Abstract

Methods and devices for inspecting liquid are disclosed. According to the method, it is firstly determined whether the package of the liquid is transparent, semi-transparent, or opaque; in a case that the package of the liquid is transparent or semi-transparent, Raman spectrum analysis is implemented by a Raman spectrum module on the inspected liquid to judge whether the inspected liquid is dangerous or is suspected; and in a case that the package of the inspected liquid is opaque, the inspected liquid are inspected by using an X-ray dual-energy scanning technology to judge whether the inspected liquid is dangerous or is suspected. The above solution has advantages that the inspection speed is high, the material can be recognized, it is suitable for various packing materials with various shapes, the accuracy of the inspection result is high or the like. Therefore, the solution is suitable for security inspection in public places with high security inspection requirements, complicated inspected liquids, high personnel flow rate or the like.
