In the current security and explosive disposal work, X-ray detection has become the main means to detect suspicious objects. However, general X-ray detection needs to arrange a light source and a detector at both ends of the object to be inspected, and the arrangement is complex, and can only detect ground objects, and can not detect objects near the wall or hanging positions. At the same time, the X-ray detected by transmission is not sensitive to low density organic matter (explosives, drugs). Therefore, the backscattering technique of single-sided imaging has become an important means to solve the above problems.

Handheld security inspection equipment can be applied in many fields:
Narcotics and explosives detection: 
Non-intrusive imaging inspection of boxes, seats, tires in cars, passenger vehicles and trucks, as well as parcels.
Listening devices and explosives inspection: 
Non-intrusive inspection of interlayers, seats, ceilings and inner layers of office desks in important conference rooms.
