Issues of laser safety of visual landing systems

The paper discusses the methodic issues and theoretical results of determining the boundaries of laser hazard zones (LHZs) when the eye is exposed to direct and scattered radiation produced by a laser landing system (LLS). We consider algorithms for LHZ calculation when LLSs are observed under real conditions of exploitation. The LHZ calculations for single and multiple laser sources under different meteorological conditions are presented. Computer software is provided to calculate the dosimetry of laser radiation under real conditions of LLS operation.
