmed through experiments. Liquid crystal display module (LCP)'s response
time is 22ms by using the 650nm, 4mw SZ-04 laser and the transmittance of LCP ranges from 1.28 to 25.60%.It has
been proved that the liquid crystal selected in this article fit for the entire LCP. Photography effect graphs achieved by
part gating of light intensity have been got.
