Study on Active IR Imaging with Laser Illumiation

The fundamental theories and structure of the active IR imaging system with laser illumination, the manufacturing techniques and technical parameters of laser sources were presented. The optimization of optical systems and the receiving components were introduced. The parameters of the fiber-coupled LD for the collimated and homogenized night-vision laser illumination sources have been studied. The selection of CCD cameras corresponding to the spectra was described. A prototype active IR imaging system with laser illumination has been developed successfully and the acceptable images through various on-field experiments have been achieved. The system can be applied to not only security surveillances in the civil applications but also the automatic control for the light-weight weapons in the military fields, and also be equipped by the soldiers for night-vision purposes.
