Embodiment Construction
[0014] According to attached figure 1 The diagram of the marked:
[0015] The pitch pointing mirror 1 is a plane mirror with adjustable pitch angle, and its function is to adjust the pitch angle value of the imaging field of view. The value of the pitch angle is generally adjusted before the system works, and the pitch pointing mirror 1 remains fixed after the integration of the detector starts.
[0016] The infrared telescopic lens 2 is an infrared optical system with no optical power, and its function is to compress the infinite parallel light beam at the entrance pupil to the exit pupil, and exit as parallel light. Its angular magnification is γ. It can be obtained from the characteristics of the telescopic optical system that the ratio of the entrance pupil size to the exit pupil size is also γ. The larger the γ, the smaller the size of the azimuth compensation oscillating mirror 3 in the subsequent optical path, which is beneficial for the motor to control the oscilla...
