Paper Abstract

Laser decoy is widely used in the field of electro-optical countermeasures, against laser guided semi-automatic weapons. Decoy laser usually includes a laser light source with specific wavelength and signal, whose energy distribution has Lambertian reflection characteristics. With a 633nm laser source, a fibre and a diffusive module, a homogeneous field laser was illustrated, which was generated through high-density colloidal dispersion to get diffused. By optimizing the fibre and structure parameters, the laser light energy utilization was improved while maintain light field uniformity. Additionally, the flat field system was designed and tested using high reflectivity PTFE material, with a reflectivity of 97%. A developed Lambertian light source system for reference-based Laser decoy was established, whose non-uniformity was lower than 0.3%. The results showed that the Lambertian light source system could meet the requirement of Laser decoy, and needed to be improved in near infrared.
