S1, when ash cone 61 moves in the coverage of capture assembly 4, makes laser instrument 6 project to the hot spot of background board 3
61 produce relative displacement with ash cone 7, until the movement locus of hot spot 61 cover the entirely region corresponding to ash cone 7；Capture simultaneously
Assembly 4 is persistently shot.
Specifically, step S1 can be ash cone 7 static when hot spot 61 move：Drive ash cone 61 rotary motions, when ash cone
When in 61 coverages moving to capture assembly 4, stop the motion of ash cone 4, drive laser instrument 6 to project to the light of background board 3
Speckle 61 moves, and makes the movement locus of hot spot 61 cover the entirely corresponding region of ash cone.
Step S1 can also be ash cone 7 motion when hot spot 61 is static：When hot spot 61 is linear beam spot, make at hot spot 61
In resting state, ash cone 7 rotates with the rotation of supporting plate 5, when ash cone 7 rotate to intersect with hot spot 61 when, capture assembly 4 is to ash
Cone 7 is shot, until ash cone 7 rotates and completely disengages to hot spot 61, stops shooting.
S2, the picture that the hot spot 61 that laser instrument 6 is produced is shot with capture assembly 4 during ash cone 7 relative motion is synthesized,
Obtain complete grey diagram cone picture.
Embodiment two
The present embodiment two and embodiment one identical technology contents not repeated description, embodiment one disclosure falls within
The present embodiment two disclosure, the present embodiment two is with the difference of embodiment one：As shown in Figure 5 and Figure 6, this enforcement
In example, background board 3 is transmissive element, and laser instrument 6 is located at the outside of boiler tube 101, and the exit end of transmissive element is towards ash cone 7.By
When the light that laser instrument 6 projects is injected into background board 3, because background board 3 is the higher element of absorbance, most energy is equal
Background board 3 can be passed through, the background hot spot 61 of light tone is formed on background board 3.
Finally it should be noted that：Above example only in order to the technical solution of the utility model to be described, is not intended to limit；
