Key performance indicators
● Focusing and scanning range, the focus position depends on both the focal length and the declination angle.
● The scanning range is proportional to the focal length of the scene. After focusing, the spot diameter is proportional to the focal length. That is, when the scanning area reaches a certain level, the larger the spot diameter is.
The role of laser focusing mirror
1. Improve the capability of detectors with incident light velocity at the edge.
2. In the same main optical system, the additional field lens will reduce the area of the detector. If the same detector area is used, the vision can be enlarged and the radiation flux can be increased.
3. Uniform illumination of the photosensitive surface of the detector can be homogenized.
