Power supply feeder 10.
As shown in Fig. 2, 3 structure of heated filament light source are as follows: support frame 16 is arranged in horizontal plane, connects rectangle on support frame
The heated filament frame 12 of structure, upper and lower in heated filament frame 12 are respectively equipped with locking nut I 11, and locking nut I 11 is by the both ends of heated filament 13
It tenses at the middle part of heated filament frame 12, the position of heated filament 13 is corresponding with the focal position of infrared convex lens 5, divides on locking nut I 11
It Lian Jie not power supply lead wire 14.
As shown in figure 3,8 structure of runing rest is；It is equipped with the through-hole of axis horizontal on bracket 22, is set in through-hole
There is revolving part 21, one end of revolving part 21 is equipped with external screw thread, and connect locking with locking nut II 23 after bracket 22；It is propping up
The outer surface of frame 22 is equipped with reference reticle, and angle index line, angle index line position and reference graduation are equipped on revolving part 21
Position is corresponding.
The method debugged using alignment imaging position marker focal plane commissioning device, it is characterised in that the following steps are included:
1) it determines alignment direction: blocking the perforation hole of blackbody radiation source 1, it is burnt that infrared convex lens 5 is placed on debugging position marker 7
On point position, heated filament light source 3 is placed on before the perforation hole of blackbody radiation source 1, and the starting of direct-flow voltage regulation source 2 is supplied to heated filament light source 3
Electricity gives the debugging power supply gas supply of position marker 7, slowly rotates runing rest 8, observation oscilloscope 9, the alignment in debugging position marker 7
All members of detector have response, and when amplitude is equal, at this moment the alignment direction of detector array and 3 direction one of heated filament light source
It causes；
