热象仪扫描头的调试,主要是光学系统的调试。本热象仪扫描头的光学系统是折、反射式的象方扫描。两维扫描是由摆动的平面反射次镜完成垂直扫描;由旋转的透射棱镜完成水平扫描。调试要达到的目的主要有两项,一是光学系统的各光学元件的光轴要同轴;一是将已同轴的各光学元件之间距离调整到符合设计要求,使二次成象象点落在探测器的光敏面上,探测器给出最佳信号。其光学系统如图示(图一)。
Thermal image scanner scanning head, mainly optical system debugging. The optical system of the thermal imager scanner is folded, reflective image-side scanning. The two-dimensional scanning is performed by the wobbled plane reflecting secondary mirror to complete the vertical scanning; the rotating transmission prism completes the horizontal scanning. Debugging to achieve the main two, one optical system optical axis of the optical axis to be coaxial; one is to have the coaxial optical elements distance adjusted to meet the design requirements, the secondary imaging image Point on the photosensitive surface of the detector, the detector gives the best signal. The optical system as shown (Figure 1).
