High speed terahertz camera data are analyzed as processing module is used to read, and image is shown on computers.
When package passes through terahertz emission region with conveyer belt, terahertz emission penetrates the flammable oil product in package and package
And reach terahertz camera by conveyer belt.Analysis terahertz camera data are read by image processing and analyzing module, and will be at
As image is shown on computers.
Preferably, side on a moving belt, Terahertz lens and conveyer belt can be arranged in the Terahertz lens by holder
Spacing it is adjustable.The holder can realize that its height is adjustable by purely mechanic mode, cylinder or other well known method.
Preferably, the Terahertz lens are made of a piece of concave surface eyeglass and a piece of convex surface eyeglass, it is used for Terahertz
The THz wave of source transmitting is converted into parallel THz wave, so that the terahertz emission intensity for reaching conveyer belt radiation areas is equal
Even distribution improves the contrast being ultimately imaged.Concave surface eyeglass and a piece of convex surface eyeglass are all made of high resistant silicon material, opposite Terahertz
Wave has very high transmitance, transmitance to be higher than 99%.
The waveguide is preferably metal copper pipe, and inner surface coats 0.03mm thickness quartz medium films.Waveguide is used for
Shaping is carried out to the THz wave wave beam of THz source transmitting so that the THz wave being emitted from THz wave conduit is by setting
Meter angle is emitted and is received completely by Terahertz lens.And quartz medium film can then effectively reduce the loss of THz wave, improve
Reflectivity makes its reflectivity reach 99%.
140GHZ-10THZ THz sources can be used in the THz source, in order to preferably adapt to resolution ratio and radiation energy
Requirement, preferably 300GHZ THz sources.
In order to ensure that the good penetrability of THz source signal, the conveyer belt are preferably polytetrafluoroethylene (PTFE) material.
In order to adapt to different disposal speed, the conveyer belt is preferably speed conveyor belt with adjustable.Line speed adjusts model
It encloses for 0-1000mm/min, it is synchronous with terahertz camera.
For the ease of control, speed conveyor belt with adjustable can be connect with computer.
Terahertz camera described in the utility model is preferably high speed terahertz camera.
Compared to the prior art the active transmission-type Terahertz of the utility model wraps up the flammable online safety check apparatus of oil product,
With advantageous effect following prominent：
（One）Its presence or absence is determined according to its imaging features for flammable oil product present in package and determines its oil product
Type avoids searching package one by one, while reducing security staff's contact dangerous material by the possibility that dangerous material injure, and makes up
Package can fuel oil safety check technological gap.
（Two）By conveyer belt transmission can Rapid Detection package in can fuel oil dangerous material, further increase detection effect
Rate.
（Three）Terahertz lens can be needed to adjust according to actual safety check to the distance of conveyer belt and the transmission speed of conveyer belt
Degree, improves the scope of application and the flexibility of device.
Description of the drawings
Attached drawing 1 is that the active transmission-type Terahertz of the utility model wraps up the flammable online safety check apparatus structural representation of oil product
Figure；
Attached drawing 2 is the flow chart of data processing of safety check apparatus image processing module shown in Fig. 1.
Specific implementation mode
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, but not as to the utility model
Restriction.
